Automatically update outdated pip3 packages with bash scripts

I have a bash script to automatically update pip3 packages:

It is one line script:

pip3 list --outdated | cut -d' ' -f1 | xargs pip3 install --upgrade

and it has always worked.

Now (maybe after the upgrade to Ubuntu 18.04) it is not working anymore apparently because of a wrong usage of pip3 install.

What is wrong with the script?

Looks like headers of the pip3 list are causing failure in installation of package. You can trim those header lines by using tail.

pip3 list --outdated | cut -d' '  -f1 | tail -n+3 | xargs pip3 install --upgrade

tail -n+3 removes the header and boundary line which only gives package names to xargs.
