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


`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.
