NAME
linux-version - operate on Linux kernel version strings
SYNOPSIS
linux-version compare KERNEL-VER-1 OP KERNEL-VER-2
linux-version sort [--reverse] [KERNEL-VER-1 KERNEL-VER-2 ...]
linux-version list [--paths]
DESCRIPTION
linux-version operates on Linux kernel version strings as reported by
uname -r and used in file and directory names. These version strings do
not follow the same rules as Debian package version strings and should
not be compared as such or as arbitrary strings.
compare KERNEL-VER-1 OP KERNEL-VER-2
Compare version strings, where OP is a binary operator.
linux-version returns success (zero result) if the specified con-
dition is satisfied, and failure (nonzero result) otherwise. The
valid operators are: lt le eq ne ge gt
sort [--reverse] [KERNEL-VER-1 KERNEL-VER-2 ...]
Sort the given version strings and print them in order from low-
est to highest. If the --reverse option is used, print them in
order from highest to lowest.
If no version strings are given as arguments, the version strings
will instead be read from standard input, one per line. They may
be suffixed by arbitrary text after a space, which will be in-
cluded in the output. This means that, for example:
linux-version list --paths | linux-version sort --reverse
will list the installed versions and corresponding paths in order
from highest to lowest version.
list [--paths]
List kernel versions installed in the customary location. If the
--paths option, show the corresponding path for each version.
