Hi Igor,

After updating cygwin on my pc, i try again:

% perl -e 'system("stty raw -echo") ; print "\e[H\e[J"'

which doesn't clear the screen. 
I use the ActiveState Perl, 5.8.0, bash 2.05b.0(8) and cygwin-1.3.20-1.
Can you send me a command line which work? I will try it.

Many thanks,
Philippe

Redirecting to the correct list.  Please remove <cygwin-xfree at cygwin

And answering:

Philippe,

Works for me (using cygwin-1.3.20, bash-2.05b-8 and perl-5.6.1)...  You
might want to report your problem properly, as described in
<http://cygwin.com/bugs.html>.  Also, check that your perl one-liner
outputs exactly the right sequence (by piping it to "od -c", for example).
