How to display the contents of a gzip/gz file

Problem: You have a plain text file that has been compressed with the gzip command, and you'd like to display the file contents with the Unix/Linux cat or more commands.

Solution: Instead of using the cat or more commands, use their equivalents for working with gz files, the zcat and zmore commands.

In this tutorial I take a quick look at the gzip and gunzip file compression utilities, along with their companion tools you may not have known about: zcat, zgrep, and zmore.
