[sclug] Bash script help

[Neil Haughton]

To all those who wrote to help me,

Thanks for your contributions. I have learned a hell of a lot. Fro example
it has come as quite a surprise that unlike in other languages [ is not the
start of an expression, but is a command in its own right, but now I know
that my mistake makes perfect sense. The illumination on expansion (ie * )
was also not quite what I expected, but that too I now understand.

I suppose it reinforces the idea that a little knowledge is a dangerous
thing, and that before attempting anything else I should read up on it a bit
more beforehand! :-) RTFM, as they say.

Thanks to you all.

Neil.
