Basics

A Perl program is an ASCII text file. To run it, you load it into the Perl interpreter. Thus if your program were name "testprog" you would run it via the command perl testprog.

Under Unix, you can can have this happen automatically by making

#!/usr/local/bin/perl

the first line of your program, and changing the attributes the program file to include 'executable'.

Thus, a typical 'hello world' program looks like:

#! /usr/bin/perl

print "hello world \n";

Things to note:

Perl statments all terminate with a ;
You have to explicitly tell print to print the linefeed "\n"
