Linux Shell Script To Gather Basic System Info

Today, I thought we'd go for some lighter fare, so I put together another one of my simple shell scripts, specifically for Linux, that you can run on any system (although you do need some elevated privilege to get the correct information for a few of the commands) and print up a nicely formatted listing of system information (I tried to pick the stuff superiors tend to want to know).

If you run this in an SSH shell loop, it might just be a handy way to slap together a little system inventory to pacify the big guys ;) You can run it simply by calling it on the system you're running it on, like so:

./sysinfo.sh

Anyway, enjoy and best wishes. The work week is almost over :)
