I am attempting to grep the total system memory of a Solaris box with the (prtconf | grep Memory) command, and then user Reg expressions to gather the RAM amount but I received the error: Could not open pipe for prtconf. This should work, Any help would be appreciated.

#!/usr/local/bin/perl -w
use FileHandle;

$memcmd=`/usr/sbin/prtconf | grep Memory`;
$tmem = 0;
$tmem_idle = new FileHandle ("$memcmd") || die "Could not open pipe fo
+r prtconf: $!\n";
while (<$tmem_idle>) {
      if ( $_ =~ m/^.*\s+(\d+)\s+\d+$/ ) { $tmem = $1; }
}
close $tmem_idle;
$tmem_busy = $tmem;

# Just print the info!
print "The total Memory amount is: $tmem_busy";

exit 0;

O.K. -- syntax kills me again. Many thanks for the help.
