Hi,

Is there any solution to run shell with out using crontab or any other schedulers.

I mean, I want activate shell script from Batch file.

Thanks in advance.

If assume you mean, run a unix-style shell script from a WinNT Command Prompt (not really a 16-bit MSDOS session?)

Yes, there are some free and commerical version of popular Unix shells (and the assorted commands) for WinNT.  I've been using MKS Toolkit for many years.  Kinda expensive, but very complete set of Unix tools.

In order to execute a program or script on the remote unix box you will need to use ssh which should be running on your unix box.  On the windows side, you will connect using a little util that comes with the PuTTY terminal client.  Grab the windows installer from

Instructions for how to use plink are here:

</a>

Basicaly you would just call plink right after your ftp commands are done with.  Remember that you can string commands together with && at least in the bash shell.  Using && instead of ; makes sure that everything finishes successfully before the next command is executed.

I stand by my initial recomendations.

Here's some aditional advice for the archives:

Another possible way of doing this is to write a script in perl (or python maybe) that implements a telnet or ssh client.  In perl I've used the Net::Telnet module and it's not to hard to set up a connection and have it run a command or two.  Basicaly do something like this:

[code]
use Net::Telnet();

$timeout  = "240";  # About how many seconds command takes to run
$prompt  = '/WhatTheShellPromptLooksLike/'; # single quotes works best
$cmd       = "/path/to/shellScript";

# Set up the session
$telnet = new Net::Telnet();

# Initiate the connection
$telnet->open("$host");

# Send our command
@output = $telnet->cmd(String    => "$cmd",
                                     Prompt  => "$prompt",
                                     Timeout => "$timeout");
# Close Session
$telnet->close();
[/code]

Note that the array "@output" contains what your command outputs so you will probably want to parse that to see if the command was successful or not.  I'm sure there's a module to do a similar action via ssh instead of telnet.
