Description:

I need to know if it's possible to print encode blanks or some other types of character while sending password to expect FH. If so, how? Thanks for your input.

sub copyover { my $scp=Expect->spawn("/usr/bin/scp -r \"$srcpath\" ${dest_hos +t}:$destpath"); my $spawn_ok; $scp->expect(30, [ qr'ssword: ', sub { $spawn_ok=1; print $scp ("password\n"); exp_continue; } ], [ qr'yes/no', sub { $spawn_ok=1; $scp->send("yes\n"); exp_continue; } ], '-re', qr'[#>:] $', #' ); $scp->soft_close(); return; }

I think you want:

[ qr'ssword: ', sub { $spawn_ok=1; $scp->stty('-echo'); # echo off print $scp ("password\n"); $scp->stty('echo'); # echo on exp_continue; } ],

(untested, don't have Expect installed)

Update: that might need to be $scp->slave_pty->stty('-echo') and $scp->slave_pty->stty('echo'). or you might need to use one of the $obj->log_* or Expect::Log_* function/variables to tweak what gets displayed where and when.
