A chmod command first appeared in AT&T Unix version 1, along with the chmod system call. As systems grew in number and types of users, access-control lists [3] were added to many file systems in addition to these most basic modes to increase flexibility.

In some cases, menu options or functions may be made visible or hidden depending on a user's permission level; this kind of user interface is referred to as permission-driven.

The setuid and setgid bits are normally represented as the values 4 for setuid and 2 for setgid in the high-order octal digit of the file mode.
