simple terminal script to update all pip-packages that are installed (works perfectly inside PYENV ! )

pip_upgrade_all.sh

#!/bin/bash

# List outdated Python packages
outdated_packages=$(pip list --outdated)

if [ -z "$outdated_packages" ]; then
    echo "No outdated packages to upgrade."
else
    echo "Upgrading packages..."
    pip list --outdated --format=columns | tail -n +3 | cut -d" " -f1 | xargs -n1 pip install --upgrade
    echo "All packages upgraded."
fi
