How to run something even after logging out?


I know this may seem a dumb question but I am not really good at memorizing commands. I've read this before but I can't remember where I read it. What command should I type in so that the process will continue even after I log out? For example, I ssh on certain machine and would like to download something using the wget. After I logout, I want to continue downloading as long as the machine is up. Is that possible? How will I do it? Thanks.

Personally I use the screen command to do such things. It is sort of like VNC for console in that you can disconnect from a screen, let it do its thing, and then reconnect from someplace else. Check out man screen for the details on how to use it.

append & at the end to put it in background. disown will tell shell not to terminate program on your logout. This works in recent shells. Or use nohup.

you could run the command in background by appending a & after the command as in
this will continue running even if you logout.

I think if you put & at the end, it will still stop when you logout. & just makes it so you can continue using the same terminal session. I think what you want is $nohup <command> &

(nohup = no hangup, i think)
