Finding stuff on linux

This is not directly MySQL related but I'm always having to find things on my Linux servers. Here are some useful example:

Finding a string value somewhere in a directory or sub directory in some file or multiple files:

grep -r "string to be searched" /path/to/dir


Finding large files on your linux machine:

du –cks ./* | sort -rn | head -11

Finding a file on a file system (the forward slash is the file system):

find / -name file_name

Finding things using the locate command (which relies on an index so it is faster)

updatedb <-- This will update the index file and can take a while on a large system, will need to be run after adding or changing a lot of files

locate file_name
