We will go through all the important aspects which you should know to learn PowerShell. PowerShell first version 1. Today, PowerShell is at version 7. Next in this Powershell scripting tutorial, we will learn about features of Powershell.
PowerShell is pre-installed in all latest versions of Windows. We need to launch PowerShell for that we need to follow the given steps:. Step 2 Power Shell Window Opens. A cmdlet which is also called Command let is a is a lightweight command used in the Window base PowerShell environment. PowerShell invokes these cmdlets in the command prompt. Cmdlets are different from commands in other command-shell environments in the following manners? A cmdlet is a series of commands, which is more than one line, stored in a text file with a.
A cmdlet always consists of a verb and a noun, separated with a hyphen. Some of the verbs use for you to learn PowerShell is:. Powershell scripts are store in. This protects your system from accidental harm. To execute a script:. Moreover, there is a policy which restricts script execution. You can see this policy by running the Get-ExecutionPolicy command. Step 1 Open an elevated PowerShell prompt.
You can do multiline editing, syntax coloring, tab completion, selective execution and lots of other things. PowerShell more potent than command editor. Basically for Loop is used to execute the block of statement repeatedly when the condition is true. In the above script I have taken one array variable arrayItem and store some value to the arrayvariable. Up to the condition is true the block of code will execute. The code will stop executing when the condition is false. In the below script I have added one for each loop example.
I have declared a variable ArrayList and assign some value to the variable. If the condition is true then go for the code to be executed then increment the counter value to one. We all know the if statement is nothing but a collection of boolen expression. We know the boolen statement has only two value either true or false.
In the if statemnet if the condition is true then block of code which is inside the curly bracket will execute. The code will not execute if the condition is false. In the if else statement when the condition is true then go for the block of code of if part otherwise goes to else part and execute the block of code or else part.
In the below example we checked x is less than equal to y. The statement is false so we need to go for else part. First I have checked if x is not equal to y. Else if I have checked that if x value is higher than equal to y. In the nested if ststement we can place a if statement or if else ststement inside a other if statement and if else statement. I have checked if x greater than y then go for inside if statement and check if x greater than z.
Switch statement is nothing but a series of if statement. This statement is used for checking multiple condition. We can understand better by the below example. The one value is Winter. The output value will store in the Result variable.
It will print the result value. PowerShell Array is designed to store a collection of the same type of item or a different type of item. In the PowerShell array no datatype is mentioned then the PowerShell creates each array as an object array.
Display all the Array element: 1 2 3 4 5 6 7 8 Get the length of array: 8 Get fourth element of array 4 Get partial array print subList 2 3 4 using for loop 1 2 3 4 5 6 7 8 Assign values 1 10 3 4 5 6 7 8.
Alias is nothing but an alternative name for cmdlets. In the below example I have created a new name for Get-Help cmdlets. In PowerShell, some default shortcut name or alias is there. We can able to know all the shortcut cmdlets by using Get-alias cmdlets.
Hashtables is nothing but an array but we can store paired key and value. Basically, the object that is used as a key, and the value that you want to be linked to that key.
A function in PowerShell is a block of code has a name assign by the user. We can use the function multiple times in code. We need not write the code again and again. We can call the function in a program whenever required. The split operator is used to split the string value.
The below example is split of a string value. In the below example we will discuss how to join the string value. To join multiple value join opearator is used. To convert an integer value to binary in the ToString function pass two parameter one number which we want to convert and 2.
I have set the size and Start position of form. I have let the button size defult and then add the button to form controls collection and finally call to ShowDialog method and store in Dialouge variable. Previously when we want any information about the disks we need to open the CMD window and use disk part.
In the below script I have explained how to take a screenshot in our system using PowerShell cmdlets. Step First Get the screen information means property of screens like height, width, and co-ordinates.
We need to configure the area up to which area we want to copy the screen. Virtual Screen property is used to get all the property of screen which we want to take the screenshot. In step-2 we need to create a new object named as BitmapObject. For the BitmapObject specify screen height and screen width. The Graphics class is used to draw the BitmapObject. This Graphics object is used to capture the screen.
We need to set the co-ordination. We have dclare a file variable and store the file location where we want to store the capture screen. I want to save the file innewscreenshot So I have to give the address of the file. When we are doing any kind of operation with different datatype value then the casting concept arises.
It will convert the data type. One variable is string type and other variable is double type. So when we will get for sum value we will get error. When we want to create a new printer to the system we need to mention the value of the parameter. The parameters are.
