I have some set of server and I want to write a code that can go to each server login as su and perform some command and redirect output of the command to the individual file.
The command is working fine in terminal.
1. To login as su: su - username (I have privilege so it won't ask for the password too in command line/terminal).
2. have one command ulimit > serverxyz.txt
I have write the perl script but I am unable to login as su and it just generate
Code:
#!/usr/bin/perl
my $file = $ARGV[0];
open SLIST, $file or die $!;
my @allserver = (<SLIST>);
foreach my $server (@allserver){
chomp($server);
`ssh $server su - username -c "ulimit " > $server`;
}
It Generate some message like standard in must be a tty along with below message.
Also I want to turn of this message, so it would be helpful if you can guide how can I avoid this message in output.
Code:

Reason: Output to code tags too
#!/usr/bin/perl
my $file = $ARGV[0];
open SLIST, $file or die $!;
my @allserver = (<SLIST>);
foreach my $server (@allserver){
chomp($server);
`ssh -n $server su - username -c "ulimit" > $server\_limit`;
}
That message may be /etc/issue or /etc/motd, and there is a chance to suppress it within the configuration file /etc/login.defs.
Look also for hushlogin.
