Perfect!

Wow that was quick. Any chance you can explain a little of what you have written. I'm keen to understand rather than just copy and paste code.

Thanks anbu23

In particular I want to make sure that if the folder structure is different:

Code:
//servername.com/version/panasonic3,1_6.7.1
//servername.com/version/panasonic3,2_6.8
//servername.com/version/panasonic2,6_3.0.2
//servername.com/newversion/panasonic3,1_7.1.3

This will still apply the if/else arguments that you have skilfully written.

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
