Can this be done using Applescript?

[EMTools]

Hi there !

I am helping to set up a workflow for our company using applescript. One of the things we need to do is copy large files (approx. 700 MB - 5 GB) across a dedicated 2 MB phoneline connection.

Here is the thing…We need to control how much data is copied per second. We don’t want to use the full 2MB bandwith because 1 MB of it is already being used for a live video stream. This stream must never be interupted. We are hoping to do approx 100 kb/s - 160 kb/s.

We know it will take long to transfer but this is what we need to do for now.

Can this “throttle” perhaps be done using a do shell script?

Any help would be much appreciated.

Kind Regards

Have a look at the curl man page.

And

–limit-rate
Specify the maximum transfer rate you want curl to use. This
feature is useful if you have a limited pipe and you’d like your
transfer not use your entire bandwidth.

          The  given speed is measured in bytes/second, unless a suffix is
          appended.  Appending 'k' or 'K' will count the number  as  kilo-
          bytes,  'm'  or  M' makes it megabytes while 'g' or 'G' makes it
          gigabytes. Examples: 200K, 3m and 1G.

          The given rate is the average speed, counted during  the  entire
          transfer. It means that curl might use higher transfer speeds in
          short bursts, but over time it uses no more than the given rate.

          If  you  are also using the -Y/--speed-limit option, that option
          will  take  precedence  and  might  cripple  the   rate-limiting
          slightly, to help keeping the speed-limit logic working.

          If this option is used several times, the last one will be used.

I am not sure if this can be used for sending??

Hi Mark ,

Thanks for the info. I have no experience with curl. What would a typical syntax line look like?

In our requirement we would probably “pull” instead of “push” so sending shouldn’t be a problem.

I’ll have a look at the curl man page

Thanks again.

It appears that we will be able to actually map the drive on the remote site machine directly using VPN. So it’s like working on our LAN.

Would I still use curl for this transfer ? If so then I think I’ve got what I need using curl.

or

Are there alternatives?

Kind regards

Just out of interest, is there a way to throttle “Finder” when performing copy functions?
