net::telnet not behaving as expected

tsk1979 has asked for the wisdom of the Perl Monks concerning the following question:

I am using Net::Telnet module with perl 5.8.5 In that I use the code

$t->cmd("cd $repositery/$arglist[$i]");
@uname_string = $t->cmd("uname -a");
print "We got the uname @uname_string\n";

The array @uname_string has nothing. However if I do a
print $t->cmd("uname -a"); it prints the uname
I also tried
($uname_string) = $t->cmd("uname -a");
@uname_string = $t->cmd('uname -a');
[download]

I also took the example from cpan where I do

@uname_string = $t->cmd("who");
[download]

but when I do print @uname_string, I get nothing. any ideas?

You should try `my $unamestring = $t->cmd("uname -a");` [download] instead. The example in the Net::Telnet documentation uses a command (who) that returns several lines, that's why it's using an array. But you don't need to, because you're running a command that returns only one line. By the way, would you have used "use strict" and "use warnings" ( as everybody should get used to ) you'd certainly receive an appropriate warning.	[reply] [d/l]

I tried $unamestring also, it got the value 1. I think it took it in scalar context	[reply]

then try `use Data::Dumper; print dumper \@unamestring` and check what's happening.	[reply] [d/l]
