// 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:
ls_Cmd1 = "dir"

// Do a nameserver lookup:
ls_Cmd2 = "nslookup chilkatsoft.com"

// List a specific directory.  Given that the shell is CMD.EXE, backslashes must
// be used:
ls_Cmd3 = "dir \~temp"

// 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:
ls_Cmd4 = "~"cd \~temp&&dir~""

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

// Get a directory listing:
ls_Cmd5 = "ls -l /tmp"

// Run a series of commands (syntax may depend on your default shell):
ls_Cmd6 = "cd /etc; ls -la"

// Request a directory listing on the remote server:
// If your server is Windows, change the string from "ls" to "dir"
