View The Content Of Files Without Comments In Bash

So I comment a lot of lines out in my /etc/hosts file. This usually means that I end up with a lot of cruft at the top of my file. And while I write comments into files and scripts here and there, I don’t always want to see them. So I can grep them out by piping the output of the file to grep as follows:

cat /etc/hosts | grep -v "^#"

You could also do the same, eliminating all lines that start with a “v” instead:

cat !$ | grep -v "^v"
