If you have started a job on one of the Linux compute servers, you will probably want to monitor how it is getting on.
Another concern might be that the job continues to run after you have disconnected from the computer.
You need to be able to start a job, disconnect, wake up the next day, log in, and see progress on the job.
If you can do everything from the command line, I recommend using screen or, its newer replacement, tmux.
I use screen - use "man screen" to find all the gory details, or there is online help at https://linuxize.com/post/how-to-use-linux-screen/ or https://www.howtogeek.com/662422/how-to-use-linuxs-screen-command/
Basically, you type "screen" - and then do your stuff within screen. To detach (leaving screen and everything inside it running) type Ctrl-A D and when you log in again, to re-attach type screen -dr.
If you have a graphical session, VNC is the best way forward - I have another article on VNC - please find that on the left.
