backgrounding a running wget job

backgrounding a running wget job

[Gregory Nowak]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi all.

I have a running wget job, which I started interactively, without the
- -b flag, so I could look at the progress. However, I now need to put
the wget job into the background, so I can logout. Is there a safe way
to do this while it's downloading? I was hoping I can use screen here,
but after reviewing the screen man page, it looks like screen can
attach to, and detach from existing screen sessions, rather then a
simple wget running from bash on the console itself if that makes
sense. Am I wrong here, and can screen actually do what I want? Is
there another way to do what I want to do?

When I log back in, I'd like to be able to bring wget back into the
foreground again, so I can once more keep an eye, or should I say an
ear, on the progress. Any tips would be much appreciated. Thanks in
advance.

Greg

Greg,
I use screen all the time,
I just  start screen, start wget, and then exit my ssh client.

Hi.
If you want to do this process, type screen. start your wget job, hit control a then d log out, and when you want to bring your wget job up again, in the console type screen -x or -r respectivly.
personally, I use screen -x to bring my screen up, just because.

Thanks for the responses. Let me clarify my question though. From the
replies I'm reading, it seems the impression I've given people is that
I don't know how to use screen, and this I do know, at least well enough
to do what I've needed it for so far. My question concerning screen
was can I take a wget process already running in another standard
console, (I.E., no screen involved, just bash), and attach screen to
it without stopping it, or effecting its operation in anyway. As far
as I know, the answer to that question is no.

Anyway, I solved the problem by biting the bullet, hitting ctrl+c on
the wget job, launching screen, and starting the wget job over again
under screen this time, passing the -c flag to wget to continue a
partial download, and all seems to be working fine now. Then, I of
course detached from the screen session, and logged off.

Hi!

  In theory this could be possible: you have to change wget's process group 
id to same as one of your screened shells. Unfortunately i do not know any 
tool to do this.

  If you use bash you can put wget background witht
  ^Z, bg  wget
and  detach it from current shell with
disown wget

  but if the wget is outputting continuously this may now work. There is 
afaik no way to get process bakc to foreground.

Re: backgrounding a running wget job

[Tyler Littlefield]

this could be coded, though I don't know if I would be the one to do it. My
workload is sorta heavy, but I might be willing to give it a shot if someone
would explain it.

Thanks for the info. I didn't want to suspend the wget job with
ctrl+z, since I didn't know what that would do to the download. Yes,
the wget process would be suspended, and it would pick up right where
it left off. What about the tcp connection to the other system, that
would be reset as soon as wget got suspended and stopped responding,
wouldn't it? Yes, I know, in that case, wget would simply retry the
connection upon resuming, but still ...

Also, yes, wget was in fact outputting continuously, which is another
reason why I wanted to attach it to a screen session, in addition to
bringing it back into the foreground when I chose. Also thanks for the
introduction to the disown command, didn't know that existed.

Anyway, like I said, I bit the bullet, and have things working like I
want them now.

Greg
