Hi Monks,
I want to execute a script on a remote UNIX box. Lets say this script will create an user in Oracle server ( which is in Unix box). I want my "rsh" implementation can handle all types of error. I have found out which types of error may arrive. These are:

"rsh" command itself fails i.e. in the remote Unix box there is no equivalent user or ".rhosts" file.
During execution of command using "rsh" command any error is occured and I want to analyse this error.
"rsh" command will wait for a certain time and after that if it can not execute it will proceed further i.e. timeout option with "rsh".

I have written following wrapper code for "rsh" which can handle above mentioned 1 and 2 types of errors.

       #Get the machine OS 
       $OS=$^O;

    if ($OS=~ /hpux/i) 
    {
        $Command = "remsh" . " <MachineName>" . " <Command>";
    }
    else
    {
        $Command = "rsh" . " <MachineName>" . " <Command>";
    }
    
    #Creating temporary file
    $ErrorFile = "tmp".$$;
    
    $Error = 0xffff & system("($Command  2>$ErrorFile)");
    
    # Open the error file and see if it has some contents
    if( open (fhError, "< $ErrorFile")) 
    {
        while (<fhError>) 
        {
            $ErrorText .= $_;
        }
         $Length = scalar(split(//,$ErrorText));
        if($Length != 0 ) 
        {
            print "Error occured during the execution of rsh command";
            close (fhError);
            unlink ($ErrorFile);
            die "\n";
        }
        else 
        {
            close (fhError);
        }
    }
    unlink ($ErrorFile);

    if ($Error != 0 ) 
    {
        die "Error occured during the execution of rsh command\n";
    }

Is there any way to implement time out option?
Any help really appreciated.
Thanks in advance.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
