exuse me, I didn't mention it as that was obvious to me with such a name.

what pswait does : it waits for some [usualy backgrounded] process to end before quiting. So for example you can wait for a specific [backgrounded] wget/ncftp downloads to finish or for a bunch of similar process to terminate before launching another command:

pswait httpd; backup.sh

here backup.sh will be launched after all httpd deamons exited.

pswait 10123; mail -s "picture processing terminated" me@home

if you want an email alerting that your job 10123 is done
This command is very usefull when working over slow networks links like dial up modems or when you have small number of process allowed on a system.
Update: just added pod documentation.
