I don't know about other folks or their preferences for languages to program in but here are some of the criteria I use in deciding what language I'm going to write "something" in.

• Compiled, assembled or interpreted?

  If I'm going to write something targeted for an embedded system I'm going to write it in C against a cross compiler or if I need really tight code I'll write in assembler. This is not to take anything away from such targets like Basic Stamps® which you use a "compliator" to convert code written in a BASIC like language into target code.

  So where does Perl fit in? See my next comment.

• Portability and maintainability

  I hate rewriting the same code over and over again. One of the first things I discovered about Perl when I first started writing in it in 1988 was as long as I could port the interpreter to a platform (and at the time I was working on AT&T 3BX machines, HPUX machines, Solaris and SunOS machines all at the same time. If I wrote a system administration script I only wanted to write it once and believe me a Bourne shell or K shell might not be portable due to differences in shell commands between flavors of Unix®.

• No dependencies (or minimal dependencies) on proprietary software

  If I write something I don't want to have to worry about violating a license if I install it somewhere else. This was one of the first things that sent me to use Perl, gcc and a host of other tools at the time. Later when Open Source became a reality I found myself using OS tools more and more in the professional world I live in.

So, in keeping with my life-long philosophy of "Right Tool for the Right Job" I find myself using Perl for the majority of the coding that I do. I do use other languages. For instance my personal website is a collection of JSP pages with an underpinning of Java® servlets and filters. There are also on my hosted site cronjobs written in Perl and BASH. Not to mention stored procedures written in SQL (Postgres actually) in the backend database.

To the bigots and zealots of any stripe: Sorry, there is no one tool that does it all. Close.. but no cigar.

I go through about some perl and advantage. I have some notes. But, i want what is the advantage when compare to other languages.

When compared to which other languages? Different languages have different strengths and weaknesses. The advantages of Perl over Lisp are quite different from the advantages of Perl over C, for instance. However, in general, there are five major reasons that I like Perl, as follows:

1. The CPAN. The hard parts of most programs are already written for you.
2. Perl is a multi-paradigmatic language, thus allowing you to use the best paradigm for solving any given problems. Some problems lend themselves well to an object-oriented solution. Perl supports that (and it's getting a lot better in Perl6). On the other hand, some problems lend themselves more readily to a functional or procedural or hybrid approach, and Perl supports those too.
3. The CPAN. When you need a library, you don't have to hunt all over creation and back, because you always know right where to find it.
4. The documentation. The Camel book is easily the second-best computer-related book I have ever encountered. (The best is the Inform Designer's Manual, which probably ought to be studied in literature classes.)
5. The CPAN. It does your work for you.

What is the security we are providing when compare to other languages (particulary in web).

If you are concerned about security, you should definitely look into taint checking.

Nowadays, microsoft(vb.net) and sunbeam products(java products) is some high pitch than perl. so, what is the reason why they prefer those softwares. so what are the drawbacks in our software. How we going to solve them the bugs in possible ways.

I'm not clear exactly what you're asking here. Are you asking why we prefer Perl over VB and/or Java? Those are two very different questions. Java actually is good for some things; notably, for GUI stuff, it has some things Perl so far lacks. However, in general, Java just feels wrong to me in ways that Perl feels right, particularly in terms of binding and paradigmatic issues. As far as VB, my opinion on that has always been that VB is more of a (quite good) macro toolkit for Windows -- it works very well for that, but as a programming language it leaves a lot to be desired. Things Perl has that VB doesn't include, among other things, very good text-handling capabilities, general paradigmatic flexibility, sensible variable scoping and binding semantics, and the CPAN. Did I mention the CPAN already?

what are all the things very useful and easy in perl to done when compare to other language. (For eg. we can do these thing in perl it's easy and fast when doing that software is very vast like that).

This is really not very different from your first question, and again, I have to say that Perl's advantages really depend on what language you're comparing it to. Unlike lesser languages like VB (which is basically a one-trick pony: unless your main goal is to whip together a dialog box real quick, it has no other strengths), Perl has *lots* of strengths; any given one of them may be something that a lot of languages have, but when you compare it to any given other language, you see the things that Perl has that the other language doesn't. So to answer these sorts of questions properly, you really need to specify *which* other language you want to compare Perl to. *Most* tasks are very easy to do in Perl compared to many other languages. The only notable exception I'm aware of is GUI development (unless you count a CGI front-end as a GUI, in which case Perl is great for that).

Nowadays, microsoft(vb.net) and sunbeam products(java products) is some high pitch than perl. so, what is the reason why they prefer those softwares. so what are the drawbacks in our software. How we going to solve them the bugs in possible ways.

I would say that one of the big things is that .NET comes on most new computers. A Java Runtime Environment comes on most computers. Perl doesn't come on most (Windows) computers by default. And that's one of the big problems.

I don't really know how to solve that though.

If we giving awareness in perl what are the points we can mention.
(and all of your questions about advantages)

Why do you like using Perl? There are the advantages. Me, personally, I don't feel like I need to be concentrating on syntax all of the time. Also, I don't feel like I have to worry about all of the details all of the time. That means to me that I can get right to the heart of the problem without worrying about everything else... which makes me work faster.

It was a learning curve, but once I got it, I can do something in Perl a lot faster than in any other language! That doesn't mean the programs run faster; that means I'm done faster. For the amount of computation I tend to do, that a program run time of 30s vs. 20s doesn't matter if it took me an hour to program in Perl vs. three hours in a different language.

Agreed there. I'm currently embarking on a Python project. Just another "right tool for the job" project. I've used python before, it's not a bad language, I just don't feel comfortable with all the rules. When I write code in perl I don't think about those rules, I just write the code. I prefer perl over almost any language I've used in the past, doesn't mean I get to use it all the time though. When another language makes more sense for the job, I switch gears. I figure I can always look forward to my next perl project. :)

I also use Perl because 90% of every Perl application has already been written, tested, and just plain-old works. No other language now or in the past has ever had that.

Perl is not the best tool for all jobs. It just happens to be an excellent tool for the jobs I tend to work on.

Perl is More useful

• when one can want to do the task in simplest, easier and fastest way to complete the task.
• Do the same or repeated task in text manipulations in large files.
• Data conversion or text processing jobs IN e-publishing.
• One who wants to learn the language quickly he can choose PERL due to its simplicity in syntax and operation is in greater.
• Due to presence of large availability modules from CPAN.
• One who wants to do the new things, most probably it was done by others in CPAN, so it gives some idea to new comers.
