Hmmm... piping cats. Not a good sign.

UNIX commands are documented everywhere - the web, your server, you colleagues, etc. Try looking up what "cat", "grep", "cut", "tar" etc do, they are all pretty basic commands and easy to understand. Google can help or from your UNIX server's command line, type "man" for manual pages and then the command. For example:

Code: Select all

man cat
