If a static hostname is + set, and is valid (something other than localhost), then the + transient hostname is not used. + + Note that the pretty hostname has little restrictions on the characters and length used, while the static and + transient hostnames are limited to the usually accepted characters of Internet domain names, and 64 characters at + maximum (the latter being a Linux limitation). + + The static hostname is stored in + /etc/hostname, see + hostname5 + for more information. The pretty hostname, chassis type, and icon + name are stored in /etc/machine-info, see + machine-info5. + + Use + systemd-firstboot1 + to initialize the system hostname for mounted (but not booted) + system images. + + + + Commands + + The following commands are understood: + + + + status + + Show current system hostname and related information. If no command is specified, + this is the implied default. + + + + set-hostname NAME + + Set the system hostname to NAME. By default, this will alter the + pretty, the static, and the transient hostname alike; however, if one or more of , + , are used, only the selected hostnames are changed. If + the pretty hostname is being set, and static or transient are being set as well, the specified hostname will be + simplified in regards to the character set used before the latter are updated. This is done by removing special + characters and spaces. This ensures that the pretty and the static hostname are always closely related while + still following the validity rules of the specific name. This simplification of the hostname string is not done + if only the transient and/or static hostnames are set, and the pretty hostname is left untouched. + + Pass the empty string as the + hostname to reset the selected hostnames to their default + (usually localhost). + + + + set-icon-name NAME + + Set the system icon name to + NAME. The icon name is used by some + graphical applications to visualize this host. The icon name + should follow the Icon + Naming Specification. + + Pass an empty string to reset the icon name to the + default value, which is determined from chassis type (see + below) and possibly other parameters. + + + + set-chassis TYPE + + Set the chassis type to + TYPE. The chassis type is used by + some graphical applications to visualize the host or alter + user interaction. Currently, the following chassis types are + defined: + desktop, + laptop, + convertible, + server, + tablet, + handset, + watch, + embedded, + as well as the special chassis types + vm and + container for virtualized systems that lack + an immediate physical chassis. + + Pass an empty string to reset the chassis type to the + default value which is determined from the firmware and + possibly other parameters. + + + + + set-deployment ENVIRONMENT + + Set the deployment environment description. + ENVIRONMENT must be a single word + without any control characters. One of the following is + suggested: + development, + integration, + staging, + production. + + + Pass an empty string to reset to the default empty + value. + + + + + set-location LOCATION + + Set the location string for the system, if it + is known. LOCATION should be a + human-friendly, free-form string describing the physical + location of the system, if it is known and applicable. This + may be as generic as Berlin, Germany or as + specific as Left Rack, 2nd Shelf. + + Pass an empty string to reset to the default empty + value. + + + + + + + Options + + The following options are understood: + + + + + + Do not query the user for authentication for + privileged operations. + + + + + + + + If status is invoked (or no explicit command is given) and one of these + switches is specified, hostnamectl will print out just this selected hostname. + + If used with set-hostname, only the selected hostname(s) will be updated. When more + than one of these switches are specified, all the specified hostnames will be updated. + + + + + + + + + + + + Exit status + + On success, 0 is returned, a non-zero failure code + otherwise. + + + + See Also + + systemd1, + hostname1, + hostname5, + machine-info5, + systemctl1, + systemd-hostnamed.service8, + systemd-firstboot1 + + + + -- cgit v1.2.3
