CLI - Command to change all 777 privileges to 755

[Oceanwatcher]

I am looking for a command that can change all instances of files and folders with 777 to 755.

I have a server with several things installed and have had to use 777 on a number of files and folders. But after installing suexec and suphp, this is now unnecessary, even unwanted, so I have to change all to 755.

This does not mean I want to change all files and folders to 755. Only those that has 777 privileges... It has to change on subfolders as well as far down as they go.

Any good suggestions for command to run?

find /path/to/search -perm 777 -print

Feel free to consult the manual:

man find

Once you're sure that the list of files that you got back from above command is what you really really really want to change (e.g. no essential system files got listed !!) you can trigger a slight variation of the above command to do all those changes automatically for you.

find /path/to/search -perm 777 -print -exec chmod 755 {} \;

Fantastic! I knew there was someone out there that knew this!

*Off to fix all*

Thank you very much!!

I just found a typo in my posting. I corrected it now.

If you only wanted to change folders to 755 and change files to 644 then you could run the following:

chmod -R u=rwX, g=rX, o=rX

The uppercase X character tells it to only set the execute permission on folders and not files. It won't work for you if you have some binary files in one of the (sub)folders that need 755 for executing as they will all get converted to 644 permissions.

Is there a similar command to find files and folders with anything but the logged in user/owner?

I also sometimes have problems with folders and files with the wrong owner.
