true - do nothing, successfully true

true {--help,--version}

This manual page documents the GNU version of true (and probably every other version, as well). true does nothing except return an exit status of 0, meaning ``success''. It can be used as a place holder in shell scripts where a successful command is needed, although the shell built-in command `:' (colon) does the same thing faster. When GNU true is invoked with exactly one argument, the following options are recognized:

"--help" Print a usage message on standard output and exit successfully.

"--version" Print version information on standard output then exit successfully.
