Unfortunately, the grep -w option is not included in the standards, so it might or might not work on your system. (This is one of the reasons why you should always tell us what operating system you're using when you start a thread here.)

If grep on your system supports the -w option, it is a great choice for what you are trying to do. Otherwise, please tell us what operating system you are using and show us some representative sample data so we can make alternative suggestions to help you.

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
