My sysadmin toolbox (Linux.com)
I'm a librarian by trade, and while this tool may be a little specialized for general sysadmin work, if you're a librarian who's ever had to deal with Machine-Readable Cataloging (MARC) records, then the MARC Record Translation Program (MRTP) is for you. MRTP will take a file of MARC records and turn them into legible, readable records that are editable by hand or with Perl. Comparable in some respects to MarcEdit, this program is more of a scripting program than a GUI-based app. It's really only useful for a specialized market, but if you need it, you need it."
