Changing CHMOD permissions in Linux file systems is an important task. Many administrators use the common Octal notation to quickly assign permissions to the User, Group, and Other accounts in a single command.
User (u) | Group (g) | Other (o) | |
---|---|---|---|
Read (r) | 4 | 4 | 4 |
Write (w) | 2 | 2 | 2 |
Execute (x) | 1 | 1 | 1 |
Octal | Permissions |
---|---|
777 | rwxrwxrwx |
755 | rwxr-xr-x |
644 | rw-r–r– |
700 | rwx—— |
750 | rwxr-x— |
