No, I'm suggesting that you type the command I gave to see how the awk
bit comes out. That's what ssh gets and what it's executing on the
remote machine.
To fix your problem, I would do:
ssh [EMAIL PROTECTED] "cat /etc/passwd | awk -F ':' '{ print \$1; }'"
or:
ssh [EMAIL PROTECTED] 'cat /etc/passwd | awk -F ":" "{ print \$1; }"'
(Actually I wouldn't use root at all, assuming a machine with shadow
passwords. But anyway.)
