after
=====

After the specified process dies, echo a string. (OpenBSD specific).

Usage
-----

	after [-h] [-v] [-p pid | -n process_name] -e string

The process to watch is specified `-p pid' or `-n process_name'. After this
process dies the string specified by `-e string' will be printed to standard

Notify yourself when your build is done:

	$ after -n gcc -e "build is done!"

The power of this simple tool can be observed when it is piped into other

	$ after -p 2027 -e "doas zzz" | sh
