Troubleshooting an Applescript Syntax Error

Question

I am trying to run the following applescript code I copied off a metafilter discussion:
#!/bin/bash
for word in $(cat ~/passwordlist.txt | grep -v "#")
do
echo $word
echo -n $word | hdiutil attach -mount required -encryption -stdinpass ~/foobar.dmg
if [[ $? = 0 ]]
then
echo "Password found!"
echo $word
exit 0
fi
done
echo "password not found :("
exit 1
Everytime I paste it into the applescript editor and try to compile it i get the following error:
Syntax Error
Expecter end of line, etc. but found parameter name.
The first "for" in the script is highlighted.  Can anyone help me figure out what I need to shange to get the script to run?  I don't know much about applescript. 

Answer 1

I have a password protected dmg from a while back that I have forgotten the password to.  When I made the file, I was still using a formulaic password system where I used the same basic password with a couple substitutions for everything.  Because of this, I have a relatively short (about 5000) list of possible passwords it could be.  Instead of trying all of them by hand, I found a discussion on metafilter with the above script to try all of the passwords against the file automatically.  I have the list in a txt file, but I cannot get the script to work.
