How to add bash auto completion in CentOS 8 Linux

by

In CentOS 8 Linux, you can add bash auto completion by installing the bash-completion package and enabling it in the .bashrc file. Here are the steps to set it up:

  1. Open a terminal window and log in as the root user or use the sudo command to run the following commands.
  2. Install the bash-completion package by running the following command:
yum install bash-completion
  1. Edit the .bashrc file by running the following command:
vi ~/.bashrc
  1. Add the following line to the end of the file:
source /etc/bash_completion
  1. Save and close the file by pressing Esc and then :wq
  2. Reload the .bashrc file by running the following command:
source ~/.bashrc

After completing these steps, you should have bash auto completion enabled in your terminal. You can now use the Tab key to automatically complete commands, file and directory names, and other options.

Please note, you may need to log out and log back in for the changes to take effect.
