Some people aren’t comfortable around a Unix terminal, which can make things difficult if you’re trying to change the read, write, and execute permissions on a file or set of files. The chmod command can, after all, be a little intimidating if you haven’t used it before… not to mention that it can really mess up your system if you don’t use it quite right.
Mac users can find comfort knowing they can easily adjust the read, write, and execute permission on any file(s) or folder using the free BatChmod. This app wraps a GUI around the terminal command so that you only have to select the options you want, and it will do all of the dirty work for you.
The thing I love the most about the app, however, is the Export option. When you use this feature BatChmod will note down the permissions assigned to the object(s), and will create a standalone version of the app that you can use again yourself or share with someone else. When they go to run the exported version of the app they will see the custom message you created when you ran the export as well as a Run button to have the permissions applied to their system:
That feature can be extremely useful if you’ve had to create a complicated set of permissions and don’t want to go through the same hassle later on.
