Well done, Christian.
I hope you won't mind if I add one or two observations. I notice that
your script calls the 'current date' event from Standard Additions a
number of times, which carries an overhead. In this kind of situation,
it's more efficient to make one such call - and then extract the bits
that you want from a variable:
----------------------------
set currDate to current date (*don't coerce to a string here*)
set theTime to currDate's time string
-- etc...
set myDay to currDate's day
set myMonth to currDate's month
-- etc...
----------------------------
In addition, if you want your script to be portable, it's an idea to
think about the different date and time settings that a system might
have. For example, when I just ran the first few lines of your script,
the variable 'theGoodTime' returned a value of "52-24-am". In other
words, I'd lost the hour value - and was left with the minutes, seconds
and am/pm string. (No biggie if a script is purely for your own use -
but perhaps something to consider for the future...)
I see that in the end, you went for the shell script option - in which
case you could probably condense the above script a bit further (one
line - watch for wraps):
----------------------------
do shell script "curl " & "http://webcam.aet.ch/traffico/airolo_s.jpg";
& " -o " & quoted form of (POSIX path of (path to desktop) & "SBB
Webcam/") & (do shell script "date +%Y.%m.%d_%H-%M-%S.jpg")
----------------------------
(If anyone else wants to try this, create a folder on your desktop
named "SBB Webcam" first.)
