Managing hook scripts (e.g., githooks(5)) shares many of the problems of
managing startup scripts. It is often useful for one hook script to
trigger multiple independent actions; for example, a Git post-receive
hook might want to send out email notifications, trigger an automated
build, etc. It would be nice to organize these actions as separate
scripts in a subdirectory, like
.git/
hooks/
post-receive
post-receive.d/
10-send-email-notification
20-trigger-build
...
Just the thing for run-parts!
But hook scripts are often fed some data on their stdin. For example,
the Git post-receive hook receives input that tells what references have
been changed, one line per reference. These data would be needed by
*each* of the sub-hook scripts for them to run correctly.
Therefore, it would be useful if there were an option to make run-parts
multiplex its stdin to *each* of the programs that it runs:
========= post-receive =================
#! /bin/sh
run-parts --mux-stdin -- post-receive.d
In the general case this would require the stdin to be written to a
temporary file, though in most real-world cases it would probably be
fine to cache the input in RAM.
It is not hard to write a separate utility with this functionality, but
it seems to me that it is a feature that would fit in well with what
run-parts already does.
