locate

If you know the name ( or part of the name ) of the file you are looking for, use 'locate'. You need to install “findutils-locate-4.2.27-12” if this command is missing in your system. locate is an indexing based search program. You should run “updatedb” for proper functioning of locate. Usually this is done using a cron job. locate will be faster than the “find” command, since it is using the index created by updatedb for searching.

Beagle.

Beagle searches the files for the keywords you give. It is much like google desktop search. Yes, “grep” and do that. But the finest part about beagle is that it search almost any type of files. including your inbox, MP3 files, image files, chat log etc. I have found myself using google to search for something even if I'm sure it's some where in my home folder! Probabily I can save some traffic and time if I practice “beagling”.
