Customizing Your Prompt	Learn how to override theme defaults with a custom configuration file.

Overriding Theme Defaults

Oh My Posh lets you personalize your prompt by combining built-in themes with custom settings. If a theme (e.g., star.omp.json) doesn’t fully suit you, you can override its defaults using a custom config file.

How It Works

1. Themes are loaded from the themes/ directory or a built-in set.
2. A custom config file (e.g., ~/.myposh.omp.json) can override specific properties like colors, segments, or styles.
3. When you run oh-my-posh init or set $POSH_THEME, the custom file takes precedence.

Steps to Override a Theme

1. Pick a Base Theme:
   • Find a theme you like (e.g., themes/star.omp.json) in the repo or your local install (oh-my-posh get themes).
   • Copy it to a new file:

     cp ~/.poshthemes/star.omp.json ~/.myposh.omp.json
