I have an AppleScript which involves the user selecting a folder for images to be exported to (from Aperture). Later I need to run a shell script on the images in that folder. I had help at https://discussions.apple.com/thread/3012302 to get the shell script running. Currently Aperture exports the images but the script runs with an error


error "No file specified" number 1


suggesting I haven't said which folder to use.


So I believe I need to "tell FInder" the location of the folder chosen by System Events. If so how do I go about passing the name and location of my 'exportFolder' to application Finder? Or do you think something else is causing the error?


Script below, many thanks!


-- Creating a new filename by making Version Name  from the IPTC Headline and Filename (with hypens where spaces exist). The Aperture Version Name is used to create the file's name on export. Once exported the Aperture Version Name is reset to its original.


tell application "System Events"

          set exportFolder to (choose folder with prompt "Choose an export folder")

end tell



tell application "Aperture"

          set theSel to (get selection)

          if theSel is {} then

                    error "Please select an image or two!."


                    repeat with theImg in theSel


  -- Creating a new Aperture Version Name which will become the exported file's filename.


                              tell theImg

                                        set headline to (get value of IPTC tag "Headline" of theImg)

                                        set AppleScript's text item delimiters to " "

                                        set theTextItems to text items of headline

                                        set AppleScript's text item delimiters to "-"

                                        set headline to theTextItems as string

                                        set AppleScript's text item delimiters to {""}

                                        set objectName to (get value of IPTC tag "ObjectName" of theImg)

                                        set newVersion to (headline & "-" & objectName) as string

                                        set name of theImg to newVersion

                              end tell

                    repeat with theImg in theSel

                    end repeat

    Just to clarify the above - the script does export the image from Aperture to the chosen folder. The ExifTool shell script does not run.

    Looks like you just got your variables mixed up in the ExifTool shell script.  In your repeat loop, theFiles is a list of the files in your folder, while eachFile is the individual item you need to pass to the shell (you can't get the POSIX path of the list).

    In addition to Red's (correct) analysis, you're also missing a space in the exiftool command parameters:


              do shell script "/usr/bin/exiftool -overwrite_original -Photoshop:CopyrightFlag='True' -Photoshop:URL='http://davidgordon.co.uk/'" & quoted form of POSIX path of theFiles


    Note that you're appending the POSIX path of the file (or, as per Red's note, eachFile) directly after the 'Photoshop:URL' parameter. Since there's no space the shell will interpret these two elements as one and you'll end up with something like:




    which is guaranteed to fail.


    The solution is simple - trivial, even... include a space between the Photoshop:URL parameter and the path, like:


              do shell script "/usr/bin/exiftool -overwrite_original -Photoshop:CopyrightFlag='True' -Photoshop:URL='http://davidgordon.co.uk/' " & quoted form of POSIX path of eachFile


    (note the space after the quoted URL, and before the appended path)
