Hi Thanks for the replies.
But i have been getting the same error.
So in my lookup i have mentioned as
Code:
echo /a/b/c/box/$(ls -rt /a/b/c/box|grep -i cef |tail -1)

and to get this above stmt to execute and assign to ftf is :
Code:
ftf=$(eval $(cat $file_path | grep -i $STR | cut -d '*' -f4))

This is working for me....but as you can see in my lookup file i have hardcoded the path.
So the issue remains I have to parametrize this value.

Which could be :
Code:
echo $(ls -rt $BOX |grep -i cef |tail -1)

But this $BOX don't seem to resolve.I even tried \$BOX to resolve.
But it doesnt seem to resolve the value.

Can anyone please suggest some solution.

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
