Beautiful !. Elegent and clean. (Although I still dont know why ">/dev/null"
wont do...)
I Tried this in /bin/csh on a HP-UX 7.0 system 9000/345 and got the most
interesting message
Reset tty pgrp from 391 to 366
Then a quick "Jobs" command gives
[2] -Broken pipe yes |
Another quick "Jobs" shows nothing.
a strings on /bin/csh shows
Reset tty pgrp from %d to %d
Just what is this trying to say? Am I supposed to change prgrp or is the shell
just telling me it has.
Which shell, the parent or the forked ":" ?.
