Bash configuration

Bash can be configured to the user’s liking through the .bashrc file. The “rc” in .bashrc stands for “run commands,” which is exactly what .bashrc is. This file contains a series of commands that will be run whenever a new shell is started. There are a number of options that can be configured via the .bashrc file.

Usage

To configure bash to your liking, create a .bashrc file in your home directory (if it does not exist already) and add the commands you’d like to be run whenever you start a new shell. As mentioned previously, there are numerous options that can be configured via .bashrc, but here are a couple common ones:

  • Aliases – through the use of the alias command, the user can define aliases for commands. For example, a user can define alias ll='ls -la' to quickly list all of a directory’s contents in long format without having to type out the full command.
  • Prompt customization – through exporting environment variables, the user can customize their shell prompt to their liking. The possibilities for prompt customization are numerous and outside the scope of a basic tutorial, but the article on the Arch Linux wiki below offers more information on prompt customization.
