There is also a Perl core module named CPAN; it is usually differentiated from the repository itself by using the name CPAN.pm. CPAN.pm is mainly an interactive shell which can be used to search for, download, and install distributions. An interactive shell called cpan is also provided in the Perl core, and is the usual way of running CPAN.pm ...
Perl Package Manager (PPM) is a Perl utility intended to simplify the tasks of locating, installing, upgrading and removing software packages. It can determine if the most recent version of a software package is installed on a system, and can install or upgrade that package from a local or remote host.
However, Strawberry Perl incorporates the MinGW development environment during installation. All the installed Perl tools are set up to use these built-in libraries and development tools to compile XS modules as required. This allows Strawberry Perl to use many XS modules without modification, directly from the CPAN.
Perl borrows features from other programming languages including C, sh, AWK, and sed. [1] It provides text processing facilities without the arbitrary data-length limits of many contemporary Unix command line tools. [16] Perl is a highly expressive programming language: source code for a given algorithm can be short and highly compressible. [17 ...
Repositories may be solely for particular programs, such as CPAN for the Perl programming language, or for an entire operating system. Operators of such repositories typically provide a package management system , tools intended to search for, install and otherwise manipulate software packages from the repositories.
ActivePerl is a distribution of Perl from ActiveState (formerly part of Sophos) for Windows, macOS, Linux, Solaris, AIX and HP-UX.. A few main editions are available, including: Community (free, for development use only), and several paid tiers up to Enterprise that includes support for OEM licensing.
Apart from creating, manipulating, loading, and installing binary PAR archives, the PAR module can be used to create standalone executables from complex applications using its PAR::Packer extension. Like many other Perl modules, PAR is primarily distributed via the CPAN where numerous extensions have been published. These include:
#!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.
