Oh My Bash is a delightful community-driven framework for managing your bash configuration, and an auto-update tool so that makes it easy to keep up with the latest updates from the community.

At the end of this blog post, your command line should look similar to the image below:

:inline

In the image:

  • Blue: indicates a non git based directory/subdirectory
  • Green: indicates a git based directory in sync with the remote
  • Orange: indicates a git based directory with changes to be applied

2sudo mv PowerlineSymbols.otf /usr/share/fonts/
3sudo fc-cache -vf

    1#echo $RANDOM_THEME
2#OSH_THEME="font"
3OSH_THEME="agnoster"

    NOTE: If the RANDOM_THEME is set, it will load a random theme each time oh-my-zsh is loaded.

  4. Reload the environment
