I have a script that I use to move items from one folder to another that works great. Occasionally a file does not have the proper permissions though. How can I add to this applescript to change the file permissions on the file being copied to read/write for all?

This can get very complicated. You usually have to set both the owner and group of a file to an appropriate level. But sometimes it's the permissions on the file and sometimes the permissions on its containing folder. In addition, you have to know in advance the names of a user and group with such privileges to apply the script with administrator privileges!


One common shell command for modifying file permissions can be used as follows:

set ppath to POSIX path of some_alias
do shell script "chown user:group " & quoted form of ppath with administrator privileges


To change the permissions for a folder recursively it's:
do shell script "chown -R user:group " & quoted form of ppath with administrator privileges


Assuming the user 'tom' has administrator privileges, the 'user:group' specification in the above calls would be 'tom:admin'.
