@lizuki Here are some basic screen commands from the tldr help page:

  - Show open screen sessions:
    screen -ls

  - Start a new named screen session:
    screen -S session_name

  - Reattach to an open screen:
    screen -r session_name

  - Detach from inside a screen:
    <Ctrl> + A, D

  - Kill the current screen session:
    <Ctrl> + A, K

Useful: Send text to a screen even if detached (except in version 5.0.0, it returns a buffer overflow instead):

screen -S <session_name> -X stuff <text>

For example, send "ls -l" to screen s1:

screen -S s1 -X stuff "ls -l\n"

Here \n adds a newline at the end, effectively pressing enter after a command.

While we're here, I might as well do the same for tmux. Again, some basic tmux commands from its tldr page:

  - Start a new session:
    tmux

  - Start a new named session:
    tmux new -s name

  - List existing sessions:
    tmux ls

  - Attach to the most recently used session:
    tmux attach

  - Detach from the current session (inside a tmux session):
    <Ctrl>-B d

  - Create a new window (inside a tmux session):
    <Ctrl>-B c

  - Switch between sessions and windows (inside a tmux session):
    <Ctrl>-B w

Some more cool commands:

  - Attach a specific session:
    tmux attach -t <session_name>

  - Split the session vertically:
    <Ctrl>-B %

  - Split the session horizontally:
    <Ctrl>-B "

  - Send text to a session, even if detached:
    tmux send -t <session_name> <text>

  - Send command to a session, even if detached:
    tmux send -t <session_name> <command> ENTER
    tmux send -t s1 "ls -l" ENTER

Finally, tmux will automatically complete partial commands. For example, instead of using

tmux attach-session -t <session_name>

You can shorten it like so:

tmux attach -t <session_name>

tmux a -t <session_name>

Of course, there is a lot more information on both of their manpages.
