Franklin52 - Thanks for your help. One more question though, If I have another input file

Input file 3
XYZ,Desc1
VZG,Desc2

And if I would like to add more to output file by looking into input file 3, then how would I get the "XYZ" to get the description from input file 3.

Output file
Desc1,Aug 14 10:37 123.XYZ.106.20061023160210.in, EFGH
Desc1,Aug 14 12:59 135.XYZ.107.20061023160210.in, RTYT
Desc1,Aug 14 13:15 234.XYZ.108.20061023160210.in, GHJK

I tried this but no luck

awk -F",| |\\\.\." 'NR==FNR{a[$1]=$2;next}
$4 in a{print $0 "," a[$4]}
' file3 file1

Appreciate your responses.

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
