GNU Screen
If you would like to know about tmux
, an alternative, click here.
GNU Screen allows you to run and seperate multiple login sessions within a seperate terminal window.
This program is also useful for dealing with multiple programs from the terminal and seperating programs
from the session that started the program, making it possible so remote processes continue running even when
the user has disconnected from the SSH connection. In our case, we can use this program to keep an instance of
weechat
running, even when we exit the session. This is useful as we can read previous IRC messages
without losing context/history from disconnecting connection, or switching between different devices.
