Question:

I forgot how to redirect stderr in Unix.

Answer:

Actually its neither of the above.
1 = std out file descriptor
2 = std err file descriptor

so the following redirects stderr to a file named 'junk'

rm backup.zip 2>junk

and the following redirects both stdout and stderr into a file named junk

rm backup.zip 1>junk 2>&1

the >& says to use the same file used by '1'
