using getopt for both short and long options
Hi ,

I am using getopt for both short and long options as below

SHORTOPTS="a:c"
LONGOPTS="alpha:,charlie"
OPTS=$(getopt -o $SHORTOPTS --longoptions $LONGOPTS -n "$progname" -- "$@")
eval set -- "$OPTS"

while [ $# -gt 0 ]; do
case $1 in
-a|--alpha)
echo "-a or --alpha specified with "$2
shift 2
;;
-c|--charlie)
echo "-c or --charlie specified"
shift
;;
esac
done

if i run the above program like this ./sample1 --al hi or ./sample1 --cha

its taking --al as --alpha and --cha as --charlie

How to avoid this.It should take the option only if i give the entire option as --charlie and not --ch.Please help me.

Regards,
Padmini

template::plugin::html

Template::Plugin::HTML(3)				User Contributed Perl Documentation				 Template::Plugin::HTML(3)

NAME

       Template::Plugin::HTML - Plugin to create HTML elements

SYNOPSIS

	   [% USE HTML %]

	   [% HTML.escape("if (a < b && c > d) ..." %]

	   [% HTML.element(table => { border => 1, cellpadding => 2 }) %]

	   [% HTML.attributes(border => 1, cellpadding => 2) %]

DESCRIPTION

       The "HTML" plugin is a very basic plugin, implementing a few useful methods for generating HTML.

METHODS

   escape(text)
       Returns the source text with any HTML reserved characters such as "<", ">", etc., correctly esacped to their entity equivalents.

   attributes(hash)
       Returns the elements of the hash array passed by reference correctly formatted (e.g. values quoted and correctly escaped) as attributes for
       an HTML element.

   element(type, attributes)
       Generates an HTML element of the specified type and with the attributes provided as an optional hash array reference as the second argument
       or as named arguments.

	   [% HTML.element(table => { border => 1, cellpadding => 2 }) %]
	   [% HTML.element('table', border=1, cellpadding=2) %]
	   [% HTML.element(table => attribs) %]

DEBUGGING

       The HTML plugin accepts a "sorted" option as a constructor argument which, when set to any true value, causes the attributes generated by
       the "attributes()" method (either directly or via "element()") to be returned in sorted order.  Order of attributes isn't important in
       HTML, but this is provided mainly for the purposes of debugging where it is useful to have attributes generated in a deterministic order
       rather than whatever order the hash happened to feel like returning the keys in.

	   [% USE HTML(sorted=1) %]
	   [% HTML.element( foo => { charlie => 1, bravo => 2, alpha => 3 } ) %]

       generates:

	   <foo alpha="3" bravo="2" charlie="1">
