The following is a special collection of freeware tools for system administration written in Perl. They cover advanced topics for the experienced admin, and are a valuable addition to a senior admin's collection or those wishing to be a senior admin. Most are related to performance or fault prevention.
Note: These are freeware programs and have nothing at all to do with the respective Operating System vendors.

CDREWIND Rewind CDROMs before ejection. This should be performed before every ejection, otherwise discs can remain positioned incorrectly or can leave tracks behind in the drives. Full example here.
Code:$ cdrewind -v /vol/dev/aliases/cdrom0 CDROM rewound successfully. $ eject cdrom

l33t converts formal and confusing text into easily understandable l33t-speak. In the example below we show an original file, a l33t output, and a l33t output with all (-a) options. Full example.
