Implements default import method for modules
The Exporter module implements an import method which allows a module to export functions and variables to its users' name spaces. Many modules use Exporter rather than implementing their own import method because Exporter provides a highly flexible interface, with an implementation optimized for the common case.

This package is the shared library for perl.
JSON::PP is a pure perl JSON decoder/encoder, and (almost) compatible to much faster JSON::XS written by Marc Lehmann in C. JSON::PP works as a fallback module when you use JSON module without having installed JSON::XS. Because of this fallback feature of JSON.pm, JSON::PP tries not to be more JavaScript-friendly than JSON::XS (i.e. not to escape extra characters such as U+2028 and U+2029, etc), in order for you not to lose such JavaScript-friendliness silently when you use JSON.pm and install JSON::XS for speed or by accident. If you need JavaScript-friendly RFC7159-compliant pure perl module, try JSON::Tiny, which is derived from Mojolicious web framework and is also smaller and faster than JSON::PP.
Common Scalar and List utility subroutines
This package contains a selection of subroutines that people have expressed would be nice to have in the perl core, but the usage would not really be high enough to warrant the use of a keyword, and the size so small such that being individual extensions would be wasteful.
The Carp routines are useful in your own modules because they act like die() or warn(), but with a message which is more likely to be useful to a user of your module. In the case of cluck, confess, and longmess that context is a summary of every call in the call-stack. For a shorter message you can use carp or croak which report the error as being from where your module was called. There is no guarantee that that is where the error was, but it is a good educated guess.
Extended processing of command line options
Module Getopt::Long implements an extended getopt function called GetOptions(). This function implements the POSIX standard for command line options, with GNU extensions, while still capable of handling the traditional one-letter options.
The Encode module provides the interface between Perl strings and the rest of the system. Perl strings are sequences of characters.
A set of basic GNU tools commonly used in shell scripts
These are the GNU core utilities. This package is the combination of the old GNU fileutils, sh-utils, and textutils packages.
This pragma allows you to declare constants at compile-time. When a constant is used in an expression, Perl replaces it with its value at compile time, and may then optimize the expression further. In particular, any code in an "if (CONSTANT)" block will be optimized away if the constant is false.
Stringified perl data structures, suitable for both printing and eval
Given a list of scalars or reference variables, writes out their contents in perl syntax. The references can also be objects. The content of each variable is output in a single Perl statement. Handles self-referential structures correctly. The return value can be evaled to get back an identical copy of the original reference structure. (Please do consider the security implications of eval'ing code from untrusted sources!)
A highly capable, feature-rich programming language
Perl 5 is a highly capable, feature-rich programming language with over 30 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large scale development projects.
Arbitrary size integer/float math package
Math::BigInt provides support for arbitrary precision integers. Overloading is also provided for Perl operators.
Bash is the GNU Project's shell. Bash is the Bourne Again SHell. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers functional improvements over sh for both programming and interactive use. In addition, most sh scripts can be run by Bash without modification.
