Re:Merge records based on multiple columns

Hi,

I am not an expert shell scripting programmer ,but I have tried few options

1) For loop by reading each row and doing concatenated grep to find the matching column

2) I have also gone through the link (on this website itself )given below and tried to change given solution as per requirement


shell-programming-and-scripting
208027-merge-multiple-lines-same-file-common-key-using-awk.html

but ordering on the basis of 15th column is still an issue and also I am getting double quotes in concatenation of last field

I am ok with any solution being in KSH,BASH or AWK. Perl and any other language could be the last option but not preferable for now.

I am not sure about OS version too as I am out of my office and can't check

let me know if these informations are helpful

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).

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
