i want to get the differnce in minutes.
Example -
if a file was last updated 2 hours ago i want to get back 120.

you can use

ls -l yeh.log|sed "s/ */ /g"|cut -d" " -f6-8

to get the Update time of file

# 5  
but is there a way to compare it??
# 6  
A dirty perl script, not knowing if this is what you want:

#!/usr/bin/perl -w

$f1 = $ARGV[0];
$f2 = $ARGV[1];

print abs((stat($f1))[9] - (stat($f2))[9])/60, "\n";

Pass the two filenames as params
# 7  
i get strange results from that perl script.
when i run it on 2 files created with 1 hour different i get the result - 6681
