For more information on indirect filehandles, see the online documentation on the This line is read as "open or die," which sums up how you will usually want your program to handle the situation when a file can't be opened.As described in Hour 3, "Controlling the Program's Flow," if the .Until now, you've opened only files with simple names like that did not include a path.

Programmers might find themselves saying "This time it will work" or "Now I've found all the bugs." This notion of pride in your own work is good to a point; innovation comes from a sense that it is possible to accomplish the impossible. Whenever a program interacts with the outside world, such as opening a filehandle, always make sure the operation has been successful before continuing.

However, this self-confidence can be taken too far and turn into a sense of infallibility, which the ancient Greeks called hubris and that can lead to tragedy—now as then. Perhaps this modern sorcery [programming] especially attracts those who believe in happy endings and fairy godmothers. I've personally debugged a hundred or more programs in which the programmer requested the operating system to do something, didn't check the results, and caused a bug. In your programs, a good error message should indicate what went wrong, why it went wrong, and what you were trying to do.

Spring AOP is one of the key components of Spring Framework.

It is very easy to start with, and can be used for getting complicated things done very easy.

To open a file that's in another directory, you must use a pathname. ] Because our ideas are faulty, we have bugs; hence our optimism is unjustified." Until now, all the snippets and exercises you've seen have dealt with internal data (factoring numbers, sorting data, and so on) or with simple user input.

The pathname describes the path that Perl must take to find the file on your system. When you're dealing with files, your programs talk to an external source over which they have no control.

They act as convenient references (handles, if you will) between your program and the operating system about a particular file.

They contain information about how the file was opened and how far along you are in reading (or writing) the file; they also contain user-definable attributes about how the file is to be read or written.

They have been unable to communicate with the outside world other than to provide messages to the user and receive input from the keyboard. Perl is an outstanding language for reading from and writing to files on disk or elsewhere.
