Hello martinsmith,

Adding one more solution here without 2 time loops, which may help you here. Let's say following is the Input_file.
Code:
One and a Two
Unix.com is the Best
This as a Line Line
Example duplicate sentence with the word DUPLICATE
UNIX is very good GOOD

Then following is the code.
Code:
awk '{for(i=1;i<=NF;i++){A[tolower($i)]};if(NF == length(A)){print};delete A}'  Input_file

Output will be as follows.
Code:
One and a Two
Unix.com is the Best

EDIT: Above solution should work fine but each time condition will be invoked in for loop so a little change as follows will avoid that also.
Code:
 awk '{for(i=1;i<=NF;i++){A[tolower($i)]}};{if(NF == length(A)){print};delete A}'  Input_file

So above I am closing the loop before and after completion of it I am executing the condition part then.

Thanks,
R. Singh

NAME
fmt - format text SYNOPSIS
width] [file...] DESCRIPTION
The command is a simple text formatter that fills and joins lines to produce output lines of (up to) the number of characters specified in the width option. The default width is 72. concatenates the arguments. If none are given, formats text from the standard input. Blank lines are preserved in the output, as is the spacing between words. does not fill lines beginning with a period for compatibility with Nor does it fill lines starting with Indentation is preserved in the output and input lines with differing indentation are not joined (unless is used). can also be used as an in-line text filter for the command: reformats the text between the cursor location and the end of the paragraph. Options recognizes the following options: Crown margin mode. Preserve the indentation of the first two lines within a paragraph and align the left margin of each subsequent line with that of the second line. This is useful for tagged paragraphs. Split lines only. Do not join short lines to form longer ones. This prevents sample lines of code, and other such "formatted" text, from being unduly combined. Fill output lines to up to width columns. WARNINGS
The width option is acceptable for BSD compatibility, but it may go away in future releases. SEE ALSO
