Yes. To send stderr to file log and not stdout do

foo 2> log

where foo is your command producing output & error. Naturally this will will not work for csh-type shells.

sh - write to stderr

*Tags*: redirect to stderr

echo "aaa" >&2

if you have a Bourne-based shell. If you have C-shell, well, I think you're probably kinda stuck (redirecting anything other than stdout from C-shell is notoriously hard).
