I am trying to create a progressbar which shows how long it takes to download a youtube movie to my desktop.
I use this for the download process:
do shell script "curl -L " & quoted form of downloadURL & " -o " & POSIX path of outputFile & “> /dev/null 2>&1 & echo $!”
“curl -L " & quoted form of downloadURL = download location of the youtube movie
& POSIX path of outputFile = location on my drive
/dev/null 2>&1 & echo $!” = shell script job runs in background, so script continous immediatly & gives a code (pid) back
I found out that Curl has its own progress code but can’t find anything more than:
PROGRESS METER
The progress meter exists to show a user that something actually is
happening. The different fields in the output have the following meaning:
% Total % Received % Xferd Average Speed Time Curr.
Dload Upload Total Current Left Speed
0 151M 0 38608 0 0 9406 0 4:41:43 0:00:04 4:41:39 9287
From left-to-right:
% - percentage completed of the whole transfer
Total - total size of the whole expected transfer
% - percentage completed of the download
Received - currently downloaded amount of bytes
% - percentage completed of the upload
Xferd - currently uploaded amount of bytes
Average Speed
Dload - the average transfer speed of the download
Average Speed
Upload - the average transfer speed of the upload
Time Total - expected time to complete the operation
Time Current - time passed since the invoke
Time Left - expected time left to completion
Curr.Speed - the average transfer speed the last 5 seconds (the first
5 seconds of a transfer is based on less time of course.)
The -# option will display a totally different progress bar that doesn’t
need much explanation!
Well it does 
Anyone any experience or can help me out with some nice tricks ??
