26 | \fBhostnamectl\fR [OPTIONS...] {COMMAND} | |
27 | .SH "DESCRIPTION" | |
28 | .PP | |
29 | \fBhostnamectl\fR | |
30 | may be used to query and change the system hostname and related settings\&. | |
31 | .PP | |
e842803a | 32 | This tool distinguishes three different hostnames: the high\-level "pretty" hostname which might include all kinds of special characters (e\&.g\&. "Lennart\*(Aqs Laptop"), the static hostname which is used to initialize the kernel hostname at boot (e\&.g\&. "lennarts\-laptop"), and the transient hostname which is a default received from network configuration\&. If a static hostname is set, and is valid (something other than localhost), then the transient hostname is not used\&. |

33 | .PP |
34 | Note that the pretty hostname has little restrictions on the characters used, while the static and transient hostnames are limited to the usually accepted characters of Internet domain names\&. | |
35 | .PP | |
36 | The static hostname is stored in | |
37 | /etc/hostname, see | |
38 | \fBhostname\fR(5) | |
39 | for more information\&. The pretty hostname, chassis type, and icon name are stored in | |
40 | /etc/machine\-info, see | |

5eef597e MP |
99 | Set the system hostname to |
100 | \fINAME\fR\&. By default, this will alter the pretty, the static, and the transient hostname alike; however, if one or more of | |
14228c0d MB |
101 | \fB\-\-static\fR, |
102 | \fB\-\-transient\fR, | |
103 | \fB\-\-pretty\fR | |
104 | 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 replacing spaces with | |
105 | "\-" | |
5eef597e MP |
106 | and removing special characters\&. 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 host names are set, and the pretty host name is left untouched\&. |
107 | .sp | |
108 | Pass the empty string | |
