bash script to upgrade all outdated dependencies with python/pip

pip_upgrade_all_dependencies.sh

pip list --disable-pip-version-check --outdated --format=columns | tail -n +3 | awk '{print $1}' | xargs -n1 pip install -U || true
# explanations : 
# pip list --disable-pip-version-check --outdated --format=columns : print as a column format only the outdated dependencies, and suppress the warning if pip is outdated as it messes up the output
# tail -n +3 : keep only the lines after the first two
# awk '{print $1}' : keep only the first column
# xargs -n1 pip install -U || true : install each dependency, never fails via the || true (to use in a CI or script env)
