Re: [MacPerl] hotfolder mechanism

[Axel Rose <rose@sj.com> (by way of Vicki Brown)]

Thanks for pointing me to the relatively new "folder action"
scripts. There are examples available in the "Scripts"
folder within the system folder.

First I did not consider them for my task because I didn't
like the setup of a folder action starting a MacPerl script,
which in turn is scripting StuffIt and finally moving
stuffed files to the destination folder with MacPerl.

The example scripts employ a check for file type of "bzy". I
haven't heard of this one before.

Some other considerations: A Mac sharing it's volumes via
AppleShare gets awfully slowly if I let him poll a
hotfolder, run StuffIt and move files around. Transfering
files dropped from 800kBytes/s to 40k/s. Users might think
the serving Mac is frozen. While the polling script executs
sleep() my impression is that this costs too much
performance. Does anybody know a better method for idling
around in MacPerl?


Again many thanks for following me


Cheers,
Axel
