Re: still not catching error

You are testing the exit status of the system call, not the exit status of
the rsh call which is in $?.
You need

$systemstatus=system(...);
$rshstatus=$?;

  I took out the exec and placed system.  But even though
  work.pl doesn't
  exist on the remote system, still getting no error.  Help!
 
  if (system(rsh $plant /u1/bin/forkit '/u1/bin/work.pl')  0)
{
  excep( $!\n);
}

 The exit status of rsh is 0 if it was able to connect to the remote
 system. It doesn't return the exit status of the command being run.

From the docs for system():

   ...The return value is the exit status of the program
   as returned by the wait call.  To get the actual
   exit value divide by 256.

So he *is* testing the rsh exit status (at least 0 vs non-zero). 
The problem is that rsh does not return the exit status of the 
command it is running, which is what the OP is trying to check. 
$? will not help him with that.

Try

$result = `rsh $plant /u1/bin/forkit '/u1/bin/work.pl'`;

print $result;

You are storing the output of the rsh... command into the variable. You can
now run a regex on that to check for success/failure.

I don't know what the output should be but as an example...

$result = `rsh $plant /u1/bin/forkit '/u1/bin/work.pl'`;

if ($result =~ /worked/i) {
print Yep, that worked\n;
} else {
print Ooops. Something went wrong: $result;
}
