What is the numeric and alphabetical method for granting permissions?

Answer»

GRANTING permission on FILES and directories is one of the crucial and data security stuff for Linux System Administrator. Permission on any file or directory is a combination of 9 alphabets. FIRST 3 from the left represents owner access, then middle 3 represents user group access and the last 3 are for other users who are not the owner or part of a group having access.

rwxrwxr

We have several ways to grant permissions using the numeric and alphabetical method. Having knowledge of these shortcuts makes administrators life easy.

rwx = 111 in binary = 7

rw- = 110 in binary = 6

r-x = 101 in binary = 5

r-- = 100 in binary = 4

So when you mention 765 numeric CODE to provide access permission, User will get like:- rwxrw-r-x
