    A couple of mentioned that I can remove the "" around the command that remsh
    is executing. That works, however, the awk is actually being done on the
    local machine then. This would be fine, except that what I'm really trying
    to do is kill some processes on a remote system:

    remsh <remote> "ps -fu <user> | grep <program> | grep -v grep | awk '{print
    $2}' | xargs kill -15"

    So, the entire command has to be on the remote system.

            Has anyone noticed the following remsh/awk behavior and if so, a
    workaround?

            Issuing who on the local machine works as expected.

            $ who
            dmullins pts/ta Nov 2 13:10
            npathil pts/tb Nov 3 16:30
            cdigrego pts/tc Nov 5 05:18

            Issuing who on the local machine and using awk to print out just the
    user
            name works as expected.

            $ who | awk '{print $1}'
            dmullins
            npathil
            cdigrego

            Using remsh to issue who on a remote machine works as expected.

            $ remsh dhapp01 "who"
            plpcd5 pts/ta Nov 5 09:21
            gpaveza pts/tc Nov 5 09:27

            Using remsh to issue a who on a remote machine and using awk to
    print out
            just the user name fails to work.
             
            $ remsh dhapp01 "who | awk '{print $1}'"
            sh: 1: Parameter not set.
