MacOS – How to import a .terminal file using the command line

Definitely scriptable with terminal commands.

/usr/libexec/PlistBuddy -c "Print" ~/Library/Preferences/com.apple.dock.plist

Shows you the actual configuration for the dock.

Within the above file you need to modify the "persistent-others" array if you want to create a "file" alias.

This is done the following way:

/usr/libexec/PlistBuddy -c "add:persistent-others:0 dict" ~/Library/Preferences/com.apple.dock.plist

If you want an application alias you will need to modify the "persistent-apps" array.

Once you make the changes and you are testing you need to do:

killall dock

to refresh the dock.

I would just do the whole thing at the command line as a shell script instead of using Automator to launch it. Put #!/bin/bash as the first line, and run it as

myscript.sh image*.png

where image*.png is your set of image files that you are apparently selecting in Automator?

If you need to run it on all files in a folder, that can be done too.

You can also test your script in automator using echo ${f%.*} instead of the commands themselves.
