![]() Then it will work with many types of terminal and not just the one that you have hardwired. Generate them with tput setaf and tput setab and use command substitution to place the result into your PS1 shell variable. The other programs are not hardwiring control sequences, which is why they work. If you look carefully at your UXTerm screenshot you will see that that is exactly what UXTerm has in fact done, set a low-numbered colour and turned boldface on, just as your prompt asked. Your prompt is trying to set colours 8 to 15 by setting colours 0–7 instead, and turning on boldface (with SGR 1).(The rest of the gibberish specifies that it sets colours 16 and upwards in response to SGR 38:5 and SGR 48:5, with the faulty separators.) Your terminal sets colours 8 to 15 in response to SGR 90–97 and SGR 100–107, which is what all the gibberish in the setaf and setab actually does.It has hardcoded SGR control sequences for changing colour, and it has hardcoded the wrong ones, for another terminal type. ![]() Your prompt is not correct for your terminal type.

This shows the changes are done, successfully. For that, run the same command again but this time you will see the Asterik (*) in front of the Terminal you have selected. Once you are done with the previous steps, it’s time to check whether the default Terminal has been changed and set to the new one or not. Check whether you have changed the default Shell or not For example, to set Alacritty, we type – 1 and then press the Enter key. After that type it and hit the Enter key. What you have to do, is first find the “ Selection” number of the Terminal that you want to set as the default one. Press to keep the current choice, or type the selection number: (providing /usr/bin/x-terminal-emulator).Ģ /usr/bin/gnome-terminal.wrapper 40 manual mode ![]() sudo update-alternatives -config x-terminal-emulatorĪs you run the above command, you will get the list of all existing Terminal-emulators with a provision to select any of them.įor example: There are 7 choices for the alternative x-terminal-emulator Run the given command to change and select the default Ubuntu or Debian Terminal. It is because this utility is responsible for setting up default applications in Ubuntu or Debian.Ĭoming to the main topic, how to use this utility? For that, open your system’s already installed Terminal. It is not limited to the Command line app, we can use it for browsers and other applications as well. We can use this utility to switch between the installed Terminal applications on our system to make any of them the default one. In such cases, an inbuilt utility of our Linux system, called update-alternatives comes into play. For example, Ubuntu offers Gnome Terminal but now you have installed the Terminator or Alacritty and want any of them set as the default one. Well, to change the default Ubuntu Terminal and set some other, we need to have at least one more Terminal emulator app apart from the one which comes with the system. ![]() ![]() Check whether you have changed the default Shell or not Steps to set default Terminal in Ubuntu or Debian Linux ![]()
