Help with Interactive / Non Interactive Shell script

ETC Homework & Coursework Questions

Q. Write a script that behaves both in interactive and non interactive mode. When no arguments are supplied it picks up each C program from the directory and prints first 10 lines.
It then prompts for deletion of the file.
If user supplies arguments with the script , then it works on those files only.

                      • -- - - - - - - - - - - - - - -

The main problem Im facing with this question is how to make the program pick up a C program in case no arguments are specified .

Code :

ls -lrt *.C

Please elaborate it .
