|
If I use Putty on a Windows box to shell in (using SSH) to my Gentoo box at home, will an emerge I start - continue if I close Putty?
For example, I want to kick off a long KDE compile from work, so I shell in using Putty - then I want to exit Putty but have the emerge continue.
Is there a way to this?
thx |

No, it will not.
What you are really looking for is screen.
This program is extremely easy to use, and probably the single most useful utility that I have ever found for Linux administration. Here is what screen does in a nutshell:
When you run it, it starts a new shell, running in a virtual terminal, with your current teminal attached to it as a display. If your current terminal, say Putty, dies, the virtual terminal continues to run.
You can re-connect to a screen virtual terminal from anywhere: ssh, Xterm, tty.
To start a screen session, just type
To detach from the terminal, type Ctrl-A D.
To reattach to the screen (presuming you have only a single screen session running, type:
That is the absolute minimum that you need to know to get started.
There are many other commands and features that you may find helpful. You can start additional shells (or windows, in screen's parlance) from within any given screen session by typing Ctrl-A C. You can switch between these windows with various commands, such as Ctrl-A [space]. VERY NICE to be able to have multiple shells running from within a single Putty window.
I use screen to do all my emerging. I can start a merge on a server at work, and re-attach via SSH at home. I can even start a merge from the command prompt on my laptop, detach. Start X, and re-attach to the merge in an Xterm.
Just a few of the endless possibilities with this wonderful program.

you could also 'nohup' it. man nohup.
btw, nohup seems to not nohup if you exit out of your su, but if you just close the window instead of typing exit it carries on. |

Hey, I've run into the problem that sometimes screens will die for no apparent reason or reasons that I didn't spot yet in the docu... So in those cases, I can't tell if the job I set a box to under screen has finished or not.
Anybody know if screens "go bad" after some hours/days?
