Custom Bash Prompt in Intellij

Recently I wanted to change the prompt in the terminal when using IntelliJ.  I have a development prompt that I like to use whenever I am developing and wanted IntelliJ to also use it.

If you just point the terminal in IntelliJ to a script that sets your prompt, it will not work.  It simply runs that script and fails to open the terminal.  There are a few solutions to the problem if you are using bash (thanks thrig!).

1. Method 1: Running bash --rcfile mycustomrc will read whatever customizations you need from the given file.  It may also be helpful to use the --login or --noprofile flags depending on whether you do or do not want the mycustomrc to mix with the standard shell settings.
2. Method 2: Use an environmental flag to determine whether or not to load the custom settings in the standard shell settings files.
3. Method 3: Feed the custom shell configuration into a new bash process, then interact with it. See e.g. feed, feed.1, zcomppoke, zcomppoke.1 for this pattern in action.

I choose method #1 since it was the simplest for what I wanted, and did not require me to add an environment variable before it would work.

To make this work, I had to set the terminal prompt as follows:

/bin/bash --rcfile ~/.dotfiles/dev_bashrc

That was all there is to it, the dev_bashrc is in my dotfiles repo on GitHub.  It simply changes the prompt and loads as normal.
