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.
