exit status of remote commands

[Ironhide]

Hi,

I want to execute some commands on a remote machine through ssh and
get back their results; would ideally like get back the
1. exit status of the command executed remotely
2. stdout
3. stderr

All this I would like to do inside a perl script and get all of the
above 3 in 3 separate variables.
Can this be done?

p.s.: I have already tried the Net::SSH module; would be helpful if
you guys could suggest me other ways of doing this.

Well, the obvious way is to run ssh(1) with something like IPC::Run...

What was your problem with Net::SSH?

Try using IPC::Open3;

my($wtr, $rdr, $err);
$pid = open3($wtr, $rdr, $err, 'ssh user@host cmd')

# Work with the filehandles $wtr, $rdr and $err

waitpid($pid);
$exit = $? >> 8;

if $exit is 255 the error might be an error with the ssh command and
not you remote command. Otherwise it should be the exit status of you
remote command.

What was wrong with Net::SSH? If you don't tell us what you found
unsuitable about Net::SSH, then how are we to know whether some other
module we might recommend suffers the same problem or not?
