Bash completion is a powerful tool that significantly enhances your command-line experience. It allows you to auto-complete commands, options, and file names, saving time and reducing errors.
Install Bash Completion
The first step in adding bash completion to Debian 12 is to install the necessary package. Fortunately, Debian 12 includes bash completion in its official repositories, making it easy to install.
Open a terminal window. You can do this by pressing Ctrl + Alt + T or by searching for “Terminal” in your application menu.
Before installing any new packages, it’s a good practice to update your package list to ensure you’re getting the latest version. Run the following command:
sudo apt update
Once your package list is up-to-date, install the bash-completion package by running:
sudo apt install bash-completion
Verify the Installation: To ensure bash completion has been installed successfully, you can check the version:
dpkg -l | grep bash-completion
Enable Bash Completion
After installing the package, you need to ensure that bash completion is enabled in your shell. Bash completion should be automatically enabled in Debian, but it’s always good to check. Open your .bashrc file in a text editor:
nano ~/.bashrc
Add the Completion Script: Scroll through the file to see if the following lines are present:
# enable bash completion in interactive shells if ! shopt -oq posix; then if [ -f /usr/share/bash-completion/bash_completion ]; then . /usr/share/bash-completion/bash_completion elif [ -f /etc/bash_completion ]; then . /etc/bash_completion fi fi
If these lines are not present, add them to the end of the file.
Apply Changes: After making changes to .bashrc, apply them by sourcing the file:
source ~/.bashrc
Test Bash Completion
With bash completion installed and enabled, it’s time to test it.
1.Try a Command: Open a new terminal session and start typing a command you often use, like sudo apt. Press Tab twice to see the possible completions.
2.Explore Options: Try different commands and options. For instance, start typing sudo apt-get and press Tab. Bash will show you all the possible options, such as install, remove, or update.
