Exclude "Permission denied" files for "ls -al"
 

Sometimes when I do "ls -al" I am given a list of files with Permission Denied messages. If I do "ls -al | grep -v 'Permission'" it'd still list them on the screen. Is there anyway to stop this?

I want to be able to do this ultimately but not when it keeps giving me these Permission Denied file names.
find . -user 'username' -exec rm -rf '{}'\;

Maybe dump the error messages to /dev/null (outer space!):
Of course, this will hide errors that you may be interested in too (it will toss all errors in the trash).

Well the question you have to ask yourself is where are the error messages being delivered to, remembering that a pipe by default delivers stdout to the stdin of the next command.

Ah thanks thought the pipe command sends everything (both stdout and error) to the next command.
