Checking status of engines using C-shell
I am relatively new to scripting. I am trying to develop a script that will
1. Source an executable file as an argument to the script that sets up the environment
2. Run a command "stat" that gives the status of 5 Engines running on the system
3. Check the status of the 5 Engines as either "Active" or "Not Found"
4. Compare the status of all 5 Engines
if all "Active" exit 0
if some "Active" & some "Not Found" exit 1
if all "Not found" exit 2

I have to write this script in C-Shell. Currently I have written the script for Step 1 & 2. For the rest of it I am thinking of storing the status of the 5 Engines in an array and then compare the value of array elements to decide on the exit status. What do experts say? I am also having a little difficulty using Arrays in C-shell. C-shell is not as straight forward as sh or ksh.

service

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

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service	runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
       working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script.  service passes COMMAND and OPTIONS to the init script unmodified.  All scripts should support at least the start and stop
       commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start  com-
       mand.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
