getopt(1)                        User Commands                       getopt(1)



NAME
       getopt - parse command options

SYNOPSIS
       set -- ` getopt optstring $ * `

DESCRIPTION
       The  getopts command supersedes getopt. For more information, see NOTES
       below.


       getopt is used to break up options in command lines for easy parsing by
       shell  procedures and to check for legal options. optstring is a string
       of recognized option letters; see getopt(3C). If a letter  is  followed
       by a colon (:), the option is expected to have an argument which may or
       may not be separated from it by white space. The special  option  -  is
       used  to  delimit  the  end  of  the options. If it is used explicitly,
       getopt recognizes it; otherwise, getopt generates it; in  either  case,
       getopt  places  it at the end of the options. The positional parameters
       ($1 $2 ...) of the shell are reset so that each option is preceded by a
       −  and is in its own positional parameter; each option argument is also
       parsed into its own positional parameter.

EXAMPLES
       Example 1 Processing the arguments for a command



       The following code fragment shows how one might process  the  arguments
       for a command that can take the options -a or -b, as well as the option
       -o, which requires an argument:


         set -- `getopt abo: $*`
         if [ $? != 0 ]
         then
                    echo $USAGE
                    exit 2
         fi
         for i in $*
         do
                    case $i in
                    -a | -b)     FLAG=$i; shift;;
                    -o)           OARG=$2; shift 2;;
                    --)           shift; break;;
                    esac
         done




       This code accepts any of the following as equivalent:


         cmd -aoarg filename1 filename2
         cmd -a -o arg filename1 filename2
         cmd -oarg -a filename1 filename2
         cmd -a -oarg -- filename1 filename2

DIAGNOSTICS
       getopt prints an error message on the standard error when it encounters
       an option letter not included in optstring.

NOTES
       getopt  will  not  be  supported  in  the  next major release. For this
       release a conversion tool has been  provided,  namely,  getoptcvt.  For
       more information, see getopts(1) and getoptcvt(1).


       Reset optind to 1 when rescanning the options.


       getopt  does not support the part of Rule 8 of the command syntax stan‐
       dard (see Intro(1)) that permits groups of  option-arguments  following
       an option to be separated by white space and quoted. For example,

         cmd -a -b -o "xxx z yy" filename



       is  not  handled correctly. To correct this deficiency, use the getopts
       command in place of getopt.


       If an option that takes an option-argument is followed by a value  that
       is the same as one of the options listed in optstring (referring to the
       earlier EXAMPLES section, but using the following command line:

         cmd -o -a filename



       getopt always treats it as an option-argument to -o;  it  never  recog‐
       nizes  -a  as  an  option.  For  this case, the for loop in the example
       shifts past the filename argument.
