A lightweight (single file), cross-compatible (bash v3/v4, MacOS, Linux) bash prompt.

• Single file installation to keep it simple
• Works on MacOS and Linux (and probably others)
• Multiple color themes that can be switched in the same session
• Text input colorized to emphasize commands being executed
• Easy to modify contents of prompt

The included multi-line prompt has the following items:

• Time of day in HH:MM format
• Duration of previous command, colorized to indicate success or failure
• Username, colorized to indicate root or non-root user
• Hostname
• Current path trimmed to three directories (configurable)
• Current git branch if in a git repo
• Number of running/sleeping jobs

Download .bash_prompt to your $HOME directory. Select a theme from the list below or create your own. Then add the following block of code to your $HOME/.bashrc or $HOME/.bash_profile, which will ensure the prompt is loaded only during an interactive session.

if [[ -n $PS1 && -f ~/.bash_prompt ]]; then
  . ~/.bash_prompt
  ps1_dark_theme  # Choose your theme here
fi

Here are the included themes. To switch the theme in your current session, type the name of a theme.

Note: your colors will vary depending on the ANSI color definitions in your terminal emulator. I have included my MacOS Terminal theme in the misc directory if you want to mimic this exact look. That color theme is based on Will Stone's Plastic theme for VSCode.

Here is a screenshot of the bash prompt in the VSCode's integrated terminal.
