4.2.10 RequireArgs
The
requireArgs
command is an advanced feature intended for use with script files. This
command lets you specify the required number of arguments for subsequent commands.
If a CLI script has this command and the number of arguments provided does not provide at
least the number of required arguments specified with
RequireArgs
, the script is
terminated.
Syntax
requireArgs <integer> [optionalDisplayStringOnError]
where
<integer>
is the required number of arguments for subsequent commands and
[optionalDisplayStringOnError]
is a string that is displayed to the user if the
argument count is not satisfied.
Examples
requireArgs 8
Checks that at least 8 arguments are present for the current script, and terminates the
script if not.
