System Administration Automation
The system administration task involves configuration and maintenance of computing installations using different languages. The work has become more efficient due to the introduction of the new automated tools that support the process. The visual basic script language is an active computing configuration language with an interpreter that is capable of supporting the systems automation (Ford Jr, 2014). Automating systems is a daunting task and the people involved have to be aware of the processes to implement effectively an automated system, identify the system requirements and properly install them (O'Neill, Rosen, & Stanek, 2011). Relevant set boxes and the internet are used currently to roll out systems and efficiently assist in pre-installing all necessary requirements before the system is rolled out.
While automating a system, variables must be defined, and proper description of constants and data types given taking into consideration both the input and the output factors (Ford Jr, 2014). The ultimate expected results and the requirements to achieve in the system automation task must inform the whole process to attain an automated system. The structures and the arrays require partitioning and must depict an adequately functional automated system (Ford Jr, 2014). Permissions, links, and mounting devices of the systems are described and handling files and directories explicitly defined to perform functions. Configure the system, protocols, and network must be in a desirable layout. The process must be controllable, and the automation must have the capacity to handle the bulk in place (O'Neill, Rosen, & Stanek, 2011).
There are different inputs and output methods that can be related to the visual basics and that are necessary for the automation process. The methods range from the clear, raise, writeline, write, test, replace and execute methods within the script (Dixit& Singh, 2013). It is all about executing a command to give intended results in terms of output. The methods must be supported by the file systems created each varying with its function. Every statement input in the system produces an output and the system can be matched, or integration done by other systems.
VBScript Input Methods
The scripts designing should be in a way that they interact with end-users on the interfaces. Prompting of user inputs are from the commands that create the desired fields of the output. The system invokes a function that supports the input (InputBox) that brings about a dialogue box (Dixit & Singh, 2013). The dialogue box comes about with fields with which a user can enter texts and then select either of the command buttons to execute a function. The Input Box has the parameter of ‘prompt’, which is a characteristic necessary for the defining the message on the dialogue box (Jones, 2007). The ‘title’ parameter on another hand represents the text in the title bar for the interface. ‘Default’ is an input parameter that defines the default figures in the box among other optional parameters (Jones, 2007).
In the omission of optional parameters, the default commands are executed to initiate outputs. The dialogue box has different buttons that gives respective results when the box is closed and the result values are verified by ‘if’ statements (Dixit & Singh, 2013) while constants and strings streams and split results as desired in the outputs. The inputs to the system come from a graphical interface in a command line and executed to give the results. Combinations of the methods are necessary to avoid a return of error and achieve the results intended (Jones, 2007). The automation process should be able to combine the methods in a way that the commands will be executed fast and efficiently to give results promptly with less effort. When a script name is entered on the command line, the default hosts run the entry, and such must be highly verified to ensure proper results. Therefore, the input function of the VBscript only allows for obtaining of results from the executed values by the users.
VBScript Output Methods
There are different interactions and methods engaged to get an output using the VBScript. There are various ways that a systems administrator can use in displaying outputs using the VBScript. After the texts executed are processed by the host, the ‘Echo ()’ shows the message in windows or popups (Jones, 2007). The results can also be presented by ‘Popup ()’ that would create a chance to toggle the icons and buttons displayed while returning the value of the button pressed at the same time. The Echo () method displays amessage depending on the execution and the processing of the values entered (Dixit & Singh, 2013). It, however, cannot collect user inputs and must work in a combination with output-input methods in a standard way.
The standard input and output streams must interact in a default or specified manner, and all the inputs received from entries while displaying all the errors and the output on Windows. The supplied characters are displayed on the screen by ‘write’ parameter, with ‘Write Line’ writing on the screen and append a carriage return (Jones, 2007). The ‘Write Blank Lines’ is then the parameter responsible for the blanks on the display windows (Dixit & Singh, 2013). The combinations of methods hand in hand and interconnections are in a way that one accomplishes another. Failure to insert the correct method, a default can be fetched or the return in error is achieved without results (Dixit & Singh, 2013). The system automatons must then define variables and parameters, identify requirements and execute a function in a complete manner for the intended purposes.
