after wasting a couple of days exploring the great Mandrake educational software I'm finaly back on track (don't try 3d filemanagers its a farce).

• agrep - cool a fuzzy grep, a forgiving grep, grep that looks for aproximate matches, what more can you ask for,
• clamav in case you don't know about it already, this is the best Free anti virus, you use it to scan files going to windows machines of course ;-)
• binstat tool to give you statistics about your system binary files, very useful for stripping down a distro, tells you how many unused libraries you have, how many unstripped binaries, how many duplicate binaries and man pages etc.
• dnotify tool to execute certain commands when a directory's content is modified or accessed.
• emelfm2 about the only worthy GUI two pane filemanager, very simple, very minimal, I still prefer mc, it doesn't seem to support remote file systems at all.
