Splitting a file based on record sin another file
All,
We receive a file with a large no of records (records can vary) and we have to split it into two files based on another file. e.g. File1: UHDR 2008112 "25187","00000022","00",21-APR-1991,"" ,"D",-000000519,+0000000000,"C", ,+000000000,+000000000,000000000,"2","" ,21-APR-1991 "8Y3H4","0000004H","00",16-APR-1992,"" ,"H",-001621119,+0000000000,"C", ,+000000000,+000000000,000000000,"2","" ,21-APR-1991 "95Y8U","02100971","00",03-MAR-1991,"" ,"H",-000004499,+0000000000,"" , ,+000000000,+000000000,000000000,"2","US",21-APR-1991 "24567","02100973","00",26-SEP-1991,"" ,"H",-000000362,+0000000000,"" , ,+000000000,+000000000,000000000,"2","US",21-APR-1991 -- -- -- UTRL 00144700 File2: 2518720080512 2456720080512 1256720080512 8WE7820080512 8Y3H020080512 8Y3H220080512 8Y3H420080512 8Y3H620080512 - -- -- -- If the first 5 characters of file 2 matched with the chars 2-6 in file1, it should separate those records and put them into another file and rest of the records should be copied into a second file. I tried cut command but as the file1 is quite large, it was taking a lot of time to put the values into a variable and then compare it. Is there a way which can do the above task quite fast. Please help as it is needed urgently. Thanks in anticipation. |
