Net::SSH::Any does not return output for few specific commands

[magic_007]

A newbie to Perl. I was trying to use Net::SSH::Any module to execute some commands on Linux box from my perl code and get the output. It works fine but for few commands.

use Net::SSH::Any;

$ssh = Net::SSH::Any->new($hostname, user => $username, password => $p
+assword);
$out = $ssh->capture(“who am I”);
print $out;

Result: No output @ all. “Who am I” command doesn’t return anything. Please let me know if I'm missing something here"

Add error checks:

$ssh = Net::SSH::Any->new($hostname, user => $username, password => $p
+assword);
$ssh->error and die "unable to connect to remote host: " . $ssh->error
+;
$out = $ssh->capture(“who am I”);
$ssh->error and die "remote command failed: " . $ssh->error;
print $out;

Thanks Salva for quick reply. I added error check but no break. The code is connecting to the host it did not die and the $ssh->error is printing 0.

My problem got solved. Instead of "who am i" I used "whoami" and i got the output.

I even tried "who -am -u" but it did not work but i could not find out why capture doesn't return output for those commands.

Thanks anyways.
