Hi,
just tried this
> ls -l /etc | less
Ctrl-Z
> ls -l /etc | less
[1] + Stopped ls -l /etc | less
> jobs
[1] + Stopped ls -l /etc | less
> fg
ls -l /etc | less
... now I'm missing the terminal output of the less command, a short
check shows
Ctrl-C
> tty
/dev/pts/0
> ps x | grep pts/0
9273 pts/0 S 1:02 ksh
9297 pts/0 T 0:42 less
9344 pts/0 R+ 0:00 ps x
9345 pts/0 S+ 0:00 grep --color=auto pts/0
that is that fg seems not to reenable the less command. Now
trying to reenable the less by sending SIGCONT shows:
> killall -CONT less
[1] + Stopped (SIGTTOU) ls -l /etc | less
... it seems that the tty output of less is stopped for
a for background process (ksh?).
