-The getopt() function processes single-character switches with switch
+The getopts() function 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
+to be recognized.  For each switch found, sets $opt_x (where x is the
 switch name) to the value of the argument if an argument is expected,
 or 1 otherwise.  Switches which take an argument don't care whether
-there is a space between the switch and the argument.

-The getopts() function is similar, but you should pass to it the list of all
-switches to be recognized.  If unspecified switches are found on the
-command-line, the user will be warned that an unknown option was given.
-The getopts() function returns true unless an invalid option was found.
