sort -n | tail -1 is something I should have thought of... that is perfect solution..
thank you.

however, for my learning solution(as well as any bignners here who are in same boat as I am )..

here was my original script

#!/usr/bin/sh

z=0


grep -i something /dir/somefile |
sed 's/[^=]*=\([0-9]*\) [^ ].*/\1/g' |
while read a
do
if [ "$a" -gt "$z" ]
then
z=$a
else
:
fi
done
echo $z


IF I do aboe script, it does not work...

but if I do

grep -i something /dir/somefile | sed 's/[^=]*=\([0-9]*\) [^ ].*/\1/g' | filename

it works.. ??

sed's output here produces file that looks like

1
2
3
4 already.. so it should work.. but the way i am running through the script, it does not..

PWD(1)							    BSD General Commands Manual 						    PWD(1)

NAME
pwd -- return working directory name SYNOPSIS
pwd [-L | -P] DESCRIPTION
The pwd utility writes the absolute pathname of the current working directory to the standard output. Some shells may provide a builtin pwd command which is similar or identical to this utility. Consult the builtin(1) manual page. The options are as follows: -L Display the logical current working directory. -P Display the physical current working directory (all symbolic links resolved). If no options are specified, the -L option is assumed. ENVIRONMENT
Environment variables used by pwd: PWD Logical current working directory. EXIT STATUS
The pwd utility exits 0 on success, and >0 if an error occurs. SEE ALSO
builtin(1), cd(1), csh(1), sh(1), getcwd(3) STANDARDS
The pwd utility conforms to IEEE Std 1003.1-2001 (``POSIX.1''). BUGS
In csh(1) the command dirs is always faster because it is built into that shell. However, it can give a different answer in the rare case that the current directory or a containing directory was moved after the shell descended into it. The -L option does not work unless the PWD environment variable is exported by the shell. BSD
