“Here is a selection of command-line tips that I’ve found useful
when working on Linux. The emphasis is on somewhat less-known
techniques that are generally important or useful to technical
users. It’s a bit long, and users certainly don’t need to know all
of them, but I’ve done my best to review that each item is worth
reading in terms of projected time savings, if you use Linux
heavily.“To get more information on a command mentioned, first try ‘man
‘. In some cases, you must install a package for this to work
— try aptitude or yum. If that fails, Google it.”
