Shorter Prompt on Terminal

Introduction

• To get shorter prompt on the linux terminal using zsh (Oh my Zsh), you can add the below config to the ~/.zshrc file.

1. Disable Conda’s Default Prompt Modification:
   • You need to configure Conda to not modify the prompt by itself. Add the following line to your .zshrc:

     conda config --set changeps1 False
     

2. Customize the Conda Prompt Modifier:
   • Define and use a custom function to display only the basename of the Conda environment directory.
3. Ensure the Custom Function is Integrated Correctly:
   • Modify your .zshrc to ensure your custom function is used correctly.

conda_prompt_modifier_short() {
    if [ -n "$CONDA_PREFIX" ]; then
        echo "($(basename "$CONDA_PREFIX")) "

}
