Is there 'file indexer' for EVERY file on linux?

Question

I'm using winXP and openSUSE... On win, I have 'search everything' tool, which indexes every file in comp.. Is there a similar tool for linux.. It saves me much time... Thank you... http://www.voidtools.com/

Answer 1

For example you can use updatedb to create a directory index and search the index with locate.

Answer 2

find / -name "*.txt"

of course replacing *.txt with whatever you're looking for.
