What is Bash

Before learning what the bash profile on Mac is, it's necessary to know what Bash is first. Bash is a Unix shell and command language for the GNU operating system.

Bash has been used as the default login shell for most Linux distributions. It is also available for the Windows platform. In addition, Bash was also the default shell in macOS Mojave and earlier. Until the release of macOS Catalina, Apple changes the default shell to Zsh and Bash still remains available as an alternative shell.

What is bash_profile on Mac

In simple words, bash_profile is a configuration file for the Bash shell, which is a hidden file in your Mac's user directory. The bash profile on Mac has loaded before Terminal loads your shell environment and contains all the startup configuration and preferences for your command-line interface. Within it, you can change your Terminal prompt, change the colors of text, add aliases to functions you use all the time, and so much more.

The bash profile on Mac is an incredibly powerful tool that can make the Terminal app infinitely easier and quicker to use. It can improve your efficiency, help you avoid time-wasting errors, and just look really pretty on your screen.

  1. Open a plain text editor i.e. TextEdit.
  2. Press Command + O to open the file.
  3. Move to your home directory.

  5. Select .bash_profile, fix your problem and save it accordingly.

Alternatively, you can use the following simple command line to open and edit the bash_profile:open -a TextEdit.app ~/.bash_profile
