9 lsb_release [OPTION]...
10
12 FSG lsb_release v2.0 prints certain LSB (Linux Standard Base) and Dis‐
13 tribution information.
14 With no OPTION specified defaults to -v.
16
18 -v, --version
19 Display the version of the LSB specification against which the
21 distribution is compliant.
22 -i, --id
24 Display the string id of the distributor.
26 -d, --description
28 Display the single line text description of the distribution.
30 -r, --release
32 Display the release number of the distribution.
34 -c, --codename
36 Display the codename according to the distribution release.
38 -a, --all
40 Display all of the above information.
42 -s, --short
44 Use short output format for information requested by other op‐
46 tions (or version if none).
47 -h, --help
49 Display this message.
51
53 If the installation is LSB compliant, the "/etc/lsb-release" file
54 should contain the LSB_VERSION field. The value of the field should be
55 a colon separated list of supported module versions indicating the LSB
56 specification modules to which the installation is compliant. If the
57 installation is not compliant, the above field should not be present.
58 Optional fields are DISTRIB_ID, DISTRIB_RELEASE, DISTRIB_CODENAME, DIS‐
60 TRIB_DESCRIPTION and can be used to override information which is
61 parsed from the "/etc/distrib-release" file.
62 If the "/etc/lsb-release.d" directory exists, it is searched for file‐
64 names which are taken as additional module-version strings to add to
65 LSB_VERSION.
66 The "/etc/distrib-release" file contains a description line which is
68 parsed to get information (especially on currently non-LSB compliant
69 systems).
70 The required line style is:
72 "Distributor release x.x (Codename)"
73 Where Distributor can be a couple of words, but then concatenated (i.e.
75 Linux Foo BarLinux Linux -> FooBarLinux),
76 x.x starts with a digit followed by any non-blank characters, Codename
77 will also be concatenated (blanks cleanup only).
78 release may not be used as a keyword in DISTRIB_DESCRIPTION if you
80 don't want to override "/etc/distrib-release" data.
81 Notice: To support the Debian distributions' lack of information (see
83 "/etc/debian_version" file) some have been directly added into the
84 lsb_release script.
85
87 If the "/etc/lsb-release" file contains:
88 LSB_VERSION="core-2.0-ia64:core-2.0-noarch"
90 DISTRIB_DESCRIPTION="I enjoy using my distrib"
91 and the "/etc/lsb-release.d" directory contains:
93 graphics-2.0-ia64 graphics-2.0-noarch
95 and the "/etc/foobar-release" file contains:
97 My Linux Distrib release 1.0RC4 (TryIt)
99 Then the results of various options will be:
101 $ ./lsb_release --all
103 LSB Version: core-2.0-ia64:core-2.0-noarch:graphics-2.0-ia64:graph‐
104 ics-2.0-noarch
105 Distributor ID: MyDistrib
106 Description: I enjoy using my distrib
107 Release: 1.0RC4
108 Codename: TryIt
109 $ ./lsb_release -a -s
111 1.0 MyDistrib "I enjoy using my distrib" 1.0RC4 TryIt
112 If the "/etc/lsb-release" file is absent (indicating this is not an LSB
114 compliant distribution), the result will be:
115 $ ./lsb_release -a
117 LSB Version: n/a
118 Distributor ID: MyDistrib
119 Description: My Linux Distrib release 1.0RC4 (TryIt)
120 Release: 1.0RC4
121 Codename: TryIt
