hi ambious,

If you see line JAY (this line was originally in two separate file which i pasted into 1 line and 1 file using paste command). So, JAY has values 2,,3,5 and B+ in both the file. ANN has 5,,5,1 and C in one file and 5,,5,2 and C in 2nd file.

combined_file.txt

Code:

JAY,2,,3,5,B+,JAY,2,,3,5,B+
ANN,5,,5,1,C,ANN,5,,5,2,C

After two lines from two files are pasted in one file (as above), I want to separate line ANN (which has difference) into another file diff_file.txt

diff_file.txt should contain just ANN and not JAY

Code:

ANN,5,,5,1,C,ANN,5,,5,2,C
