If I wanted to check this status out several times during the day, it would soon become tedious having to re-type this command every time. I know there are different ways, which save you from having to re-type commands, ie like searching your bash history, but that's one of the things I like about Linux, there is usually more than one way to achieve the same goal. Personally, I find it easier to create an alias for a given command sequence, if it's something I am likely to use on a regular basis. To see what alias commands your system already has set-up, you can simply type alias at the terminal prompt, which will give you a list of the current commands, and what shortcuts they are assigned to. Here you can see the word grep has been remapped to use grep in conjunction with the colour switch, which saves you having to specify this option on each grep command, effectively giving you auto colour highlighting by default.

Exported to a flash file (flv).
