how to display the unique strings in two files using shell script or commands.
I tried diff and cmp but it shows the entire line, i need only the mismatched strings.
awk -F, 'NR==FNR{for(i=1;i<=NF;i++){A[i,FNR]=$i};next}{for(i=1;i<=NF;i++){if(A[i,FNR]!=$i){print A[i,FNR],"(line "FNR","i" Column) in file1 does not match with file2";}}}' file1 file2
bash-3.00$ awk -F, 'NR==FNR{for(i=1;i<=NF;i++){A[i,FNR]=$i};next}{for(i=1;i<=NF;i++){if(A[i,FNR]!=$i){print A[i,FNR],"(line "FNR","i" Column) in file1 does not match with file2";}}}' file1.txt file2.txt
