I have thousands of .gz files all in one directory. I need to grep through them for the string Mouse::Handler, is the following the fastest (and most accurate) way to do this?
find . -name "*.gz" -exec zgrep -H 'Mouse::Handler' {} \;
Ideally I would also like to print out the line that I find this string on.
I'm running on a RHEL linux box.

Sometimes you need to search the contents of . gz files in your system. Unfortunately, grep doesn't work on compressed files. To overcome this, people usually advise to first uncompress the file(s), and then grep your text, after that finally re-compress your file(s)…
Solution: the zgrep command The Linux zgrep command works just like the grep command, except it works on text files that have been compressed with the gzip command. As you can see, using the zgrep command is much easier than using the three-step gunzip/grep gzip command I showed at the beginning of this article.
Awk doesn't read the . gz file. It still doesn't work.
You can search in parallel using
find . -name "*.gz" | xargs -n 1 -P NUM zgrep -H 'Mouse::Handler'
where NUM is around the number of cores you have.
