lsb_release - print distribution-specific information (minimal implementation).
This is a bare-bones version of the lsb_release command, implemented as a tiny POSIX shell script (less than 100 lines of commented code).
Instead of using LSB packages, this version of lsb_release uses the information in /etc/os-release and /usr/lib/os-release. Nevertheless, the output of this version is byte-for-byte compatible with the Python-based version provided by Debian and its derivatives.
Using this implementation it is possible to avoid installing Python in a base OS image while still retaining compatibility with older scripts that expect lsb_release to exist.
The program follows the usual GNU command line syntax, with long options starting with two dashes ("--"). A summary of options are included below.
- -h, --help
- Show a help message with a list of options and exit.
- -v, --version
- Show LSB modules this system supports.
- -i, --id
- Show distributor ID.
- -d, --description
- Show description of this distribution.
- -r, --release
- Show release number of this distribution.
- -c, --codename
- Show code name of this distribution.
- -a, --all
- Show all of the above information.
- -s, --short
- Show requested information in short format.
- Distribution-provided file with operating system identification data.
- Machine-specific file with operating system identification data. If present, /etc/os-release is read instead of /usr/lib/os-release.
