what OS are you under?
Do you have gawk?
here's something to start with: echo 'dominos' | gawk -f gh.awk
where gh.awk is:
Code:
{
  len=length($0)
  for (i=1;i<=len;i++)
    for(j=i+1;j<=len;j++)
      print gensub(".", "_", i, gensub(".", "_", j, $0))
}

locale

LOCALE(1)						    BSD General Commands Manual 						 LOCALE(1)

NAME

     locale -- display locale settings

SYNOPSIS

     locale [-a|m]
     locale [-ck] name [...]

DESCRIPTION

     locale displays information about the current locale, or a list of all available locales.

     When locale is run with no arguments, it will display the current source of each locale category.

     When locale is given the name of a category, it acts as if it had been given each keyword in that category.  For each keyword it is given,
     the current value is displayed.

OPTIONS

     -a       Lists all public locales.

     -c name ...
	      Lists the category name before each keyword, unless it is the same category as the previously displayed keyword.

     -k name ...
	      Displays the name of each keyword prior to its value.

     -m       Lists all available public charmaps.  Darwin locales do not support charmaps, so list all CODESETs instead.

OPERANDS

     The following operand is supported:

     name is the name of a keyword or category to display.  A list of all keywords and categories can be shown with the following command:

     locale -ck LC_ALL

ENVIRONMENT

     LANG	  Used as a substitute for any unset LC_* variable.  If LANG is unset, it will act as if set to "C".  If any of LANG or LC_* are
		  set to invalid values, locale acts as if they are all unset.

     LC_ALL	  Will override the setting of all other LC_* variables.

     LC_COLLATE   Sets the locale for the LC_COLLATE category.

     LC_CTYPE	  Sets the locale for the LC_CTYPE category.

     LC_MESSAGES  Sets the locale for the LC_MESSAGES category.

     LC_MONETARY  Sets the locale for the LC_MONETARY category.

     LC_NUMERIC   Sets the locale for the LC_NUMERIC category.

     LC_TIME	  Sets the locale for the LC_TIME category.

SEE ALSO

     localedef(1), localeconv(3), nl_langinfo(3), setlocale(3)

STANDARDS

     The locale utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     locale appeared in Mac OS X 10.4

Darwin								  August 27, 2004							    Darwin
