Screen!
See "man screen". It lets you start a shell session (optionally with a
distinctive session name) and detach from it. You can reconnect at any
time.
I routinely do this for downloads, OS updates, long running hand-started
daemons, etc.
In fact, I do it enough to use a wrapper script "scr":

which makes naming and use by name very easy:
scr FOO
makes new session named FOO. A plain:
scr
lists the sessions (like "screen -ls", but sorted and more readable).
BTW, you should also look at the "at" command for once off jobs.
But screen is more likely what you will find useful.
Cheers,
