Is there a script that can be written to halt the running programs cleanly too?
Sure, but it's a little tricky. You would first need to find out the PID of the agent you started. You could do this with the 'ps' command.
The PID in the above example is 13112. The tricky part is you don't want to leave any child/zombie processes that may have spawned from your script. If it does spawn extra processes then your script will have to find all the children and kill them in order. The last process you would kill would be 13112 since that is your original process. It's definitely doable though. Hope that makes sense.
** NOTE: Notice that I left a space after MyProgramN in my grep statement. This was done to ensure you had the right process for those cases when you might have MyProgram1 and MyProgram11 running. If you're looking for MyProgram1, then you want to make sure you don't accidentally catch MyProgram1N.

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
