Is there a command that will monitor a process for exiting (crash or 
normal exit) and
then execute another command based on the said process no longer being 
active?

Or is there a "wrapper" command that runs a process and when that 
process exists
due to crashing or just exiting normally) that another process can be run.

Thanks,

Jerry
