Learn about newline translation on Windows, and how it impacts your code.
- [Voiceover] Some operating systems make a distinction…between text files and binary files.…Windows does this.…Unix based operating systems like Mac OS 10 do not.…For this lesson I will be demonstrating on Windows.…If you're on a Mac or another Unix based OS,…you'll still want to follow along…so you can understand this topic.…Just keep in mind that you will not see this effect…on your system.…So here's a working copy of copyfile.pl from Chapter 12…of the exercise files.…And you notice that we scroll down over here.…
I have file name one, train-station.jpg.…File name two is copy.jpg.…And you notice here train-station.jpg is there…in the directory and copy.jpg is not.…So I'm going to open file one,…which is the train-station.jpg.…I'm going to open that for read…and I'm going to open file two…which is the copy.jpg for write…and it's the overwrite version of write.…The new file version of write.…And then I copy the file.…I'm using the read function from IO file…to read into the buffer.…
There's the buffer.…Up to one megabyte at a time…
Watch to learn the details of the Perl syntax, from variables, conditionals, loops, and data structures to regular expressions, functions, and references. A quick-start guide is included for experienced developers who want to get up and running with Perl 5 fast, and the entire course is recommended for both new and experienced programmers alike.
