From <a href="http://faq.perl.org/perlfaq8.html" rel="nofollow noreferrer">perlfaq8</a>'s answer to <a href="http://faq.perl.org/perlfaq8.html#How_do_I_clear_the_s" rel="nofollow noreferrer">How do I clear the screen</a>:

<hr>

To clear the screen, you just have to print the special sequence that tells the terminal to clear the screen. Once you have that sequence, output it when you want to clear the screen.

You can use the Term::ANSIScreen module to get the special sequence. Import the cls function (or the :screen tag):

<pre><code>use Term::ANSIScreen qw(cls);
my $clear_screen = cls();

print $clear_screen;
</code></pre>

The Term::Cap module can also get the special sequence if you want to deal with the low-level details of terminal control. The Tputs method returns the string for the given capability:

<pre><code>use Term::Cap;

$terminal = Term::Cap-&gt;Tgetent( { OSPEED =&gt; 9600 } );
$clear_string = $terminal-&gt;Tputs('cl');

print $clear_screen;
</code></pre>

On Windows, you can use the Win32::Console module. After creating an object for the output filehandle you want to affect, call the Cls method:

<pre><code>use Win32::Console;

$OUT = Win32::Console-&gt;new(STD_OUTPUT_HANDLE);
$OUT-&gt;Cls;
</code></pre>

If you have a command-line program that does the job, you can call it in backticks to capture whatever it outputs so you can use it later:

<pre><code>$clear_string = `clear`;

print $clear_string;
</code></pre>

blocks|key|3971848|text|如果您正在谈论终端，我会使用类似于Curses+lib的东西来实现它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3971849|有一个很好的Curses模块可以访问它，您可以像这样使用它：|3971850|perl+-MCurses+-e+'$win=new+Curses;$win->clear()'|code-block|syntax|javascript|3971851|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

If you are talking about a terminal, I would use something like the Curses lib to do it.

There is a nice Curses module to access it, which you can use like this:

<pre><code>perl -MCurses -e '$win=new Curses;$win-&gt;clear()'
</code></pre>

<pre><code>system($^O eq 'MSWin32'?'cls':'clear');

Ideally, something cross-platform.
