NAME

true − do nothing, successfully

SYNOPSIS

true
true {−−help,−−version}

DESCRIPTION

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. 

OPTIONS

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.
