I'm looking for a Linux command to go through all the directories on my server and find all files with 777 permission. The output would be a list of all those files with full path.

Use find:

find / -type f -perm 0777

And if you like to find all files without Permission 0777 then just enter a ! before the perm, e.g.

find / -type f ! -perm 0777

You can also change the permissions or ownership of all those files resulting from the find execution using the -exec option to avoid change them manually.

Example: In a web server you could need to grant the group to write files:

find /var/www/html -type f -perm 0777 -exec chmod 775 {} \; -exec chgrp www {} \;

    Be very very careful doing this - always worth using -exec ls first in order to see what the effect of your command will do. Find is super powerful and will often find things you didn't expect it to.

  • It's true. My command should be used once you know which files will result from the search.

it's as easy as:

find / -perm 0777

if you only want to match files, use this instead:

find / -type f -perm 0777
