By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW.

Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Nothing is +sent anywhere without your consent. + +These are the basics, but there's much more you can do. The following sections +cover installation, usage and hosting of the recordings in more detail. + +## Installation + +### Python package from PyPI + +[pypi]: https://pypi.python.org/pypi/asciinema + +asciinema is available on [PyPI] and can be installed with +[pipx](https://pypa.github.io/pipx/) (if you have it) or with pip (Python 3 +with setuptools required): + +```sh +pipx install asciinema +``` + +Or with pip (using your preferred Python version): + +```sh +python3 -m pip install asciinema +``` + +Installing from [PyPI] is the recommended way of installation, which gives you the latest released version. + +### Native packages + +asciinema is included in repositories of most popular package managers on Mac OS +X, Linux and FreeBSD. Look for package named `asciinema`. See the +[list of available packages](https://asciinema.org/docs/installation). + +### Running latest version from source code checkout + +If you can't use Python package or native package for your OS is outdated you +can clone the repo and run asciinema straight from the checkout. + +Clone the repo: + +```sh +git clone https://github.com/asciinema/asciinema.git +cd asciinema +``` + +If you want latest stable version: + +```sh +git checkout master +``` + +If you want current development version: + +```sh +git checkout develop +``` + +Then run it with: + +```sh +python3 -m asciinema --version +``` + +### Docker image + +asciinema Docker image is based on [Ubuntu +20.04](https://releases.ubuntu.com/20.04/) and has the latest version of +asciinema recorder pre-installed. + +```sh +docker pull docker.io/asciinema/asciinema +``` + +When running it don't forget to allocate a pseudo-TTY (`-t`), keep STDIN open +(`-i`) and mount config directory volume (`-v`): + +```sh +docker run --rm -it -v "${HOME}/.config/asciinema:/root/.config/asciinema" docker.io/asciinema/asciinema rec +``` + +Container's entrypoint is set to `/usr/local/bin/asciinema` so you can run the +container with any arguments you would normally pass to `asciinema` binary (see +Usage section for commands and options). + +There's not much software installed in this image though. In most cases you may +want to install extra programs before recording. One option is to derive new +image from this one (start your custom Dockerfile with `FROM asciinema/asciinema`). Another option is to start the container with `/bin/bash` +as the entrypoint, install extra packages and manually start `asciinema rec`: + +```console +docker run --rm -it -v "${HOME}/.config/asciinema:/root/.config/asciinema" --entrypoint=/bin/bash docker.io/asciinema/asciinema rec +root@6689517d99a1:~# apt-get install foobar +root@6689517d99a1:~# asciinema rec +``` + +It is also possible to run the docker container as a non-root user, which has +security benefits. You can specify a user and group id at runtime to give the +application permission similar to the calling user on your host. + +```sh +docker run --rm -it \ + --env=ASCIINEMA_CONFIG_HOME="/run/user/$(id -u)/.config/asciinema" \ + --user="$(id -u):$(id -g)" \ + --volume="${HOME}/.config/asciinema:/run/user/$(id -u)/.config/asciinema:rw" \ + --volume="${PWD}:/data:rw" \ + --workdir='/data' \ + docker.io/asciinema/asciinema rec +``` + +## Usage + +asciinema is composed of multiple commands, similar to `git`, `apt-get` or +`brew`. + +When you run `asciinema` with no arguments help message is displayed, listing +all available commands with their options. + +### `rec [filename]` + +**Record terminal session.** + +By running `asciinema rec [filename]` you start a new recording session. The +command (process) that is recorded can be specified with `-c` option (see +below), and defaults to `$SHELL` which is what you want in most cases. + +You can temporarily pause the capture of your terminal by pressing +<kbd>Ctrl+\\</kbd>. This is useful when you want to execute some commands during +the recording session that should not be captured (e.g. pasting secrets). Resume +by pressing <kbd>Ctrl+\\</kbd> again. When pausing desktop notification is +displayed so you're sure the sensitive output won't be captured in the +recording. + +Recording finishes when you exit the shell (hit <kbd>Ctrl+D</kbd> or type +`exit`). If the recorded process is not a shell then recording finishes when +the process exits. + +If the `filename` argument is omitted then (after asking for confirmation) the +resulting asciicast is uploaded to +[asciinema-server](https://github.com/asciinema/asciinema-server) (by default to +asciinema.org), where it can be watched and shared. + +If the `filename` argument is given then the resulting recording (called +[asciicast](doc/asciicast-v2.md)) is saved to a local file. It can later be +replayed with `asciinema play <filename>` and/or uploaded to asciinema server +with `asciinema upload <filename>`. + +`ASCIINEMA_REC=1` is added to recorded