I am currently running a program that ouputs parcer error information for each time step that is being run. The output goes into the terminal. I was wondering if there was any way to split a terminal in command line only ubuntu? Is there a command for this or any way to even do this?

Thanks

  • You mean you don't want the errors printed? ... add 2> /dev/null after the command. – Raffa Jul 01 '22 at 16:00

    Does this answer your question? What does 2>/dev/null mean? – Raffa Jul 01 '22 at 16:02

    Please [edit] your question and add more details: What do you mean with "terminal"? A terminal window on your graphical desktop? A (virtual) console, what you get with CTRL+ALT+F1 etc? A terminal connected to a serial port? How do you start the program that outputs error information? What do you mean with "split a terminal"? Do you want to see the output in one part of the screen while you work interactively in some other part? Maybe you can use a code block in your question to show how it should look like. – Bodo Jul 01 '22 at 16:24

These multiplexers help split the terminal window horizontally as well as vertically:

Tmux: is arguably one of the most used multiplexers out there. It is quite a reliable screen splitter that helps you split the Linux terminal window and adjust the window’s size. It is a keyboard-centric multiplexer. Which means all the function and customizations can be carried out right from the keyboard.

Install Tmux

 sudo apt install tmux

To run Tmux

 tmux new -s dev

Keyboard Shortcuts:

CTRL + B + % : Vertical Split.
CTRL + B + “ : Horizontal Split.
CTRL + B + O : Make other shell active.
CTRL + B + D : To Detach from tmux.
CTRL + B + ? : Help.

Screen: is a shell multiplexer. It is quite a reliable and capable shell multiplexer. You can split-screen both vertically and horizontally and detach and reattach the screen from the running session.

To install Screen

  sudo apt install screen

To Start Screen

  screen

Keyboard Shortcuts

CTRL + A + | : Vertical Split
CTRL + A + S : Horizontal Split
