multipipe - supervise a pipeline of commands

multipipe [ directory ]

multipipe starts one supervise process for each subdirectory of the current directory. multipipe skips subdirectory names starting with dots. Each supervised processes is piped a copy of standard input sent to multipipe.

Every five seconds, multipipe checks for subdirectories again. If it sees a new subdirectory, it starts a new supervise process. If a subdirectory is removed, it closes the pipe to that supervise process. Directory named supervise or with names starting with a period are ignored.

If multipipe is given a command-line argument, it switches to that directory when it starts.

If multipipe is sent either the INT, QUIT, or the TERM signal, or it reaches end of file on standard input, it runs svc -dx on each command to shut it down, and waits for it to exit.

Exits 0 when all the commands are shut down.
