Finding and removing files with weak permissions

This is a nice little script that I use to clean up files and directories with poor permissions. Its great to use in preparation before installing mod_suPHP/PHP suexec.

#!/bin/bash

# Make sure all files are owned by the correct user. Get rid of file owned by nobody
for i in $(ls /home| cut -f1 -d/); do chown -R $i:$i /home/$i/public_html/*; done

# Find all files that are 777 and change them to 644
for i in $(find /home/*/public_html -perm 777 -type f); do chmod 644 $i; done

# Find all directories that are 777 and change them to 755
for i in $(find /home/*/public_html -perm 777 -type d); do chmod 755 $i; done

    Hey,

    I’m having this problem with one of my accounts, bassically it’s an image upload website, and someone uploaded porn and I tried to delete it, but I couldn’t, it said I didn’t have permission to! — so I just renamed it for time being, but these files (images) don’t seem to have writable names ;; which is why I think I cannot delete them!

    You will probably want to verify the permissions and ownerships of the file. Also, be mindful of what user you are logged in as. If you’re still having trouble, I would suggest submitting a support ticket.
