How to chmod files that have a specific set of permissions

chmod: permissions of a directory don't changeHaving trouble with chmodSite creation script - missing chmod permissionsBest practices for permissions in major directories in UbuntuPermission denied for 'sudo' after 'sudo chmod 666 /usr'Setting permissions for /var/www/mysite?chmod hard drive at grub?I set permission with chmod, but files created later don't have the same permissionsFix permissions of server after accidental chmodchmod does not seem to be changing permissions of a sd card

I want to find all files in a folder that have -rw-r----- (640? is that the right code?) permissions, and change them all to have -rw-rw-rw- instead. How do I do this, with chmod?

I know I could do the whole folder with

sudo chmod -R 666 /path/to/folder

but I think (perhaps mistakenly?) that it would be more efficient to just do the ones that actually need it?

Alternatively, rather than specifically looking for -rw-r-----, I could chmod any file that doesn't have 666 already? Would that be better?

  You definitely do not want to do chmod -R 666, since it would remove the executable bit from the folder, making it unbrowseable. chmod -R a=rwX maybe.

  Yes that just occurred to me - I think chmod -R +r,+w might be best. There shouldn't be any executable stuff in that folder anyway.

  If there's nothing executable, including no subfolders, no need for -R, just do chmod 666 /path/*.

  To find only files (not oddly-specified directories) with permissions 640, add -type f eg: find -type f /path/to/folder -perm 640 -exec chmod 666 {} ;

  And don't forget about using + instead of ; with -exec so it only runs chmod once, instead of separately for each file.
