If <prefix> is specified it is +prepended to the filenames in the archive. + +'git archive' behaves differently when given a tree ID as opposed to a +commit ID or tag ID. When a tree ID is provided, the current time is +used as the modification time of each file in the archive. On the +other hand, when a commit ID or tag ID is provided, the commit time as +recorded in the referenced commit object is used instead. +Additionally the commit ID is stored in a global extended pax header +if the tar format is used; it can be extracted using 'git +get-tar-commit-id'. In ZIP files it is stored as a file comment. + +OPTIONS +------- + +--format=<fmt>:: + Format of the resulting archive. Possible values are `tar`, + `zip`, `tar.gz`, `tgz`, and any format defined using the + configuration option `tar.<format>.command`. If `--format` + is not given, and the output file is specified, the format is + inferred from the filename if possible (e.g. writing to `foo.zip` + makes the output to be in the `zip` format). Otherwise the output + format is `tar`. + +-l:: +--list:: + Show all available formats. + +-v:: +--verbose:: + Report progress to stderr. + +--prefix=<prefix>/:: + Prepend <prefix>/ to paths in the archive. Can be repeated; its + rightmost value is used for all tracked files. See below which + value gets used by `--add-file` and `--add-virtual-file`. + +-o <file>:: +--output=<file>:: + Write the archive to <file> instead of stdout. + +--add-file=<file>:: + Add a non-tracked file to the archive. Can be repeated to add + multiple files. The path of the file in the archive is built by + concatenating the value of the last `--prefix` option (if any) + before this `--add-file` and the basename of <file>. + +--add-virtual-file=<path>:<content>:: + Add the specified contents to the archive. Can be repeated to add + multiple files. The path of the file in the archive is built + by concatenating the value of the last `--prefix` option (if any) + before this `--add-virtual-file` and `<path>`. ++ +The `<path>` argument can start and end with a literal double-quote +character; the contained file name is interpreted as a C-style string, +i.e. the backslash is interpreted as escape character. The path must +be quoted if it contains a colon, to avoid the colon from being +misinterpreted as the separator between the path and the contents, or +if the path begins or ends with a double-quote character. ++ +The file mode is limited to a regular file, and the option may be +subject to platform-dependent command-line limits. For non-trivial +cases, write an untracked file and use `--add-file` instead. + +--worktree-attributes:: + Look for attributes in .gitattributes files in the working tree + as well (see <<ATTRIBUTES>>). + +--mtime=<time>:: + Set modification time of archive entries. Without this option + the committer time is used if `<tree-ish>` is a commit or tag, + and the current time if it is a tree. + +<extra>:: + This can be any options that the archiver backend understands. + See next section. + +--remote=<repo>:: + Instead of making a tar archive from the local repository, + retrieve a tar archive from a remote repository. Note that the + remote repository may place restrictions on which sha1 + expressions may be allowed in `<tree-ish>`. See + linkgit:git-upload-archive[1] for details. + +--exec=<git-upload-archive>:: + Used with --remote to specify the path to the + 'git-upload-archive' on the remote side. + +<tree-ish>:: + The tree or commit to produce an archive for. + +<path>:: + Without an optional path parameter, all files and subdirectories + of the current working directory are included in the archive. + If one or more paths are specified, only these are included. + +BACKEND EXTRA OPTIONS +--------------------- + +zip +~~~ +-<digit>:: + Specify compression level. Larger values allow the command + to spend more time to compress to smaller size. Supported + values are from `-0` (store-only) to `-9` (best ratio). + Default is `-6` if not given. + +tar +~~~ +-<number>:: + Specify compression level. The value will be passed to the + compression command configured in `tar.<format>.command`. See + manual page of the configured command for the list of supported + levels and the default level if this option isn't specified. + +CONFIGURATION +------------- + +tar.umask:: + This variable can be used to restrict the permission bits of + tar archive entries. The default is 0002, which turns off the + world write bit. The special value "user" indicates that the + archiving user's umask will be used instead. See umask(2) for + details. If `--remote` is used then only the configuration of + the remote repository takes effect. + +tar.<format>.command:: + This variable specifies a shell command through which the tar + output generated by `git archive` should be piped. The command + is executed using the shell with the generated tar file on its + standard input, and should produce the final output on its + standard output. Any compression-level options will be passed + to the command (e.g., `-9`). ++ +The `tar.gz` and `tgz` formats are defined automatically and use the +magic command `git archive gzip` by default, which invokes an internal +implementation of gzip. + +tar.<format>.remote:: + If true, enable the format for use by remote clients via + linkgit:git-upload-archive[1]. Defaults to false for + user-defined formats, but true for the `tar.gz` and `tgz` + formats. + +[[ATTRIBUTES]] +ATTRIBUTES +---------- + +export-ignore:: + Files and directories with the attribute export-ignore won't be + added to archive files. See linkgit:gitattributes[5] for details. + +export-subst:: + If the attribute export-subst is set for a file then Git will + expand several placeholders when adding this file to an archive. + See linkgit:gitattributes[5] for details. + +Note that attributes are by default taken from the `.gitattributes` files +in the tree that is being archived. If you want to tweak the way the +output is generated after the fact (e.g. you committed without adding an +appropriate export-ignore in its `.gitattributes`), adjust the checked out +`.gitattributes` file as necessary and use `--worktree-attributes` +option. Alternatively you can keep necessary attributes that should apply +while archiving any tree in your `$GIT_DIR/info/attributes` file. + +EXAMPLES +-------- +`git archive --format=tar --prefix=junk/ HEAD | (cd /var/tmp/ && tar xf -)`:: + + Create a tar archive that contains the contents of the + latest commit on the current branch, and extract it in the + `/var/tmp/junk` directory. + +`git archive --format=tar --prefix=git-1.4.0/ v1.4.0 | gzip >git-1.4.0.tar.gz`:: + + Create a compressed tarball for v1.4.0 release. + +`git archive --format=tar.gz --prefix=git-1.4.0/ v1.4.0 >git-1.4.0.tar.gz`:: + + Same as above, but using the builtin tar.gz handling. + +`git archive --prefix=git-1.4.0/ -o git-1.4.0.tar.gz v1.4.0`:: + + Same as above, but the format is inferred from the output file. + +`git archive --format=tar --prefix=git-1.4.0/ v1.4.0^{tree} | gzip >git-1.4.0.tar.gz`:: + + Create a compressed tarball for v1.4.0 release, but without a + global extended pax header. + +`git archive --format=zip --prefix=git-docs/ HEAD:Documentation/ > git-1.4.0-docs.zip`:: + + Put everything in the current head's Documentation/ directory + into 'git-1.4.0-docs.zip', with the prefix 'git-docs/'. + +`git archive -o latest.zip HEAD`:: + + Create a Zip archive that contains the contents of the latest + commit on the current branch. Note that the output format is + inferred by the extension of the output file. + +`git archive -o latest.tar --prefix=build/ --add-file=configure --prefix= HEAD`:: + + Creates a tar archive that contains the contents of the latest + commit on the current branch with no prefix and the untracked + file 'configure' with the prefix 'build/'. + +`git config tar.tar.xz.command "xz -c"`:: + + Configure a "tar.xz" format for making LZMA-compressed tarfiles. + You can use it specifying `--format=tar.xz`, or by creating an + output file like `-o foo.tar.xz`. + + +SEE ALSO +-------- +linkgit:gitattributes[5] + +GIT +--- +Part of the linkgit:git[1] suite |
