executing top on several computers

Hi

I'm waiting for the IT department to install Ganglia, and until that happens, I need to know the current load on 14 computers.

To do this, I'm trying to write a small script that output the top processes on each of the computers using top, but for some reason it doesn't work.

Code:
#!/usr/bin/ksh93
for i in {1..14}; do
  if (( $i < 10 ))
  then
   echo $i
   eval "ssh gotc10$i"
   eval "top -b -n 1 | head -n 8 | tail -n 1"
   eval "exit"
  else
   eval "gotc1$i"
   eval "top -b -n 1 | head -n 8 | tail -n 1"
   eval "exit"
  fi
done

What happens is that the script logs into the first machine, then does nothing.

Any input is highly appreciated.

Tobbe

GRUB-INSTALL(8) 							FSF							   GRUB-INSTALL(8)

NAME
grub-install - install GRUB on your drive SYNOPSIS
grub-install [OPTION] install_device DESCRIPTION
Install GRUB on your drive. -h, --help print this message and exit -v, --version print the version information and exit --root-directory=DIR install GRUB images under the directory DIR instead of the root directory --grub-shell=FILE use FILE as the grub shell --no-floppy do not probe any floppy drive --force-lba force GRUB to use LBA mode even for a buggy BIOS --recheck probe a device map even if it already exists INSTALL_DEVICE can be a GRUB device name or a system device filename. grub-install copies GRUB images into the DIR/boot directory specfied by --root-directory, and uses the grub shell to install grub into the boot sector. The grub source distribution carries this script to ease the installation of grub as a boot loader. In Suse Linux however, grub installa- tion is much better handled by Yast; use of this script is generally discouraged and therefore unsupported. Consequently, the script has been renamed to grub-install.unsupported. In order to (re-)install grub for the currently running system, simply use Yast. For an installation aiming at a differing system, the crafting of an appropriate device.map and grub shell script is strongly advised, e.g. "grub --batch --device-map=target-device.map < tar- get-grub.conf" SEE ALSO
The full documentation for grub-install is maintained as a Texinfo manual. If the info and grub-install programs are properly installed at your site, the command info grub-install should give you access to the complete manual. grub-install (GNU GRUB 0.97) May 2005 GRUB-INSTALL(8)
