Discarding all output -- including stderr messages.
$ ls > /dev/null 2>&1
Or sending all output to a file
$ someprog > /tmp/file 2>&1
Sometimes, find displays a lot of errors when searching through
directories that the user doesn't have access to. To discard
error messages "stderr", which is normally file descripter "2"
work the following:
$ find / -iname 'stuff' 2>/dev/null
or to pipe results elsewhere
$ find / -iname 'stuff' > /tmp/results_of_find 2>/dev/null
