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))
}

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
