In my remote terminal I have put in background the following running Linux process
dd if=/dev/sda3 | gzip -1 - | pv | ssh user@.rsync.net dd of=image.gz
in
- Ctrl+Z
bg
disown pid1 pid2 pid3 pid4
(4pids
since they are 4 commands in sequence where each pipes to the next one)
Then (without having left current SSH terminal session yet) I brought it in foreground with fg
and I see it running.
1. How do I exit fg
and send the process (job) back to its background ?
I am afraid that Ctrl+Z will make a second
background or job for the already backgrounded process or Ctrl+C will end both fg
screen and the process itself.
2. Also would it be possible to run fg
for the same job
again and bring it to foreground if I disconnect from remote terminal and reopen it after a while?
You
disown
it and then you're able tofg
? What shell is it? – Kamil Maciorowski – 2018-06-05T13:01:04.840Yes I can
fg
it because I haven't still disconnected from the very same SSH session where I started thebg
of the process. Second question has to do with that. |GNU bash, version 4.1.2(2)-release (x86_64-redhat-linux-gnu)
– Cadmos – 2018-06-05T13:03:42.410Strange. This is very different from Bash 4.3.48 and what I know about jobs. I
disown
a whole job (even if giving just one PID that belongs to the pipe of the job). After that it's no longer on the job list, so I cannotfg
it. Your experience is different so there must be something I don't know. – Kamil Maciorowski – 2018-06-05T15:21:26.223
