If you still have problems, copy-paste the commands exactly as you ran them and the error messages exactly as you see them. Perhaps that will enable someone with experience dealing with unix tools on windows to help out.

I tried this, but the program just runs and prints nothing and goes back to command prompt. No error messages whatsoever.

I ran this:
awk -f dna.awk f2='2.txt' 1.txt

I use gawk, is there a significant difference between regular awk and gawk?



Aaahh! now its working. Ok I removed the single quotes on '2.txt' and its working. So the code that worked is awk -f dna.awk f2=2.txt 1.txt

I knew there is a simple mistake I have been making.

Thank you very much you all, particularly Alister. You rock.

paste

PASTE(1)						      General Commands Manual							  PASTE(1)

NAME

       paste - paste multiple files together

SYNOPSIS

       paste [-s] [-d list] file...

OPTIONS

       -d     Set delimiter used to separate columns to list.

       -s     Print files sequentially, file k on line k.

EXAMPLES

       paste file1 file2   # Print file1 in col 1, file2 in col 2

       paste -s f1 f2	   # Print f1 on line 1 and f2 on line 2

       paste -d : file1 file2
			   # Print the lines separated by a colon

DESCRIPTION

       Paste  concatenates  corresponding  lines of the given input files and writes them to standard output. The lines of the different files are
       separated by the delimiters given with the option -s. If no list is given, a tab is substituted for every linefeed, except  the	last  one.
       If  end-of-file	is hit on an input file, subsequent lines are empty.  Suppose a set of k files each has one word per line.  Then the paste
       output will have k columns, with the contents of file j in column j.  If the -s flag is given, then the first file is on line 1, the second
       file on line 2, etc.  In effect, -s turns the output sideways.

       If  a list of delimiters is given, they are used in turn.  The C escape sequences 
, 	, \, and  are used for linefeed, tab, backslash,
       and the null string, respectively.
