Hi experts, I need to compare two files and get the difference between the two files. F1 is the base file.I need to print out all the lines missing in F2, and the extra lines in F2 and also the mismatched lines between F1 and F2. If they are mismatching then i need to print out the exact line number and column numbers where they are mismatching. I need to do this using unix and awk.Please help. for example: file F1 ====== "account";"slash";"tran_no";"account_name";"rowstamp" "DEUTSCHE BANK ";"/";" 22";" ";0000000000BAC757 "DEUTSCHE BANK ";"/";" 23";" ";0000000000BAC758 "DEUTSCHE BANK ";"/";" 25";" ";0000000000BAC759 "DEUTSCHE BANK ";"/";" 26";"ARVAL Fuel Card ";0000000000BADD1C "DEUTSCHE BANK ";"/";" 27";"ARVAL FUEL CARD ";0000000000BADD45 "DEUTSCHE BANK ";"/";" 28";"Petty Cash ";0000000000BADD62 "DEUTSCHE BANK ";"/";" 29";"COLEG LLYSFASI ";0000000000BADD8D "DEUTSCHE BANK ";"/";" 30";"G.Rowlands ";0000000000BADD90 "DEUTSCHE BANK ";"/";" 31";"DEESIDE COLLEGE ";0000000000BADDB5 "DEUTSCHE BANK ";"/";" 33";"C DAVIES EXPENSES ";0000000000BADE51 "DEUTSCHE BANK ";"/";" 34";"CAPITA ";0000000000BADE54 "DEUTSCHE BANK ";"/";" 35";"LOMBARD ";0000000000BADE81 "DEUTSCHE BANK ";"/";" 36";"ARVAL FUEL ";0000000000BADEAC "DEUTSCHE BANK ";"/";" 37";" ";0000000000BADF76 "DEUTSCHE BANK ";"/";" 38";" ";0000000000BADF79 file F2 ======= "account";"slash";"tran_no";"account_name";"rowstamp" "DEUTSCHE BANK ";"/";" 21";" ";0000000000BB011A "DEUTSCHE BANK ";"/";" 23";"ARVAL FUEL ";0000000000BB011B "DEUTSCHE BANK ";"/";" 24";"AAT - E FERRARA ";0000000000BB011C "DEUTSCHE BANK ";"/";" 28";"LOMBARD VEHICLE MANAGEMENT ";0000000000BB0379 "DEUTSCHE BANK ";"/";" 29";" ";0000000000BB03BF "DEUTSCHE BANK ";"/";" 30";" ";0000000000BB03C2 "DEUTSCHE BANK ";"/";" 31";" ";0000000000BB03C5 "DEUTSCHE BANK ";"/";" 32";" ";0000000000BB03C8 "DEUTSCHE BANK ";"/";" 33";" ";0000000000BB03EE "DEUTSCHE BANK ";"/";" 34";"E FERRARA EXPENSES ";0000000000BB047A "DEUTSCHE BANK ";"/";" 35";"R DAVIES ";0000000000BB04A9 "DEUTSCHE BANK ";"/";" 36";"LEASE 360 EVOLUTION ";0000000000BB04D7 "DEUTSCHE BANK ";"/";" 39";" ";0000000000BB05D0 "DEUTSCHE BANK ";"/";" 40";" ";0000000000BB05D3 "DEUTSCHE BANK ";"/";" 41";" ";0000000000BB05D6 "DEUTSCHE BANK ";"/";" 42";" ";0000000000BB05D9 "DEUTSCHE BANK ";"/";" 43";" ";0000000000BB05DC "DEUTSCHE BANK ";"/";" 44";" ";0000000000BB05DF Thanks in advance
