As long as you use bash instead of tcsh, yes.

bash -c ' output = `some_command 2>&1` ; echo "$output" '

Notice than nowdays we can use $(some_command 2>&1) instead of the
backquotes, which is nice because you can nest them:

bash -c ' msg=$(printf "%dnd result = %s" $(( 1 * 2 * 3 * 7 )) "$(echo "Do not panic")" ) ; echo "$msg" '
42nd result = Do not panic


Or use chsh to switch to bash:
