Thanks! It was a case of: I'd got a task I'd set myself, and I looked
for a tool to help.

I'm all for re-usability. And I like the idea of script files I can
keep handy to run with different inputs. Actually, I learned some
(very) basic C scripts on a Linux course I did years ago.

Since starting to learn grep and sed, I've discovered several tasks,
especially at work, where I could make use of them. By contrast, the
Windows XP dos prompt is clunky and its commands much weaker and so I
had already decided I would have to turn to learning batch files in
order to use dir and find efficiently.

That would be quite nice. As the perl talk will be techie, how about
tailoring the perl script to something that members are keenest on.
What I've heard in our meetings so far is that photo management,
display, search and batch manipulation are popular tasks. Could you
develop some scripts along those lines?

I remember we experimented with ImageMagick one evening last year with
great results, learning a bit about its associated name "Composite"
and its command "display" - that was fun.
