How to run a bash or shell script in a remote linux server using perl script and ssh

Question

I want to run a perl script on a remote server, it should login to a linux server via ssh and run a shell script with an argument, then print the results, please help......

I have a small script which will login and execute the ls command on the remote host, but i want to run a bash script instead.

use Net::SSH::Perl;

my $host = "xxxxx";
my $usr = "xxx";
my $pwd = "xxx";
my $ssh = Net::SSH::Perl->new($host);
$ssh->login($usr,$pwd);
my($stdout, $stderr, $exit) = $ssh->cmd("ls -l");
print "$stdout\n";

How can I execute the remote shell script instead of "ls -l"?

You run any remote command the same way... $ssh->cmd('whatever'); Doesn't matter what language whatever is implemented in. You might have to include a path if it's not in the remote computer's normal one. — Shawn

Can you show the $stderr and $exit values for $ssh->cmd(' ./monitor status ') ? — Håkon Hægland

Well there you go. You have to get your program running correctly on the remote computer. Installing whatever package provides that missing library is a good first step. — Shawn

Your script is fine. Just replace

"ls -l"

with

"/path/to/my/script arg1 arg2"

Note 1 - It's a good idea to use a fully qualified path to your script on the remote.

Note 2 - arg1 and/or arg2 can be variables of course. $arg1 $arg2. If you're not using variables then there is no need for double quotes and you should use single quotes ' instead.
