CHOWN & CHMOD - R

CHOWN

chown -R user:mail ./* ./.[!.]*

CHMOD

-#to remove executable permissions

chmod -R 600 /path

-# to make directories transversal

chmod -R u=rwX,g=,o= /path

Above. for the user owner i'm giving capital "X", so it does apply only to directories and not files

-# all files in the current directory, recursively, including hidden files

chmod 755 -R ./* ./.[!.]*

-#all files in the current directory, not recursively, including hidden files

chmod 755 ./* ./.[!.]*

Notes: This will not change an exception filename starting with 2 dots, as example,

./..weirdfilenamehere.txt

Also, be careful not to remove the x bit, or else all your directories will not be accessible (one needs the x bit to cd into a directory).

Remember this: never use bare * but ./* instead.

To avoid problems setting permissions on directories, use find instead.

find . -type f -exec chmodVALUE{} \;

ACL (Access Control Level)

-# To apply the ACL

setfacl -Rm u::rwX,g::0,o::0 /path

-# To make the applied ACL default policy so newly created files will inherit the desired permissions.

setfacl -Rm d:u::rwX,g::0,o::0 /path

Again using capital X so it applies only to directories and not files.
