[Daniel Berlin <mail@xxxxxxxxxxxxxxxx>]

Hi everybody,
how about starting a collection of cool linux admin tips/commands/...
Like:

# To search all files in a directory and it's subdirectories do this:
grep -risnH 'PATTERN' *

or
#Â To copy a directory structure without changing atime/rights/owner/...
do this:
cd <SRC> && find ./ -print | cpio -padm <DEST>

Is there anybody out there with other cool
"make-the-admin-happy-with-one-line"
commands or similar tips ???

Greez,
daniel
