This section describes command-\/line processing for the {\ttfamily qore} binary; see \mbox{\hyperlink{class_qore_1_1_get_opt}{Qore\+::\+Get\+Opt}} for the class allowing for command-\/line processing in Qore code

Qore will scan the command-\/line for the options in the following table. Arguments after the script name will be passed to the script in the global {\ttfamily ARGV} variable as a list of options. {\ttfamily ARGV\mbox{[}0\mbox{]}} will be the first option and will not be the script name. If no script name is given and the {\ttfamily --exec} option is not used, then Qore code is read from standard input. The {\ttfamily QORE\+\_\+\+ARGV} variable will have the original Qore command-\/line in it, however

Usage\+: {\ttfamily qore \mbox{[}}{\itshape options}{\ttfamily \mbox{]} \mbox{[}}{\itshape script\+\_\+file\+\_\+name}{\ttfamily \mbox{]}}
