I want to create a script when I am checking if apmccctrl.sh is running & if it isn't running I want to be able to start it up and check again.
If the shell script is running I want to be able to return a status of "running" or number 1 for example.
If found it isn't running I want it to try and start it up and wait 60 seconds to then again check if it has started up successfully or not.
If failed again I want it to return "not running or 0 for example so we are able to alert on it.
Hope this makes it easier to explain.
I am using Putty version 0.63
This is what I have created so far but even if I shutdown the apmccctrl.sh I still get a return code of 1.

What I need to learn is how to use a script that launches background processes, and then kills those processes as needed.

shlock
SHLOCK(1) General Commands Manual SHLOCK(1)NAME
shlock - create lock files for use in shell scripts
SYNOPSIS
shlock -p pid -f name [ -b ] [ -u ] [ -c ]
DESCRIPTION
Shlock tries to create a lock file named name and write the process ID pid into it. If the file already exists, shlock will read the
process ID from the file and test to see if the process is currently running. If the process exists, then the file will not be created.
Shlock exits with a zero status if it was able to create the lock file, or non-zero if the file refers to currently-active process.
OPTIONS -b Process IDs are normally read and written in ASCII. If the ``-b'' flag is used, then they will be written as a binary int. For
compatibility with other systems, the ``-u'' flag is accepted as a synonym for ``-b'' since binary locks are used by many UUCP pack-
ages.
-c If the ``-c'' flag is used, then shlock will not create a lock file, but will instead use the file to see if the lock is held by
another program. If the lock is valid, the program will exit with a non-zero status; if the lock is not valid (i.e., invoking
shlock without the flag would have succeeded), then the program will exit with a zero status.
EXAMPLES
The following example shows how shlock would be used within a shell script:
LOCK=<pathrun in inn.conf>/LOCK.send
trap 'rm -f ${LOCK} ; exit 1' 1 2 3 15
if shlock -p $$ -f ${LOCK} ; then
# Do appropriate work
else
echo Locked by `cat ${LOCK}`
fi
BUGS
shlock does not assumed to be used under a number of lock/unlock environment in a short time. Namely, shlock should be used for an envi-
ronment like daily or hourly based job.
