Perl - Hello World

Writing hello world in perl is almost to simple to justify a post, however there are some caveats and for completeness of this group of posts, it will be included.

Step 1 Install Perl (5.x)

Once installed, make sure that you can access the perl executable.  If perl is not in the path, you will need to add it.

Step 2 Create a Perl Source file

______________________Source File____________________________

#!/opt/perl

print ("Hello World in Perl from ecocrypt.blogspot.com")

______________________End Source____________________________

save the source to a file called helloworld.pl  (or any other name of your choice)

Step 3 Tell Perl to execute the input file

prompt % perl helloworld.pl

Hello World in Perl from ecocrypt.blogspot.com

Congratulate yourself! You have successfully installed perl, create a perl source file, and executed it.
