What does the final "+" mean after the user/group/others rwx permissions
How do you modify or eliminate the "+" symbol?
Example:
(directory)rwxr-x---+
The + indicates that the file has an Access Control List (ACL) with additional permissions.
-
getfacl {dir/file}
to get more info on what is set -
setfacl -b {dir/file}
to remove ACL.
If you did not set this yourself please do not alter it. There probably is a setting there to prevent accidental deletion.
