Your data sample is useless Smilie try to copy/paste again and use [code] tags not [table] tags !

From your spinet
Code:
for filename in *.txt	# you don't need to find anything special and you are in current directory anyway
do
	awk -F"\t" '	# awk have the internal FILENAME variable(read the manual)
				BEGIN {OFS="|"} {print $2,$14,$15,FILENAME}
				' $filename > output.txt
done

Not tested but should work if that's what you want.

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
