Well the problem is I do not really need to echo it. I just need to use the string.

I tried....
Code:
/lcl/tools/bin/sshPing.pl $remote_server | sed 's/:.*//' > /dev/null

But that did not work.

Also tried...

Code:
/lcl/tools/bin/sshPing.pl ${remote_server%:*} > /dev/null

But I got... bad substitution

---------- Post updated at 07:47 AM ---------- Previous update was at 07:43 AM ----------

Also tried...

Code:
var=$remote_server
remote=${var%:*}
/lcl/tools/bin/sshPing.pl $remote > /dev/null

But I still get an error of bad sub.

Code:
/lcl/tools/bin/sshPing.pl $remote_server sed 's/:.*//' > /dev/null

cpurc

CPURC(8)						      System Manager's Manual							  CPURC(8)

NAME

       cpurc, termrc - boot script

SYNOPSIS

       cpurc

       termrc

DESCRIPTION

       After  the  kernel boots, it execs /boot (see root(3)), which in turn execs /$cputype/init.  Init(8) sets the $service environment variable
       to cpu or terminal, and then invokes the appropriate rc script to bring the system up.

       Based on the values of $sysname and $terminal these scripts start appropriate network processes and administrative daemons and enable swap-
       ping.  Cpurc sets /env/boottime to the time cpurc was executed and /env/NPROC to a value suitable for parallel compilation in mk(1).

       These files should be edited by local installations to reflect the configuration of their systems.

SOURCE

       /rc/bin/cpurc
       /rc/bin/termrc
