About Using Tmux for Time-consuming Scripts on Remote Servers

Using tmux utility you can start some time-consuming command on a remote server and then leave it running there while closing the SSH connection.

Install it to remote Ubuntu Linux server with:

$ apt-get install tmux

On that server, start a new bash window with:

$ tmux

Then start any time-consuming script or command.

While it's running, detach the window with:

Ctrl + b, d

Now you can log out or exit the SSH connection.

After a while, connect to the server and get back to long-running command with:

$ tmux attach

To exit the tmux window completely type:

$ exit
