I read about "watch" command in the mpx paper (*) and thought
it's interesting. The paper mentions the commandline:
watch fig1.pic | pic | troff | proof
and the pipe line runs whenever fig1.pic is modified.
Does anyone have a similar program in his pocket?

I'm thinking of writing a file server (watchfs) which will serve:
/n/watch/ctl
/n/watch/data/a.c
/n/watch/data/b.c
Whenever a.c and b.c are changed, a text will appear on the ctl file.
Thus, you can do something like:
% while(){read /n/watch/ctl; mk}
How's this idea?
