Linux find command

basic syntax
$ find location comparison-criteria search-term

searches for files by their name

$ find ./test -name "abc.txt"
./test/abc.txt

wildcards

$ find ./test -name "*.php"
./test/subdir/how.php
./test/cool.php

all sub directories are searched recursively. So this is a very powerful way to find all files of a given extension.

Trying to search the "/" directory which is the root, would search the entire file system including mounted devices and network storage devices. So be careful. Of course you can press Ctrl + c anytime to stop the command.
