Shell confusion

[Dave Bolt IT Solutions]

Thanks to all the contributors to this subject.
I am pleased to say that I managed to work around the problems I was having, 
and understand the causes of the problems.
Of course, I also had to get to grips with vim, I'll be doing my own 
introductory document on that shortly. It's been 25 years since I last used 
a line editor and took a bit of searching to find the right basic 
information.
Anyway, if you contributed, consider your name listed here.
Thanks again.
Dave
