Hello again monks,
I have finished writing a program that requires <STDIN> input to function correctly. Because of this, I want the program to display a small error message when the user provides on file for the program.
For example:
username$: perl myprog.pl /path/path/file
results in the program executing as expected using the data in file. However I want this:
username$: perl myprog.pl
to cause the print out of a message simlar to this:
Error! plese try: 'perl myprog.pl /some/filename'
can this be done easly through an if-else statement? If so how should I check to see if <> is being used or not?
Thank you very much for your time.
