A numeric mode is from one to four octal digitsderived by adding up the bits with values 4, 2, and 1. This may be true if different users uploaded the WordPress package and the Plugin or Theme.

We'll save that for the Linux system administration course. Changing permission behavior with setuid, setgid, and sticky bits[ edit ] Unix-like systems typically employ three additional modes.

When setgid is applied to a directory, new files and directories created under that directory will inherit their group from that directory. Technical Description chmod changes the file mode of each specified FILE according to MODE, which can be either a symbolic representation of changes to make, or an octal number representing the bit pattern for the new mode bits.

These permissions control the ability of the users to view, change, navigate, and execute the contents of the file system. In Unix-like operating systems, chmod is the command and system call which may change the access permissions to file system objects (files and directories).

It may also alter special mode flags. The request is filtered by the umask.
