As you continue to read you will learn some of the basics and some great places to turn to learn the language itself.

It is impossible to go into all of the intricacies of the language in this short article. One thing to remember is that Perl is a complex programming language that entire books were written about. Upon pressing return your script will execute and you'll see the 'hello.' message printed on the screen! Now all that's left to do is write a script that actually does something. Looks just like what we typed on the command line earlier! To run this script using Terminal you first open Terminal, use the cd command to point to the directory which contains the script and then type perl. The next line gives Perl the command to print to the Terminal. Normally whenever you see this symbol, anything to the right of it is a comment. The # symbol is actually a comment designator.

The line may be slightly different depending on your operating system but this is what you will usually see with Mac OS X. This is how all Perl scripts must start - with the path to Perl. Note that that the very first line of the script points to Perl.

Remember, with Mac OS X you are really running the UNIX operating system underneath a Macintosh user experience! Assume we have the following text stored in a file named : #!/usr/bin/perl pl and should be saved with UNIX linefeeds, otherwise Perl will get confused and return confusing errors when it attempts to run your scripts. Most of the time you will write your Perl scripts and store them in a text file. Perl performed the task flawlessly, as it told us Hello! We then called Perl passing the -e command which tells Perl that we are including actual Perl code between the single quotes and expect it to be interpreted, executed and the results displayed in the Terminal.

In this example we are using Perl 5.6.0 specifically built for Mac OS X. This tells Perl to spit back its version information. Don't let this scare you though, as you'll soon learn, the Terminal isn't so scary.Р”Р„s you can see in Figure 1, we ran Perl from within the Terminal passing the -v command. Because Perl is based in the command line, you primarily run Perl scripts using the Terminal application that comes with Mac OS X. I use BBEdit from Bare Bones Software since it automatically colors the syntax of your Perl script and is simply the best programmer's text editor available for Mac OS X. You can create a Perl script with any text editor. Perl (verion 5.6 as of this writing) comes pre-installed with Mac OS X so there really isn't anything to install or configure. As long as you don't need a fancy GUI, Perl may just have an answer for you.

It can just as easily massage massive amounts of data on your local computer as it can connect to a remote server, across an ocean, and feed it in streams. It is an expert at manipulating text, strings, numbers, streams of data, files and directories. It's strength lies in the fact that it can perform extremely complex tasks easily while not being too big or bulky for the simpler tasks. Perl is an advanced, cross-platform programming language created by Larry Wall. Perl is short for 'Practical Extraction and Report Language.' However, Perl really doesn't sound too interesting when you put it in those terms, so, now that you know that much, forget everything that you've learned up to this point.
