Heres the zgrep on my machine.

Just save this piece of code in your /usr/local/bin/zgrep and change the permission chmod +x /usr/local/bin/zgrep and use it

more /usr/local/bin/zgrep

gzip -cdfq | $grep $opt "$pat"
exit $?

If you lack zgrep you can do this:

zcat | grep STRING

7

don't forget about gzgrep. I use it all the time.

8

USE 'gzgrep' utility

The several times mentioned z* commands are often only available on Linux.
Anyway on most other Unices you should be able to resort to

$ gzip -dc zippedfile.gz | grep somepattern
