When I use bash to build pipelines, they sometimes don't finish but
instead some process remains running. Example:
$ tail -f -n 10000 log.txt | grep . | head -n 2
Almost instantly I get the expected two lines of output, but no prompt
back. I have to use ctrl-c. If I don't ctrl-c I can run pstree in
another terminal and see this:
This example is a poor one, as tail simply waits for a new line, when it
gets a new line it forwards it to the pipe and promptly receives a
SIGPIPE as grep is not there anymore.
I'll get back when I have distilled a better STC. If I can...
are you referring on something like SIGHUP on PTY closure ?