process environment variables. This +can be used by your shell's config file (`.bashrc`, `.zshrc`) to alter the +prompt or play a sound when the shell is being recorded. + +Available options: + +- `--stdin` - Enable stdin (keyboard) recording (see below) +- `--append` - Append to existing recording +- `--raw` - Save raw STDOUT output, without timing information or other metadata +- `--overwrite` - Overwrite the recording if it already exists +- `-c, --command=<command>` - Specify command to record, defaults to $SHELL +- `-e, --env=<var-names>` - List of environment variables to capture, defaults + to `SHELL,TERM` +- `-t, --title=<title>` - Specify the title of the asciicast +- `-i, --idle-time-limit=<sec>` - Limit recorded terminal inactivity to max `<sec>` seconds +- `--cols=<n>` - Override terminal columns for recorded process +- `--rows=<n>` - Override terminal rows for recorded process +- `-y, --yes` - Answer "yes" to all prompts (e.g. upload confirmation) +- `-q, --quiet` - Be quiet, suppress all notices/warnings (implies -y) + +Stdin recording allows for capturing of all characters typed in by the user in +the currently recorded shell. This may be used by a player (e.g. +[asciinema-player](https://github.com/asciinema/asciinema-player)) to display +pressed keys. Because it's basically a key-logging (scoped to a single shell +instance), it's disabled by default, and has to be explicitly enabled via +`--stdin` option. + +### `play <filename>` + +**Replay recorded asciicast in a terminal.** + +This command replays given asciicast (as recorded by `rec` command) directly in +your terminal. + +Following keyboard shortcuts are available by default: + +- <kbd>Space</kbd> - toggle pause, +- <kbd>.</kbd> - step through a recording a frame at a time (when paused), +- <kbd>Ctrl+C</kbd> - exit. + +See "Configuration file" section for information on how to customize the +keyboard shortcuts. + +Playing from a local file: + +```sh +asciinema play /path/to/asciicast.cast +``` + +Playing from HTTP(S) URL: + +```sh +asciinema play https://asciinema.org/a/22124.cast +asciinema play http://example.com/demo.cast +``` + +Playing from asciicast page URL (requires `<link rel="alternate" type="application/x-asciicast" href="/my/ascii.cast">` in page's HTML): + +```sh +asciinema play https://asciinema.org/a/22124 +asciinema play http://example.com/blog/post.html +``` + +Playing from stdin: + +```sh +cat /path/to/asciicast.cast | asciinema play - +ssh user@host cat asciicast.cast | asciinema play - +``` + +Playing from IPFS: + +```sh +asciinema play dweb:/ipfs/QmNe7FsYaHc9SaDEAEXbaagAzNw9cH7YbzN4xV7jV1MCzK/ascii.cast +``` + +Available options: + +- `-i, --idle-time-limit=<sec>` - Limit replayed terminal inactivity to max `<sec>` seconds +- `-s, --speed=<factor>` - Playback speed (can be fractional) + +> For the best playback experience it is recommended to run `asciinema play` in +> a terminal of dimensions not smaller than the one used for recording, as +> there's no "transcoding" of control sequences for new terminal size. + +### `cat <filename>` + +**Print full output of recorded asciicast to a terminal.** + +While `asciinema play <filename>` replays the recorded session using timing +information saved in the asciicast, `asciinema cat <filename>` dumps the full +output (including all escape sequences) to a terminal immediately. + +`asciinema cat existing.cast >output.txt` gives the same result as recording via +`asciinema rec --raw output.txt`. + +### `upload <filename>` + +**Upload recorded asciicast to asciinema.org site.** + +This command uploads given asciicast (recorded by `rec` command) to +asciinema.org, where it can be watched and shared. + +`asciinema rec demo.cast` + `asciinema play demo.cast` + `asciinema upload demo.cast` is a nice combo if you want to review an asciicast before +publishing it on asciinema.org. + +### `auth` + +**Link your install ID with your asciinema.org user account.** + +If you want to manage your recordings (change title/theme, delete) at +asciinema.org you need to link your "install ID" with asciinema.org user +account. + +This command displays the URL to open in a web browser to do that. You may be +asked to log in first. + +Install ID is a random ID ([UUID +v4](https://en.wikipedia.org/wiki/Universally_unique_identifier)) generated +locally when you run asciinema for the first time, and saved at +`$HOME/.config/asciinema/install-id`. Its purpose is to connect local machine +with uploaded recordings, so they can later be associated with asciinema.org +account. This way we decouple uploading from account creation, allowing them to +happen in any order. + +> A new install ID is generated on each machine and system user account you use +> asciinema on, so in order to keep all recordings under a single asciinema.org +> account you need to run `asciinema auth` on all of those machines. + +> asciinema versions prior to 2.0 confusingly referred to install ID as "API +> token". + +## Hosting the recordings on the web + +As mentioned in the `Usage > rec` section above, if the `filename` argument to +`asciinema rec` is omitted then the recorded asciicast is uploaded to +[asciinema.org](https://asciinema.org). You can watch it there and share it via +secret URL. + +If you prefer to host the recordings yourself, you can do so by either: + +- recording to a file (`asciinema rec demo.cast`), and using [asciinema's + standalone web + player](https://github.com/asciinema/asciinema-player#self-hosting-quick-start) + in your HTML page, or +- setting up your own + [asciinema-server](https://github.com/asciinema/asciinema-server) instance, + and [setting API URL + accordingly](https://github.com/asciinema/asciinema-server/wiki/Installation-guide#using-asciinema-recorder-with-your-instance). + +## Configuration file + +You can configure asciinema by creating config file at +`$HOME/.config/asciinema/config`. + +Configuration is split into sections (`[api]`, `[record]`, `[play]`). Here's a +list of all available options for each section: + +```ini +[api] + +; API server URL, default: https://asciinema.org +; If you run your own instance of asciinema-server then set its address here +; It can also be overriden by setting ASCIINEMA_API_URL environment variable +url = https://asciinema.example.com + +[record] + +; Command to record, default: $SHELL +command = /bin/bash -l + +; Enable stdin (keyboard) recording, default: no +stdin = yes + +; List of environment variables to capture, default: SHELL,TERM +env = SHELL,TERM,USER + +; Limit recorded terminal inactivity to max n seconds, default: off +idle_time_limit = 2 + +; Answer "yes" to all interactive prompts, default: no +yes = true + +; Be quiet, suppress all notices/warnings, default: no +quiet = true + +; Define hotkey for pausing recording (suspending capture of output), +; default: C-\ (control + backslash) +pause_key = C-p + +; Define hotkey prefix key - when defined other recording hotkeys must +; be preceeded by it, default: no prefix +prefix_key = C-a + +[play] + +; Playback speed (can be fractional), default: 1 +speed = 2 + +; Limit replayed terminal inactivity to max n seconds, default: off +idle_time_limit = 1 + +; Define hotkey for pausing/resuming playback, +; default: space +pause_key = p + +; Define hotkey for stepping through playback, a frame at a time, +; default: . +step_key = ] + +[notifications] +; Desktop notifications are displayed on certain occasions, e.g. when +; pausing/resuming the capture of terminal with C-\ keyboard shortcut. + +; Should desktop notifications be enabled, default: yes +enabled = no + +; Custom notification command +; asciinema automatically detects available desktop notification system +; (notify-send on GNU/Linux, osacript/terminal-notifier on macOS).

DESCRIPTION +.PP +asciinema lets you easily record terminal sessions, replay them in a +terminal as well as in a web browser and share them on the web. +asciinema is Free and Open Source Software licensed under the GNU +General Public License v3. +.SH COMMANDS +.PP +asciinema is composed of multiple commands, similar to \f[V]git\f[R], +\f[V]apt-get\f[R] or \f[V]brew\f[R]. +.PP +When you run \f[B]asciinema\f[R] with no arguments a help message is +displayed, listing all available commands with their options. +.SS rec [\f[I]filename\f[R]] +.PP +Record terminal session. +.PP +By running \f[B]asciinema rec [filename]\f[R] you start a new recording +session. +The command (process) that is recorded can be specified with +\f[B]-c\f[R] option (see below), and defaults to \f[B]$SHELL\f[R] which +is what you want in most cases. +.PP +You can temporarily pause recording of terminal by pressing Ctrl+\[rs]. +This is useful when you want to execute some commands during the +recording session that should not be captured (e.g.\ pasting secrets). +Resume by pressing Ctrl+\[rs] again. +.PP +Recording finishes when you exit the shell (hit Ctrl+D or type +\f[V]exit\f[R]). +If the recorded process is not a shell then recording finishes when the +process exits. +.PP +If the \f[I]filename\f[R] argument is omitted then (after asking for +confirmation) the resulting asciicast is uploaded to +asciinema-server (https://github.com/asciinema/asciinema-server) (by +default to asciinema.org), where it can be watched and shared. +.PP +If the \f[I]filename\f[R] argument is given then the resulting recording +(called asciicast) is saved to a local file. +It can later be replayed with \f[B]asciinema play <filename>\f[R] and/or +uploaded to asciinema server with \f[B]asciinema upload <filename>\f[R]. +.PP +\f[B]ASCIINEMA_REC=1\f[R] is added to recorded process environment +variables. +This can be used by your shell\[cq]s config file (\f[V].bashrc\f[R], +\f[V].zshrc\f[R]) to alter the prompt or play a sound when the shell is +being recorded. +.TP +Available options: +\ +.RS +.TP +\f[V]--stdin\f[R] +Enable stdin (keyboard) recording (see below) +.TP +\f[V]--append\f[R] +Append

all characters typed in by the +user in the currently recorded shell. +This may be used by a player (e.g. +asciinema-player (https://github.com/asciinema/asciinema-player)) to +display pressed keys.

