Hi,
 I am using Perl on Linux server. I m writing a code which will tell
us the Linux distro with version. For this the command is

cat /etc/issue

which is common for all the distributions of linux. But the output
varies for different distributions.

For e.g.

SUSE

Welcome to openSUSE 11.0 (X86-64) - Kernel \r (\l).

REDHAT

Red Hat Enterprise Linux Server release 5 (Tikanga)

I am able to save the output in a string. Now I want a code or
function which will give me only the number from the string.
