I got tired of getting permissions errors on Apache/Zend/PHP so I did:
chmod -R 777 my_website_root
I know… a bit silly… Now Apache will serve up practically everything, even breakfast 
How do I go back, 777 is the only modifier I know…
/jlar
And it’s a mode that should very seldom be used. Much more useful to learn these two commonly used modes: 644 and 755.
All numbers to you? Try these equivalent descriptors u=rw,g=r,o=r and u=rwx,g=rx,o=rx.
Still just a bunch of letters to you? Then try this tutorial: File system permissions - Wikipedia, the free encyclopedia
Oh and how to get back your original modes. Well if you didn’t have a backup, then you have to guess what the original modes were. Something to think about next time you are tempted to do a chmod -R.

For the number side of Chmod, it’s based on there numbers…
- 4 = Read
- 2 = Write
- 1 = Execute
If you notice, you can’t add any of these numbers up to equal another set. IE: If I want to add the permissions to execute and write for root, I would add 1 + 2 = 3, so I would issue the command: chmod 300 file.txt. You can also use the alphabetical method for permissions: you can add just one permission at a time, rather than editing the entire set as in the case of the number method. For this, you need to declare which type of user will gain or lose a specified permission. In short, you have to the issue a command like the following:
chmod u+w file.txt
The above command will allow the group: User to write this file. The different groups include…
- u = User
- g = Group
- o = Others
- a = All User
Then you can also change the plus sign (+) to a minus sign (-) to remove a permission. The following…
chmod u-w file.txt
That would remove “User” permission to write the file.
In your case, I would go with the numbers method, so you can edit all the permissions all at once rather than changing them one-by-one.
Hope that helps.
Thanks everyone…
