What Is chmod?
The purpose of chmod – which stands for Change Mode – is to change access permissions for files and directories. It’s also able to modify special mode flags, such as sticky bit mode, SUID, and SGID. It’s been present in Linux and other Unix-like operating systems since the 70s, in AT&T’s Unix Version One, but in the time it’s been in use, a number of access_control_lists have been added to increase the flexibility of the command.
