screen for starters

screen is a popular text based window manager, which allows
multiplexing several interactive shells in a single terminal.

To start a screen session is pretty simple:
(byobu as an alternative to screen can be used in ubuntu)

user@ubuntu:~$ screen

This starts a screen session with a particular process id(pid).
To resume/kill the screen session, this pid is used.

For people who would like to deal with names rather than pid numbers, a name can be associated with the screen session with:

+ user@ubuntu:~$ screen -S my_screen_name

Ctrl-a is the screen-control. All the screen related features is prefixed with ctrl-a.

+ Name the tab:
ctrl-a : title tab_name

+ creating a new tab:
ctrl-a c

+ shift between tabs:ctrl-a <tab_number>
ctrl-a <space>
ctrl-a p             (previous)
ctrl-a n             (next)

 

+ kill the tab
ctrl-a :kill


+ detach screen:
ctrl-a d
