Linux::KernelSort - Perl extension for sorting and comparing Linux kernel versions. The expected kernel version naming convention is the same naming convetion demonstrated by http://www.kernel.org. NOTE: Currently, only the 2.6.x series of kernels (including -rc's, -git's, and -mm's) are properly evaluated.
use Linux::KernelSort; my $kernel = new Linux::KernelSort; int $ret; my $version1 = "2.6.19"; my $version2 = "2.6.19-rc2-git7"; $ret = $kernel->compare($version1, $version2); if ($ret == 0) { print "$version1 and $version2 are the same version"; } elsif ($ret > 0) { print "$version1 is newer than $version2"; } else { print "$version1 is older than $version2"; } my @kernel_list = [ '2.6.15', '2.6.18', '2.6.18-rc2', '2.6.18-rc2-git2', '2.6.18-mm1', '2.6.18-rc2-mm1' ]; my @sorted_list = $kernel->sort($kernel_list); print "@sorted_list";
Linux::KernelSort is intended to sort a list of kernel versions into ascending order. It also provides the capability to compare two kernel versions and determine if one version is newer, older, or the same as the other version.
Purpose: Generate a ranking for a given kernel version Input: A string containing the kernel version which follows the proper naming convention demonstrated by http://www.kernel.org Return: Kernel ranking
Purpose: Compare two kernel versions Input: Strings ($kernel1, $kernel2) each containing a kernel version which follows the proper naming conventaion demonstrated by http://www.kernel.org Return -1 if $kernel1 < $kernel2 (ie $kernel1 is older than $kernel2) 0 if $kernel1 == $kernel2 (ie $kernel1 is the same version as $kernel2) 1 if $kernel1 > $kernel2 (ie $kernel1 is newer than $kernel2)
Purpose: Sort a list of kernel versions in ascending order. Uses shell sort algorithm. Input: Array of strings containing kernel versions which follows the proper naming convention demonstrated by http://www.kernel.org Return: Sorted array
