LINUX-VERSION(1)                       General Commands Manual                      LINUX-VERSION(1)

NAME
       linux-version - operate on Linux kernel version strings

SYNOPSIS


       linux-version compare VERSION1 OP VERSION2

       linux-version sort [--reverse] [VERSION1 VERSION2 ...]

       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 pack‐
       age version strings and should not be compared as such or as arbitrary strings.

       compare VERSION1 OP VERSION2
              Compare version strings, where OP is a binary operator. linux-version returns  success
              (zero  result)  if  the specified condition is satisfied, and failure (nonzero result)
              otherwise.  The valid operators are: lt le eq ne ge gt

       sort [--reverse] [VERSION1 VERSION2 ...]
              Sort the given version strings and print them in order from lowest 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 included 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 low‐
              est version.

       list [--paths]
              List kernel versions installed in the customary location.  If the --paths option, show
              the corresponding path for each version.
