How to remove (base) from terminal prompt after updating conda

After updating miniconda3, whenever I open a terminal it shows "(base)" in front of my username and host.

In this answer post https://askubuntu.com/a/1113206/315699 it was suggested to use

conda config --set changeps1 False

To remove it.

But that would remove the indication for any conda environment. I would like to remove it only for the base one, so that I can maintain it always active and have access to its python and installed packages without having to always see this (base) taking up space.

Solution

  • Use the base env's activation hook

    For each env, any scripts in the etc/conda/activate.d directory will be executed post-activation (likewise etc/conda/deactivate.d scripts for deactivation). If you add a script to remove the (base), similar to @ewindes suggestion, you'll get the behavior you desire.

    I had to create this directory for base, which is just the root of your Anaconda/Miniconda folder. E.g.,

    mkdir -p miniconda3/etc/conda/activate.d

    Then made a simple file in there (e.g., remove_base_ps1.sh) with one line:

    PS1="$(echo "$PS1" | sed 's/(base) //')"

    If you are using zsh, use this instead.

    PROMPT=$(echo $PROMPT | sed 's/(base) //')

    Launching a new shell then does not show (base), and deactivating out of nested envs also takes care of the PS1 change.

    Note: You must add quotes around $PS1 if you want to preserve ending spaces.
