Use Shell Script in Apple Script (in FileMaker)

Does anyone know how to change the syntax of this shell script to use it in a calculated AppleScript in FileMaker?

#!/bin/bash

# change to internet plug-ins directory

cd /Library/Internet\ Plug-Ins/

if [ -e "AdobePDFViewer.plugin" ]

then

# if viewer exists move it to disabled plug-ins directory

# (create directory if needed)

mkdir -p Disabled\ Plug-Ins

mv AdobePDFViewer.plugin Disabled\ Plug-Ins/

echo "plug-in has been moved"

else

echo "nothing to be done"

fi

The AppleScript should probably look something like this:

List (

"set fileMoved to false";

"try";

"do shell script (.....)"

"set fileMoved to true";

"end try";

"tell me to set cell \"result\" of layout \"Developer_Settings\" to fileMoved"

)

Thanks in advance for your help!!
