Below is a script in perl what i want to do it to login to a host, run a few commands, but don't want to use mutilple ssh session, i want it to be done in one ssh session itself, it should check the OS (Linux/Solaris) and then run the commands appropriately and print the output in below format. hostname:domainname:OS Release version Right now, i am able to login to the box but am not able to collect the output, i get the output but the output comes line by line. 
#!/usr/bin/perl
#use strict;
use warnings;

# Checking details of the host. Domainname and the OS version will be 
+checked.

my $SSH = '/usr/bin/ssh -o StrictHostKeyChecking=no' ;
my $DOMAIN = '/bin/domainname';
my $LINUXOS = 'cat /etc/redhat-release';
my $UNIXOS = '/bin/uname -sr';

print "Enter the filename: ";
chomp($HOSTLIST = <STDIN>);

open HOSTS, $HOSTLIST or die "can't open the file: $!\n" ;

foreach my $host (<HOSTS>) {
chop($host); # if i do not use chop, ? comes in the ssh command.
@details = qx($SSH $host $DOMAIN; $LINUXOS);
print @details;
}

1. Please help me to run the commands in one ssh session only, i know other way to do it by creating another script and calling it from the ssh command, but don't want like that.

2. How can i put checks while logged into the system and runnign the command, for particular system(in my case Linux/Solaris).

3. How the formatting of the output can be done, instead of it coming line by line.
