getopts

getopts ('

switches

'[, \%

opts

])

Like getopt , except that all valid options are included in switches and options that take an argument are followed by a colon ( : ), e.g.:

getopt('oDI')    # -o, -D, & -I take arguments; there may be other options
getopts('o:DI')  # -o, -D, and -I are the only valid options; only -o
                 # takes an argument
\%opts means the same as with getopt .
