From: PerlFAQ Server on 4 Aug 2010 06:00 This is an excerpt from the latest version perlfaq8.pod, which comes with the standard Perl distribution. These postings aim to reduce the number of repeated questions as well as allow the community to review and update the answers. The latest version of the complete perlfaq is at http://faq.perl.org . -------------------------------------------------------------------- 8.7: How do I clear the screen? (contributed by brian d foy) 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): use Term::ANSIScreen qw(cls); my $clear_screen = cls(); print $clear_screen; 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: use Term::Cap; $terminal = Term::Cap->Tgetent( { OSPEED => 9600 } ); $clear_string = $terminal->Tputs('cl'); print $clear_screen; 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: Win32::Console; $OUT = Win32::Console->new(STD_OUTPUT_HANDLE); my $clear_string = $OUT->Cls; print $clear_screen; 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: $clear_string = `clear`; print $clear_string; -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq.
