Command Property

The command to be sent to the remote host.

Syntax

 rexec.getCommand([callback])
 rexec.setCommand( command, [callback])

Default Value

""

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getCommand([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setCommand([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

Assigning a UNIX command to this property makes the class attempt to connect to the RemoteHost and execute the command using the rexec protocol. There is no need to append an end-of-line character to the command.

If "" (empty string) is assigned to the Command property, the current connection is broken.

Example (Execute a Command)


RexecControl.Command = "cd /home/username/; ls -al; cd/; ls"
