Setting a file's permissions for two accounts automatically.

Here is my situation. I have two accounts on my mba (work and personal). Most of the time I use the two separately, but now I have to use one folder and its contents between the two accounts, via the 'Shared' folder.

My problem is that the permissions on each file (pdf, pages) are set for the account each was created in. This means that sometimes I must manually adjust the permissions. This is not a major hurdle, but is there someway to automatically give a file permissions for both accounts when I save it into the shared folder?

I was thinking folder actions, but could not see how to do this.

Can anyone suggest a solution?

You need to create a group in the Users and Groups Settings, add each of the users to that group, then set an ACL on the top level, Folder that you are sharing between the two.

chmod -R +a "group:<groupName> allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit" "Path/to/directory/"

You need to change <groupName> to the name of the group you made, and path/to/directory/ to your shared folder path (e.g., /Users/Shared/MyFolder)
