Hi, LRoberts:

What shell are you using that franklin52's parameter expansion did not work? I'm just curious.

Perharps the following command substitution is good enough:
Code:
/lcl/tools/bin/sshPing.pl "$(echo $remote_server | cut -d: -f1)" > /dev/null

Regards,
Alister

It just does not seem to work. It does not like my syntax.
This is how I am trying it...
Code:
#!/bin/sh
for remote_server in `ypcat osiunix_pods |cut -f 1-2 -d: | sort -t : -k 2`
do
remote=$(remote_server%:*)
/lcl/tools/bin/sshPing.pl $remote > /dev/null


Any ideas?
