How to bring a background diamon to foreground

lieuquocdat · 07-17-2006, 10:24 PM

I am using Domino for linux, when systen starts iDomino also starts automatically in background. so I do not see running command lines. How can I do to bring a background Domino to foreground?

Well without knowing what system (distro) you are using, or what you mean by background (this could mean a lot of diffrent things), it's hard to give you an exact answer.

I alwaays use 'screen' if I want to send something away from the console I'm using, and recall it again to view the status. You can try and find which init script is starting the program, then change it to send it to a screen instead.

'screen' is nice because you can ssh into your box and pull the screen up at any time, then detach it again when you're done. Basic use is as follows:

SCREEN
<run app>
ctrl+a+d #detach the screen
screen -r # reatach the screen

'man screen' for more info.

I don't know that the following will work for domino or not but,
you can bring any job running in the background to foreground using this command

Code:

fg

Let me show you an example using shutdown command

Code:

root@Manish:~# shutdown -h 20:00 &
[1] 7445
root@Manish:~# jobs -l
[1]+  7445 Running                 shutdown -h 20:00 &
root@Manish:~# fg 1
shutdown -h 20:00

For more information, you can use fg manual

Code:

man fg

manishsingh4u, did you test your suggestions? On my MEPIS 3.3.2 system:

Code:

$ man fg
No manual entry for fg

However, there is considerable info about fg in the JOB CONTROL section of the bash man page (search terms: JOB CONTROL (case sensitive) or Job control refers).

Furthermore, (again on my system) fg works fine in the Konsole the job was started in, but not in any other. Did you forget "when system starts iDomino also starts automatically in background", which implies that it was started by a script & isn't running in a console at all.

OP, why do you want to bring it to the foreground?
Would killing it as part of the process be acceptable?

Sorry. my bad. I tested it on Mepis 3.4-3 and the output was same. I used fg a long while back so, perhaps I might have read the manual online.
Anyway, if u read my previous post carefully, u will notice that I have already mentioned that "I am not sure that it will work for his case", but this command can be used to bring jobs running in background to front. What u are saying is correct too that, it can't bring daemons running in the background to front.
Still, if my post created any confusions to u, I am sorry for that.

How can I use Screen command? I can not get help man about Screen on linux

chrisortiz · 07-19-2006, 08:55 PM

from reading the posts, i get the feeling that lieuquocdat wants to bring a daemon that loads on startup into the foreground. I don't know anyway to do that, but you can pico /var/log/dmsesg (slackware) or /var/lob/messages

Do you mean there was no man page for screen or you didn't understand it. If there is not man page for it, it's probably not installed on your system which means you will need to install it first.

I have re-read the thread & I think we need to know more to help you. Perhaps tell us why you want to "bring a background Domino to foreground". In other words, what's the underlying problem that prompted your Q?
Also, is there a difference between this "background Domino" & the "iDomino" (daemon) that "starts automatically in background" "when system starts". If the distinction is confusing, we can explore that.
If screen is not installed on your system & you want to read about it 1st, go here: http://man.linuxquestions.org/?query...ction=0&type=2. While there is no guarantee that it is exactly the same version you will get w/ your distro, it's a good start.
When you want to read a log file, less is a good alternative to pico or any other editor. If you haven't used it, check it out (man less ).

Well, why not kill it & restart it in the foreground?
