Lists useful scripts using common Unix and Linux tools. Most of these scripts are done in Ubuntu using the bash shell.
If you want the scripts to run automatically read up on cron and articles on adapting scripts to crons.
This area should also include general tips for adapting to crons and when necessary also versions of the scripts modified for crons.
Also, I note unstructured real world examples here too prefixed by "Real World -". These also make good contest ideas for a scripting contest.
