That regular expression works fine. Thanks a lot.
However i am facing a new issue now. After ssh, I can encounter either RSA key authentication and password prompt(First time) or only password prompt. Then I want to be able to continue to look for bash prompt so that I can continue my other linux commands.Here is my code snippet
$exp->spawn("ssh -l root $sshHostname") or die "cannot spawn ssh: $!\n
+";
$exp->expect($timeout,[ qr/RSA/i,#/
sub { my $fh = shift;
$fh->send("yes\n");
});
$exp->expect($timeout,'-re','password' => sub { my $fh = shift;
$fh->send("$sshPWD\n");}
);
$exp->log_file->print("#Successfully ssh'ed in\n");
$exp->expect($timeout, '-re','~]#' => sub {my $fh = shift;
$fh->send("cd /u0x/tmp\n");}
