What kind of expression?

Could we see your first attempt?

Use SSH and SCP instead of RSH/RCP though.

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);
        
    }
