Hi R. Singh

I tried yor script with awk 'BEGIN{for(i=1;i<=ARGC;i++){O=O?O OFS ARGV[i]:ARGV[i]};print O} FNR==NR{A[$1]=$0;next} ($1 in A){print A[$1] OFS $NF}' *filename*

actually the header of all fiels are present, but only columns of two files are reported ( Ihave more than 1000 files..):

Code:
file1   file2   file3   file4   
1/2-SBSRNA4	187 102
A1BG	114 203
A1BG-AS1	552 772

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
