This program is part of the Comparative Programming :: Echo set of examples.
This example could be a one liner in Perl, but we’ve stretched it to three lines to make sure it’s well formed. Besides a directive at the top of the file pointing to the Perl interpreter, and a single module ‘use’ statement, the body of our program is a single line joining all of our input arguments (provided automatically in @ARGV) with a space as the delimeter.
print join(’ ‘, @ARGV) . "\n";
Program Source: echo.pl
Running the example
From the command line:
perl echo.pl Hello World
