Parmenides has asked for the
wisdom of the Perl Monks concerning the following question:
For fun, I am working my way through a perl text book and I have a question about how to make one of the chapter assignments better.
Topic: The chapter that I just read was about filehandles.
My chapter assignment: Write a program that opens a file with STDIN and then writes each line of the file proceded by the file's name and a colon.
My question: Upon reading this chapter assignment, I immediately thought, huh. I don't know how to write the program line by line. After scowring the book for something I might have missed, I finally gave in and took a peek at the answer. The books answer: assume that each line ends with a \n. Since that is just a bit rediculous, how do I parse a file line by line?
