Add a Custom Function

Add the following function to your profile:

# Custom function to ensure the correct `thefuck` executable is used
thefuck() {
    # Save the current PythonIOEncoding
    TF_PYTHONIOENCODING=$PYTHONIOENCODING

    # Set environment variables for `thefuck`
    export TF_SHELL=bash
    export TF_ALIAS=fuck
    export TF_SHELL_ALIASES=$(alias)
    export TF_HISTORY=$(fc -ln -10)
    export PYTHONIOENCODING=utf-8

    # Run `thefuck` from the specific virtual environment with arguments
    TF_CMD=$(
        ~/.pyenv/versions/3.11.4/envs/thefuck-venv/bin/thefuck "$@"
    ) && eval "$TF_CMD"

    # Clean up environment variables
    unset TF_HISTORY
    export PYTHONIOENCODING=$TF_PYTHONIOENCODING

    # Add the command to history
    history -s "$TF_CMD"
}
