Thanks to Bill for pointing me in the right direction. The solution turned
out to be very simple. Make sure that the $ in $2 is escaped.
remsh dhapp01 "who | awk '{print \$2}'"

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.

Subject: [HPADM] weird remsh/awk behavior
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.
