I've found a copy of the book "The Unix System" and I've had the paper "An Introduction to the UNIX Shell" for 20 years, but I thought I'd seen a slim book by S.R.Bourne called "The UNIX Shell" or something of the sort. However, Google, Bibliofind, etc have turned up nothing; has anyone seen this, or is my memory at fault once more? -- Pete Peter Turnbull Network Manager University of York
