false

Do nothing, returning a non-zero (false) exit status.

Syntax
      false

`false' does nothing except return an exit status of 1, meaning "failure". It can be used as a place holder in shell scripts where an unsuccessful command is needed.

`false' ignores all command line arguments, even --help and --version, since to do otherwise would change expected behavior that some programmers may be relying on.

This version of `false' is implemented as a C program, and is thus more secure and faster than a shell script implementation, and may safely be used as a dummy shell for the purpose of disabling accounts.

"False in one thing, false in everything" ~ Legal maxim
