What it does

Ohmyzsh customizes your terminal experience with themes, plugins, and settings, making it easier to work with your command line interface.

Install / run

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

When to use it

•You spend a significant amount of time working in the terminal and want to personalize your experience.
•You're looking for a way to automate repetitive tasks or workflows in your terminal.
•You want to make your terminal more visually appealing and easier to navigate.

Quick start

1After installation, open a new terminal window to see the changes take effect.
2Edit your ~/.zshrc file to customize your theme, plugins, and settings.
3Run the command 'omz update' to update ohmyzsh to the latest version.
4Add a new plugin by adding the plugin name to the plugins array in your ~/.zshrc file, for example 'plugins=(git osx zsh-syntax-highlighting)'
5Apply your changes by running 'source ~/.zshrc' or restarting your terminal.

Ready-to-paste prompt

To see a list of available themes, run the command 'ls ~/ohmyzsh/themes' and then set your theme in ~/.zshrc with 'ZSH_THEME="robbyrussell"'

Heads up: Ohmyzsh requires zsh to be installed on your system, so if you're using a different shell, you'll need to switch to zsh before installing ohmyzsh.
