Hi monks, I have a problem that I want to append an expression to a file on a remote host.I am wriiting a subroutine in a script and i want that subroutine to open a file on a remote host and append an expression.I want to do it through rsh and rcp...is it possible???

Try File::Remote

I think it could be something like (not tested):

use Net::SSH::Perl;

my $host = 'host';
my $user = 'username';
my $pass = 'password';

my $string = 'Expression to append';
my $cmd = "echo $string >> /path/to/file"; 

my $ssh = Net::SSH::Perl->new($host);
$ssh->login($user, $pass);
my($stdout, $stderr, $exit) = $ssh->cmd($cmd);

What kind of expression?

Could we see your first attempt?

Use SSH and SCP instead of RSH/RCP though.

Although I have not used them, I remember having noticed in the documentation for Net::SFTP that it provides methods for opening remote files. I wouldn't use rsh and rcp in any case, as far as my opinion is concerned...

Possible it is indeed.

Hi, If you have access to the remote machine you can use a simple open method.
you can go through this code and have some idea....
Authentication of the remote is also should be there....


    $hostname ="testing";#it may be ip address or remote host name
    $hostfilename="temp\fooo.ini";
    $hostfilename =~ s/\\/\\\\/g;
    my $file="\\\\$hostname\\$hostfilename";
    if(!-f $remotepath){
        print "Remote access and add content to remote file\t\Failed";
        exit;
    }
    else{
        #Remote file access
        open(TEMP,">>$file") or die ("cannot open the remote file '$fi
+le':$!");
    

        #Here add your stuff to append data to the remote file
        close(TEMP);
        
    }
