At the last python workshop there was an interesting reaction: “I love the command line, it makes you feel like a hackerz, I wish I knew more about it”. So we did a class.

Several people came. Adrian wants to do some data science and it can really help to pipe a few text tools together to clean up a few data files. Noriko wanted to extract more power from the linux on her laptop. Jacintha (taking pictures) was really excited at the networking tools. Masa, the unix veteran, did not learn new things (except that on modern Ubuntu you can now delete non-empty folders without the -f flag) but came to help. Yves enjoyed teaching that group.
Oh, and the cat that joined us is actually named Unix. He enjoyed it too.
