The Perl community has a sizable library of distributions available for search and download via CPAN. Perl is a language allowing many different styles of programming. A developer is as likely to find a module written in a procedural style (for example, Test::Simple ) as object-oriented (e.g. XML::Parser ), both are considered equally valid ...
#!/usr/bin/perl print "Hello, World!\n"; The hash mark character introduces a comment in Perl, which runs up to the end of the line of code and is ignored by the compiler (except on Windows). The comment used here is of a special kind: it’s called the shebang line.
Parse::MediaWikiDump is a Perl module created by Triddle that makes accessing the information in a MediaWiki dump file easy. Its successor MediaWiki::DumpFile is written by the same author and also available on the CPAN .
The Perl virtual machine is a stack-based process virtual machine implemented as an opcodes interpreter which runs previously compiled programs written in the Perl language. The opcodes interpreter is a part of the Perl interpreter, which also contains a compiler (lexer, parser and optimizer) in one executable file, commonly /usr/bin/perl on various Unix-like systems or perl.exe on Microsoft ...
/bin: Stands for binaries and contains certain fundamental utilities, such as ls or cp, that are needed to mount /usr, when that is a separate filesystem, or to run in one-user (administrative) mode when /usr cannot be mounted. In System V.4, this is a symlink to /usr/bin. Otherwise, it needs to be on the root filesystem itself. /boot
Use of the linkify plugin plus a wikilink config file allows you to see all those [[links]] that everyone is typing as real links. Wingaim users who haven't installed activeperl, download activeperl 5.8 first, as per Perl plugin support, then reinstall gaim. Download the Linkify Perl script from sourceforge.
#!usr/bin/perl – called the "shebang line", after the hash symbol (#) and ! (bang) at the beginning of the line. It is also known as the interpreter directive. # – the number sign, also called the hash symbol. In Perl, the # indicates the start of a comment. It instructs perl to ignore the rest of the line and not execute it as script code.
The first line is a shebang, which identifies the file as a Perl script that can be executed directly on the command line on Unix/Linux systems. The other two are pragmas turning on warnings and strict mode, which are mandated by fashionable Perl programming style. This next example is a C/C++ programming language boilerplate, #include guard.
