NAME

getopt - Process single-character switches with switch clustering

getopts - Process single-character switches with switch clustering

SYNOPSIS

    use Getopt::Std;
    getopt('oDI');  # -o, -D & -I take arg.  Sets opt_* as a side effect.
    getopts('oif:');  # -o & -i are boolean flags, -f takes an argument
                      # Sets opt_* as a side effect.

DESCRIPTION

The getopt() functions processes single-character switches with switch clustering. Pass one argument which is a string containing all switches that take an argument. For each switch found, sets $opt_x (where x is the switch name) to the value of the argument, or 1 if no argument. Switches which take an argument don't care whether there is a space between the switch and the argument.
