推荐答案

有两种方法可以做到这一点，但最简洁的方法是使用

There's a couple of ways of doing this but the neatest way is to use screen. This lets you create a session which lives perminently on the machine and you can simply reconnect to to check on the progress of your long running process.

如果您不想使用 screen ，则可以使用 nohup ，这使您可以运行以下任务:

If you don't wish to use screen you can use nohup this allows you to run a task like:

nohup mytask&

您的任务现在将在后台运行，并且在注销后仍将保留，但是与 screen 不同，您无法再次控制它.

Your task will now run in the background and will survive a log off, however there's no way to take control of it again, unlike with screen.
