Well, for starters, redhat-release only exists on redhat. it's also only a file, so might lie or be missing.
More distributions have /etc/release but it's not impossible they won't, or be incorrect.
/proc/version is more general but only a Linux thing as far as I know.
uname exists almost everywhere.

Hello, I need some help to correct my algorithm steps to sum a number. I am confused... please input some steps
Example:
Let's say a number 5.
Now we can get a list of numbers: 1, 2, 3, 4 (less than 5 in sorted order).
so the sum could be: 1+4; 2+3 ( 1+1+1+1+1 or 1+2+2 is not a solution).

linux::distribution
Linux::Distribution(3pm) User Contributed Perl Documentation Linux::Distribution(3pm)
NAME
Linux::Distribution - Perl extension to detect on which Linux distribution we are running.
SYNOPSIS
use Linux::Distribution qw(distribution_name distribution_version);
if(my $distro = distribution_name) {
my $version = distribution_version();
print "you are running $distro, version $version
";
} else {
print "distribution unknown
";
}
Or else do it OO:
use Linux::Distribution qw(distribution_name distribution_version);
my $linux = Linux::Distribution->new;
if(my $distro = $linux->distribution_name()) {
my $version = $linux->distribution_version();
print "you are running $distro, version $version
";
} else {
print "distribution unknown
";
}
DESCRIPTION
This is a simple module that tries to guess on what linux distribution we are running by looking for release's files in /etc. It now looks
for 'lsb-release' first as that should be the most correct and adds ubuntu support. Secondly, it will look for the distro specific files.
It currently recognizes slackware, debian, suse, fedora, redhat, turbolinux, yellowdog, knoppix, mandrake, conectiva, immunix, tinysofa,
va-linux, trustix, adamantix, yoper, arch-linux, libranet, gentoo, ubuntu, scientific, oracle enterprise linux and redflag.
It has function to get the version for debian, suse, fedora, redhat, gentoo, slackware, scientific, oracle enterprise linux, redflag and
ubuntu(lsb). People running unsupported distro's are greatly encouraged to submit patches :-)
EXPORT
None by default.
TODO
Add the capability of recognize the version of the distribution for all recognized distributions.
