in reply to is there a way download script source from web?

if you mean the source of the output, then LWP::Simple (see also this recent node: opening a webpage's source).

If you mean the actual (for example) perl source of a url like http://example.com/cgi-bin/foo.pl then no, it's not possible if the example.com's web server is configured properly. (if it were allowed it would be a huge security risk because people would be able to see the internals of your code)

    Seeing code should not be a security risk. Your code should not contain embedded passwords, etc. Also, the Open Source movement has shown that open and available code, combined with a mechanism for others to review and submit changes to that code, results in better security (in general).

    The reason script source isn't available is rather one of these:

    1. The source embodies a trade-secret or some sort of intellectual property.
    2. Script-capable web servers are configured to execute that code, so no mechanism is in place to simply tranfer it -- putting the file up in a downloadable form is an extra step, and most people simply don't bother.
    3. The code is either trivial or publicly available from a different forum (e.g. the Scoop code that drives Kuro5hin has its own site, so Kuro5hin doesn't publish it on the main site).

    The Code that can be seen is not the true Code
