Answer / Ramesh Bhagat
To get the first and last records from a flat file with 1000 records, you can use the head and tail commands in Unix or Linux. The head command shows the first n lines of a file (by default, it shows the first 10 lines), while the tail command shows the last n lines (by default, it shows the last 10 lines). To get only the first record, you can use head -n 1, and to get only the last record, you can use tail -n +999 (assuming that records are numbered starting from 1).
