That looks much better, the data now looks more like this:

Filename1.txt Data1 MoreData1
Filename2.txt Data2 MoreData2
Filename3.txt Data3 MoreData3

However, there's still a problem. I'm assuming that $3 means the 3rd field in that line, unfortunately the data I want to extract has a space between it, so this script just returns the 1st part of it, not the full amount. For example, from above, Data1 can be Da ta1, therefore only Da is returned. The same applies to MoreData1.

I will try to understand your code and put it into my original code.

I'm assuming the code written before the {}s is the same as an IF statement.

Thanks for the reply, I'll have a closer look now to see if I can get things workingSmilie.

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
