Maybe you could store the output of the hosts command into an array and then loop over the array to issue your ssh instruction.

Also, rather than storing the output of the ssh command into a file, it might be simpler to issue the command with backticks and store the result into a variable. Something like this (untested): 

my $uptime_output = `ssh $_ 'uptime'`;

(I don't know whether you need redirection in the ssh command. I would assume the output should come on STDOUT.)
