Update #Python modules #pip regularly #NotetoSelf

Krishnendu Paul -

We update our linux boxes almost regularly, so Debian/Ubuntu user like me run apt update && apt upgrade -y regularly. But, we miss updating python library regularly which breaks a lot of python modules or make them outdated.

Sharing 2 methods to do it easily with single liner.

1) 

Python 2.x:
pip list --outdated --format=freeze | grep -v '^-e' | cut -d = -f 1 | xargs -n1 pip install -U

Python 3.x:
pip3 list --outdated --format=freeze | grep -v '^-e' | cut -d = -f 1 | xargs -n1 pip3 install -U

2) 

pip3 install pipdate

then run pipdate command from shell.
