Colorized tail

I was tailing a logfile and I wanted to colorize some specific keywords in it. I found Andreas Schamanek’s mycolorize which serves perfectly for the purpose. Download it and use it by doing $ tail logfile | ~/mycolorize color ‘regexp’ You can check additional examples and documentation on the website.

One-liner for downloading and extracting a tar.gz

I’m not the typical Linux one-linerd, but there are some that I find very useful.
