Come copiare gli elementi di una cartella su un automatore con montaggio su disco

Un modo per farlo è usare Automator:

1. crea un'azione cartella su / Volumi
2. attiva un oggetto Applescript o uno script di shell quando viene montata una nuova unità
3. fai la copia
4. prendi un caffè (opzionale).

Probabilmente vorrai raschiare l'output di system_profiler SPUSBDataType per assicurarti di non scherzare con i DMG.

Oooh, opzione 2 da overflow dello stack (copia / incolla come una citazione di blocco di seguito):

You can use launchd for that purpose. Launchd can be configured to automatically launch a program when a file path is modified.

For example the following launchd config plist will launch the program /usr/bin/logger when the desktop folder of my user account is modified:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>logger</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/bin/logger</string>
        <string>path modified</string>
    </array>
    <key>WatchPaths</key>
    <array>
        <string>/Users/sakra/Desktop/</string>
    </array>
</dict>
</plist>

To activate the config plist save it to the LaunchAgents folder in your Library folder as "logger.plist".

From the shell you can then use the command launchctl to activate the logger.plist by running:

$ launchctl load ~/Library/LaunchAgents/logger.plist

The desktop folder is now being monitored. Every time it is changed you should see an output in the system.log (use Console.app). To deactivate the logger.plist, run:

$ launchctl unload ~/Library/LaunchAgents/logger.plist

The configuration file above uses the WatchPaths option. Alternatively you can also use the QueueDirectories option. See the launchd man page for more information.
