docker groupAt my work, after I had installed Docker I
added myself to the docker group as follows:
sudo usermod -aG docker ${USER}

su - ${USER}
To get a new shell in which I had been added to the docker group.
I verified this using:
groups
And indeed as expected the group docker was listed.

In general, I urge you to work through the Perl documentation’s tutorials on references, lists of lists, the data structures cookbook, and the FAQs on array and hash manipulation. Then dip into the various list-processing modules (especially the included List::Util and CPAN’s List::SomeUtils) for ready-made functions for common operations. You’ll find a wealth of techniques for creating, managing, and processing the data structures that your programs need.
