Determining if a Mac OS X directory is locked

[Ken Ray]

Tom,

You can use shell() to do an "ls -l" on the parent of the directory
you're looking for. Look at the first "column" of data (the access
modes) to determine if the directory is read only or not. 

Here's a way to do it (in this example, I'm looking at a directory
called "Evaluate" on my desktop to see if it is read only):

on mouseUp
  answer IsReadOnly("Evaluate")
end mouseUp

function IsReadOnly pWhat 
  -- Go to the home folder, then the Desktop 
  -- folder inside, then get a listing
  put shell("cd ~;cd desktop;ls -l") into temp
  put lineOffset(space & pWhat &cr,temp) into tLine
  put char 2 to 10 of word 1 of tLine into tAccessModes
  return ("w" is in tAccessModes)
end IsReadOnly

Hope this helps,

Ken Ray
