如何将多个Perl单行合并到一个脚本中？

perl -e 'print "Hello, World!\n"; print "This is a Perl script with multiple lines merged.\n";'

Hello, World!
This is a Perl script with multiple lines merged.

#!/usr/bin/perl

$message1 = "Hello, World!\n";
$message2 = "This is a Perl script with multiple lines merged.\n";

print $message1;
print $message2;

perl -x merged_script.pl
