Maybe you're looking for a streamlined experience on Ubuntu, akin to Windows' Win+R command dialog. The good news is that with a bit of scripting in your terminal, you can achieve just that! In this guide, we'll walk through the challenge and provide a solution that lets you open a terminal emulator and interact with it only once. The Problem: One-Time Interaction with the Terminal When you attempt to create a script for Ubuntu that opens a terminal emulator and allows users to input a command once before closing, you might run into a few hurdles: Lack of Auto-Completion: As you type commands, having the ability to auto-complete can significantly improve efficiency and user-friendliness. Recognition of .bashrc and .bash_aliases: By default, the terminal may not recognize certain custom configurations and aliases you've set up in your .bashrc or .bash_aliases files. The Current Approach Your initial attempt using: [[See Video to Reveal this Text or Code Snippet]] gives a basic interaction, but unfortunately, it does not address the two key issues mentioned above. The Solution: Setting Up the Bash Session Correctly Fear not! There’s a way to create a temporary interactive bash session that resolves these issues. You can modify your command to ensure both auto-completion works and your aliases are recognized. Step-by-Step Instructions Follow these steps to set up your temporary interactive bash session: Open your terminal. Type the following command: [[See Video to Reveal this Text or Code Snippet]] Breakdown of the Command gnome-terminal: This initiates the terminal emulator. -- bash: This tells the terminal to open a new bash shell. --rcfile <(...): Using a process substitution, we read your original .bashrc file and add the command PROMPT_COMMAND="PROMPT_COMMAND=exit". This modification ensures the terminal will exit after executing the first command. cat ~/.bashrc: This part retrieves your existing configuration, maintaining any custom aliases or functions. echo 'PROMPT_COMMAND="PROMPT_COMMAND=exit"': This command ensures that the terminal session closes automatically after the command runs. Conclusion Now you have a simple and effective way to execute a one-time command in Ubuntu’s terminal that supports auto-completion and recognizes your predefined aliases. This method simplifies the environment for users who may only need to run a quick command without keeping the terminal open unnecessarily. Next time you're in need of a temporary interactive command prompt, remember this handy trick! Happy scripting!
