find - Search the Live Tree

find - the workhorse

Scenario: "There's a rogue 4GB file somewhere under /var eating the disk - find it." This is a real ticket, and find is how you close it in seconds.

find walks a directory tree in real time and matches files against tests.

find  <where>   <test>
find  /var      -name '*.log'

Command	Finds
`find . -name report.txt`	Exact name under current dir
`find /etc -iname '*.conf'`	Case-insensitive, wildcard
`find /home -type d`	Directories only (`f` = files)
`find . -empty`	Empty files/dirs

$ find /etc -name '*.conf' | head -3
/etc/ssh/ssh_config
/etc/logrotate.conf
/etc/ld.so.conf

Tip: Quote your wildcards: find . -name '.log' (with quotes). Unquoted, the shell expands .log before find ever sees it, and you get confusing errors.