\[_options_] \[_args_] + + +DESCRIPTION +=========== + +asciinema lets you easily record terminal sessions, replay +them in a terminal as well as in a web browser and share them on the web. +asciinema is Free and Open Source Software licensed under +the GNU General Public License v3. + + +COMMANDS +======== + +asciinema is composed of multiple commands, similar to `git`, `apt-get` or +`brew`. + +When you run **asciinema** with no arguments a help message is displayed, listing +all available commands with their options. + + +rec [_filename_] +--- + +Record terminal session. + +By running **asciinema rec [filename]** you start a new recording session. The +command (process) that is recorded can be specified with **-c** option (see +below), and defaults to **$SHELL** which is what you want in most cases. + +You can temporarily pause the capture of your terminal by pressing +<kbd>Ctrl+\\</kbd>. This is useful when you want to execute some commands during +the recording session that should not be captured (e.g. pasting secrets). Resume +by pressing <kbd>Ctrl+\\</kbd> again. When pausing desktop notification is +displayed so you're sure the sensitive output won't be captured in the +recording. + +Recording finishes when you exit the shell (hit <kbd>Ctrl+D</kbd> or type +`exit`). If the recorded process is not a shell then recording finishes when +the process exits. + +If the _filename_ argument is omitted then (after asking for confirmation) the +resulting asciicast is uploaded to +[asciinema-server](https://github.com/asciinema/asciinema-server) (by default to +asciinema.org), where it can be watched and shared. + +If the _filename_ argument is given then the resulting recording (called +[asciicast](doc/asciicast-v2.md)) is saved to a local file. It can later be +replayed with **asciinema play \<filename>** and/or uploaded to asciinema server +with **asciinema upload \<filename>**. + +**ASCIINEMA_REC=1** is added to recorded process environment variables. This +can be used by your shell's config file (`.bashrc`, `.zshrc`) to alter the +prompt or play a sound when the shell is being recorded. + +Available options: + +: + + `--stdin` + : Enable stdin (keyboard) recording (see below) + + `--append` + : Append to existing recording + + `--raw` + : Save raw STDOUT output, without timing information or other metadata + + `--overwrite` + : Overwrite the recording if it already exists + + `-c, --command=<command>` + : Specify command to record, defaults to **$SHELL** + + `-e, --env=<var-names>` + : List of environment variables to capture, defaults to **SHELL,TERM** + + `-t, --title=<title>` + : Specify the title of the asciicast + + `-i, --idle-time-limit=<sec>` + : Limit recorded terminal inactivity to max `<sec>` seconds + + `--cols=<n>` + : Override terminal columns for recorded process + + `--rows=<n>` + : Override terminal rows for recorded process + + `-y, --yes` + : Answer "yes" to all prompts (e.g. upload confirmation) + + `-q, --quiet` + : Be quiet, suppress all notices/warnings (implies **-y**) + +Stdin recording allows for capturing of all characters typed in by the user in +the currently recorded shell. This may be used by a player (e.g. +[asciinema-player](https://github.com/asciinema/asciinema-player)) to display +pressed keys. Because it's basically a key-logging (scoped to a single shell +instance), it's disabled by default, and has to be explicitly enabled via +**--stdin** option. + + +play <_filename_> +--- + +Replay recorded asciicast in a terminal. + +This command replays a given asciicast (as recorded by **rec** command) directly in +your terminal.
