find searches a directory for files

find /tmp -type d -print
tmp: directory to search
-type d: which files
-print: action to do with the files

There are my favourite find arguments!

-name/-iname

case insensitive
the filename! eg
-name '*.txt'

-path /-ipath

search the full path!
-path /home/*/*.go

-type [TYPE]

f: regular file
d: directory
1: symlink
and more!

-maxdepth NUM

only descend NUM levels when searching a directory.

-Size O

find empty files! Useful to find files you created by accident

-exec COMMAND

action: run COMMAND on every file found

-print0

print null-separated filenames
Use with xargs -O!

-delete

action: delete all files found

locate

The locate command searches a database of every file on your system.

good: faster than find
bad: can get out of date

$ sudo updatedb

updates the database
