Nice one Akshay.

I made a modification to allow sorting within the awk statement:

Code:
awk '{A[$1]=A[$1] ? A[$1] OFS $2 : $2}END{for(i in A)print i, A[i] | "sort"}' file*
rs0001 100e-34 1.98e-22 81.98e-22
rs0003 2.8e-01 2.8e-01 42.8e-01
rs0004 3.77e-10
rs008 1.9e-90 1.9e-90

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
