Thank you so much sir...for solving my big problem,

Sir I am trying one more thing with same file to display unmatched records

my problem is like this.. for instance say file1 has 1000 records, file 2 has 750 records, file1's 750 records are matching with file 2

I want to display remaining 250 records from file 1

I could able to display matching records, using following script

Code:
awk 'FNR==1{i++}{for(k=1;k<=NF;k++) A[i,FNR,k]=$k}
END{
for(i=1;i<='$d';i++)
{
for(j=1;j<='$c';j++)
if(A[2,i,2]==A[1,j,1] && A[2,i,1]==A[1,j,2])
print A[2,i,2], A[2,i,1], "<==F2 equal F1==>", A[1,j,1],A[1,j,2]
}}' OFS="\t" file1 file2

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
