execute multiple commands over ssh (without module)

[dsx]

is there a way to execute multiple ssh commands on a remote host and save each command output in a different scalar without using a module? i want execute all commands in the same ssh connection. i have tried to do something like that, but i don't know how to save the output in a scalar. is there a way to do that in this manner?

$check = <<'CMD';
for i in /home/*
do
echo $i
done
CMD
open(SSH, "| ssh sshtest\@localhost -T");
print SSH $check;
close(SSH) or die "$!";

Are core modules OK? If yes, check out IPC::Open3.

Yes, look inside the module to see how its done

or better yet, install the module

A Guide To Installing Modules

Yes, even you can use CPAN

in which module?

i have already tried the module net::ssh:expect. but i need the script on several servers (linux 32bit, linux 64bit, solaris) on which i have not root access. so i try to keep it simple and don't use any module and especially not the net::ssh:expect module which has a dependency on IO::Tty which uses a shared library (tty.so).

Try Net::OpenSSH, it's pure perl and doesn't require any other module (unless you want to use password authentication, in that case it also needs IO::Pty).
