Update all packages using pip on Windows

This is the easier way to upgrade packages by using pip in conjunction with Windows PowerShell. Open your command shell and enter the below command. This will upgrade all packages system-wide to the latest or newer version available in the Python Package Index (PyPI).

pip freeze | %{$_.split('==')[0]} | %{pip install --upgrade $_}

Update all packages using pip on Linux

Linux provides a number of ways to use pip in order to upgrade python packages. This includes two ways using grep and awk.

• Use grep to upgrade packages – The grep is to skip editable (“-e”) package definitions, and the -n1 flag for xargs that prevents stopping everything, if updating one package fails.

pip3 list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip3 install -U

• Use awk to upgrade packages – The below command first lists all outdated packages, then fetches the first column and converts the multiline result from cut into a single-line, and forms a space-separated list. It then skips header lines, fetches the first column and takes 1 argument from the pipe left of it, and at last passes it to the command to upgrade the list of packages.

pip3 list -o | cut -f1 -d' ' | tr " " "\n" | awk '{if(NR>=3)print)' | cut -d' ' -f1 | xargs -n1 pip3 install -U
