    // The SendReqExec method starts a command on the remote
    // server.   The syntax of the command string depends on the
    // default shell used on the remote server to run the command.
    // On Windows systems it is CMD.EXE.  On UNIX/Linux
    // systems the user's default shell is typically defined in /etc/password.

    // Here are some examples of command lines for <b>Windows SSH servers</b>:

    // Get a directory listing:
    Move "dir" To sCmd1

    // Do a nameserver lookup:
    Move "nslookup chilkatsoft.com" To sCmd2

    // List a specific directory.  Given that the shell is CMD.EXE, backslashes must
    // be used:
    Move "dir \temp" To sCmd3

    // Execute a sequence of commands.  The syntax for CMD.EXE may be found
    // here: http://technet.microsoft.com/en-us/library/bb490880.aspx.  Notice how the commands
    // are separated by "&&" and the entire command must be enclosed in quotes:
    Move '"cd \temp&&dir"' To sCmd4

    // Here are two examples of command lines for <b>Linux/UNIX SSH servers</b>:

    // Get a directory listing:
    Move "ls -l /tmp" To sCmd5

    // Run a series of commands (syntax may depend on your default shell):
    Move "cd /etc; ls -la" To sCmd6
