Agustin:
1. What *exactly* do you mean "both" ways?
2. References...
From the Getopt::Std man page:
getopt('oDI'); # -o, -D & -I take arg. Sets opt_*...
getopts('oif:'); # -o & -i are boolean flags, -f takes an argument
# Sets opt_*...
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.
From "The Ram Book":
Getop::Std also provides the getopts function which lets you specify
whether each option is Boolean or takes a value. Arguments that take a
value... are indicated by a ':'
In summary:
getopts() will set BOOLEAN values OR the value supplied *if* the option
is followed by a ':' in the function call getopts("x:").
getopt() will set the command-line value.
