Questions about operators and filehandles
Well I read, the Programming Perl book by O'reilly and associates, and well I am confused. The two things I have a hard time grasping are:

1. Filehandles
2. Bitwise Operations (bit shifts and such)

BTW, I have always had trouble with bitwise operations in every language...infact I rarely use them so it might even be bytewise operations...all I know is that, if I don't know how to use them it doesn't matter to me. But you can all remedy this right now!!! I need your help now...don't turn your backs when I need you most Unsure.

Well filehandles and bitwise is kind of a broad topic and not something in the scope of this forum, its more of a topic for a perl book otherwise we could be here all week, but if you narrow it down then I'm sure someone can clear up your concerns.

Ok...

What I wanna know is in general, what are filehandles and bitwise operations used for? The rest I can probably figure out on my own time. Or if I have trouble post in this section at a later time. Also what are some examples where you would use bitwise operations over regular operations? Same thing with filehandles, what is the significance of them and how are they used. The technicalities I can read up on. It's just the concepts that confuse me...

Sorry to reply to this three times in a row...but I am dying for help here and not getting any (any help I mean Unsure).

Someone has to know this I have heard all of you jabber about filehandles...so what are they good for and what are bitwise operations good for...I just don't see the significance...

Try manipulating files without using filehandles then you'll see their significance :)

Maybe you shold define manipulating. After all, deletion is a form of manipulation ...

Not in my dictionary...

Manipulate:
Computing: Alter or edit

Yep. You're altering the data by deleting it.

Um altering is totally different from deleting.

Dictionaries aren't vague by nature...if it meant delete it would have said:

alter, edit or delete

Well by erasing a file you're altering the data pattern on your disk.
