Perl: nothing happens when I run "perl" from the command line

If I run on my perlown from the linux command line, nothing happens. I see that the cursor moves along the line, and if I enter print "Hello, world";, nothing happens anyway. Is there anything I can enter from the command line? I know that you can run perl -e 'print "Hello, world"';and how to create a perl script. Just wondering why the launch perlitself does nothing.

Enter the following:

$ perl
print "Hello World\n";
Ctrl-D
Hello World
$

In the last line, you hold down the control key and press D. Without typing Ctrl-D.

stty -a, , Ctrl-D - EOF. Perl STDIN. , ?

(Windows, cmd shell), perl, STDIN, Ctrl-Z, . :

C:\perl>perl
$a = "asd";
print "\$a = '$a'";
^Z
$a = 'asd'
C:\perl>perl
use Data::Dumper;
print Dumper [ 3.14 ];
^Z
$VAR1 = [
          '3.14'
        ];
