How we work

Configure Command Prompt

These days we use git in most of our projects. If we are using git then it's a good idea to know which branch we are working on. We can check what our current branch is but it would be much nicer if the command prompt displays the current branch automatically.

Second advantage is that when someone gets an error then usually they send a screenshot of the error. If the screenshot of the terminal,by default, display the directory and the branch name then that make debugging so much easier.

What I shell I'm using

Check this answer to find what shell you are using.

Custom Command Prompt for bash users

First check if you are using ~/.bash_profile or ~/.bashrc. You can find out if these files exist or not by executing following command.

1$ cat ~/.bashrc
2$ cat ~/.bash_profile
3$ cat ~/.zshrc

If you're using zsh, please install oh-my-zsh. Oh My Zsh is a framework to manage ZSH configuration and it by default comes with themes and helper functions.

If you're using bash, then open ~/.bashrc or ~/.bash_profile whichever of these file exists. Then at the bottom of that file paste the following content. Save the file and then open a new terminal.
