            Bug ID: 215207
           Summary: [patch] getopt(1) example mangles command-line
                    arguments with embedded spaces
           Product: Base System
           Version: CURRENT

Proposed fix

The provided getopt(1) example in the manual page mangles command-line
arguments containing spaces by splitting them through IFS.

Consider the following minimal example script, written by following the man
page example.

#!/bin/sh
args=3D`getopt a: $*`
if [ $? -ne 0 ]; then
   echo 'Error'
   exit 2
fi

set -- $args
while :; do
   case "$1" in
   -a)
           flags=3D-a
           shift
           ;;
   --)
           shift; break
           ;;
   esac
done

for i; do
    echo "Arg $i"
    shift
done

When the above script is run with 'a b' as an argument, it will output
Arg a
Arg b
rather than
Arg a b

The problem can be fixed by applying the attached patch.  Note that the pat=
ch
does not address option arguments with embedded spaces.
