use tmux as a “GUI” interface

November 16, 2019 Leave a comment

I have a console application that clears the screen, draws a table and updates it every second in an infinite loop (let’s call it Part A). If this application is started with a specific command-line parameter, then it starts in interactive mode (Part B). From Part B I can give some commands that control Part A. How could I display both Part A and Part B in the terminal?

You can do it with tmux. With tmuxp, it’s even simpler. Here is a config file called sample.yaml that you can load with “tmuxp load sample.yaml“.

session_name: main-pane-height
- layout: main-horizontal
    main-pane-height: 35
  - shell_command:
    - echo top pane
  - shell_command:
    - echo bottom pane
  window_name: Title Comes Here

This creates two panes and executes the specified commands in the panes. With this I could start Part A in the top pane, and Part B in the bottom pane.

number of lines and columns of your terminal

November 16, 2018 Leave a comment
$ tput lines
$ tput cols

Of course, the values depend on your own settings.

I found it in the script, which adds snowflakes to your terminal. Really cool.

In Nim, there are functions for these in the module terminal. See terminalWidth and terminalHeight.

reddit from the terminal

There is a command line interface for Reddit called “rtv” (reddit terminal viewer). It’s written in Python, so you can install it with pip.

Here is a short youtube video on how to use it.

open a terminal in a specified folder

From a script I want to launch a terminal that opens in a specified folder.

Thanks to #linux, I got two solutions:

A1) I use konsole, which has an option for this:

konsole --workdir /tmp

It will open a terminal in the /tmp directory.

A2) Change directory to the specified folder and launch the terminal:

cd /tmp; konsole

If you want to do it from a script, the idea remains the same.

B) If you want to execute a command automatically in the opening terminal, use this:

konsole -e mc

C) Set the title of Konsole to a specified text:

konsole -p tabtitle='NVIM server'

Terminator: a cross-platform terminal emulator with advanced features

April 9, 2011 Leave a comment

Terminator is a cross-platform GPL terminal emulator with advanced features.

I’ve been using konsole for years but I think I will switch to terminator.


  • Arrange terminals in a grid (see screenshot below)
  • Tabs
  • Highly configurable
  • Drag and drop re-ordering of terminals
  • Lots of keyboard shortcuts (see the keybindings section)
  • Save multiple layouts and profiles via GUI preferences editor



sudo add-apt-repository ppa:gnome-terminator
sudo apt-get update
sudo apt-get install terminator

My config file:

See my config file here. Its location is $HOME/.config/terminator/config (rename it to “config“).


Update (20110511)
I was using terminator for a month but today I switched back to konsole. Terminator is not bad but I find some things annoying. I also sent two questions / feature requests to the developers and got no answers, so I don’t know if it’s still developed. Konsole is not that fancy but works just fine.

Install ncurses

March 11, 2011 Leave a comment
sudo apt-get install libncurses5-dev libncursesw5-dev

If you want to compile a source code and you get the “curses.h: No such file or directory” error, then these are the packages you need to install.

Tip from here.
