To delete files you no longer require, use the rm command. The rm command eliminates entries for a particular file, group of files, or picky set of files from a directory list. When you use the rm command, user confirmation, read permission, and write permission are not necessary before a file is deleted. Use the REMOVE command to get rid of any rows that you created that are not supposed to be in the table.

Example Output File Rows: R001 11, 12 R002 F16,F17, F18, F19 • The command for executing the program should accept the complete path to the input file as an argument and should return the full path to the output file.

To fulfill this challenge, you can start by creating a 2D array to represent the seating arrangement of the movie theater. Then, for each reservation request, you can iterate through the array and check for available seats that meet the buffer requirements.
When you find an available block of seats, you can assign them to the reservation and update the array to reflect the new seating assignment. In the output file, you can write the reservation number and the assigned seats in the format specified in the prompt. It is important to consider edge cases such as when a reservation request cannot be fulfilled due to lack of available seats, and how to handle overbooking scenarios.
