This is UNIX question asked in DataStage Interview. Say I have n numbers of records in a text file. I want first 3 records in 1st file, last three records in 3rd file and remaining n-6 records in 2nd file. (Note: we don't know how many records are there in the File. I am getting one file on daily basis and I want three target files as asked above)
