first perl program
here is a simple "Hello, World!" program in Perl:
refer to:itfigidea.com#!/usr/bin/perl use strict; use warnings; print "Hello, World!\n";
Here's a breakdown of what's going on in the code:
- The first line (
#!/usr/bin/perl) is called a shebang and tells the operating system to execute this file using the Perl interpreter. - The next two lines (
use strict;anduse warnings;) are called pragmas and enforce stricter rules for variable usage and catch common programming mistakes. - Finally, the
printstatement outputs the string "Hello, World!" to the console followed by a newline character (\n) to start a new line.
Save the above code in a file with a .pl extension, such as hello.pl. Make the file executable using the chmod command:
chmod +x hello.pl
Then, you can run the script by typing the following command in the terminal:
./hello.pl
This should output the message "Hello, World!" to the console.
