I am not sure if my question is clear but I will explain as much as possible.
I am using ssh connection from my client laptop to Ubuntu, commanding very time comsuming job. During the time, terminal will print the results of the command.
tar -xvf filename.tar
takes an hour. I command in my laptop ssh connection and moved to the other place while connection is off. When reconnect to server, how would I know my last command is finished or not.
