The following are the different ways to start Perl.

## Interactive Interpreter

You can enter Perl and start coding right away in the interactive interpreter by starting it from the command line. You can do this from Unix, DOS, or any other system, which provides you a command-line interpreter or shell window.

$perl -e <perl code> # Unix/Linux or C:>perl -e <perl code> # Windows/DOS Here is the list of all the available command-line options − Sr.No.Option & Description 1-d[:debugger] Runs program under a debugger 2-Idirectory Specifies @INC/#include directory 3-T Enables tainting checks 4-t Enables tainting warnings 5-U Allows unsafe operations 6-w Enables many useful warnings 7-W Enables all warnings 8-X Disables all warnings 9-e program Runs Perl script sent in a program 10file Runs Perl script from a given file ## Script from the Command-line A Perl script is a text file, which keeps Perl code in it and it can be executed at the command line by invoking the interpreter on your application, as in the following − $perl script.pl             # Unix/Linux
or
C:>perl script.pl           # Windows/DOS

## Integrated Development Environment

You can run Perl from a graphical user interface (GUI) environment as well. All you need is a GUI application on your system that supports Perl. You can download Padre, The Perl IDE. You can also use Eclipse Plugin EPIC - Perl Editor and IDE for Eclipse if you are familiar with Eclipse.

Before proceeding to the next chapter, make sure your environment is properly set up and working perfectly fine. If you are not able to set up the environment properly then you can take help from your system administrator.

All the examples given in subsequent chapters have been executed with v5.16.2 version available on the CentOS flavor of Linux.
