From: RolandRB on
This is a reminder that on my Roland's SAS Macros web site you will
find comprehensive teaching material for learning Unix. Not only
learning Unix commands but learning how to write shell scripts, once
you are familiar with the Unix commands. I wrote this especially for
SAS programmers so as long as you are a moderately competent SAS
programmer then you will not be overwhelmed by any of the terminology.
You will learn it one easy step at a time. The Unix teaching material
started out as the official documentation for the Unix part of the of
the clinical reporting system (later expanded and named Spectre-
Clinical) that I wrote for a small biostats department in Munich. The
Unix teaching material is in the form of an ebook. You have to
download it and unzip it into the recommended directory structure for
all the links to work.

It will take about three months to become competent with Unix
commands, be able to write shell scripts and be able to design your
own scripts to run a clinical reporting system. I am quite certain
that for SAS programmers, the teaching materials I have are better
than anything else you can find on the Internet or can read in a book
(I was a science teacher for a few years). Not only is all the
information you need there (and no more) in easy steps to learn, but
it teaches you how to think with Unix. The latter is now almost absent
from other teaching materials you will find and yet it is very
important for the design of a maintainable suite of shell scripts. The
approach is quite different to the way you will used to using for SAS
programming. Three months is a lot of learning and you will not be
able to shortcut it if you want to be able to design a set of clinical
reporting system scripts so my advice is to not start down this path
unless you need to. But you can stop short at just being competent
with Unix commands and being able to write very simple shell scripts
after a month if you are happy with that.

All this material can be downloaded from the following URL and I will
remind people once again that you can download an entire clinical
reporting system (Spectre-Clinical) for free from my web site. The
Spectre-Clinical reporting system has been used for several years at a
small CRO in southern Germany so it is a well-tried and tested, robust
application.

I know that people find it difficult to believe that one person can
design and write a robust clinical reporting system plus all the
system scripts that run it (in fact I would laugh at the suggestion
that anyone could do this) and that such a system could actually work
properly, but if you look at my CV you will see that it is packed with
the sort of experience that makes it possible for me to do this.
