sliceit.scpt

on run argv
  set input_file to POSIX file (item 1 of argv)
  set output_path to item 2 of argv

  -- make sure output folder exists
  do shell script "mkdir -p " & output_path

  -- drop input file on Slicy app
  tell application "Finder"
    activate
    open input_file using application file "Slicy.app" of folder "Applications" of startup disk
  end tell

  -- Save slices to output folder
  tell application "System Events"
    tell application process "Slicy"
      delay 5 -- might need to set this higher depending on PSD layers
      keystroke "s" using {command down} -- do save
      delay 1
      keystroke "g" using {shift down, command down} -- set output path with go to folder
      keystroke output_path
      keystroke return
      delay 1
      keystroke return
      delay 2
      keystroke "q" using {command down} -- quit

#!/bin/sh
osascript ~/bin/sliceit.scpt "$PWD/$1" "$PWD/$2"

Put files in ~/bin (if that is in your path)
