I'd never seen Unix before until I came on this course. It was quite daunting at first but the instructor led us through logging in and then demonstrated the shell as a command line interpretor. By the end of the course I was hooked. Jim Gilbert

What has Pete Doherty from the Baby Shambles and Kate Moss got to do with daemons? Not likely to forget it when it's explained so well like that. Euan Smith

I had only seen a few features of the shell and I was quite impressed with them. But when you see the shell as a totally integrated entity, it was mind blowing. When it's explained well, the shell is the ultimate challenge. I now see its significance as a productivity tool. Tessa Gates

I like Vince's detailed, but step by step approach to learning about the shell. Once you realise its potential, almost anything is possible. Commands, options and arguments just hook into the shell's power. Brian Todd

Vince's sense of humour and understanding of working practices made this a real pleasure. I'm not sure if I believed he had a student called NV Ram. But the way he described it, I guess anything is possible. Khalid Udin

I'll never forget how to implement the for loop using command subsitution - for tabby in `cat basket` - Genius Vince. Kelly Jones

Vince explained brilliantly just why Unix is so quirky. There had to be a good reason and I feel better knowing. It used to be something that drove me mad. Liam Turner
