 Basic of PowerShell-Part 1

PowerShell is a scripting language. It helps to automate the technical tasks like generate daily client reports. Going to start a series  of  blogs to share the basic understanding of PowerShell for the beginners.  This is the Part-1 in which we will cover the below given points.

1- Define the variable- $ is used to define the variable 

2- Comment the single line-  # is used to comment the single line

3- Comment the Multiple lines- <# content #>  is used to comment the multiple lines

4- Use of  Write-Host- Write-host is used to print the outcome or print the any message

5- Use of  Read-Host-  Read-host is used to take run time input from the User. it returns the datatype string.

6- Covert the datatype- To convert the datatype, use syntax like [Int]$stringvaribale. it will convert the string value into the int.

To understand the above, we will take a example of  'Add two numbers'.

PowerShell Script-1

#write the PowerShell script to add the number

#Add the two numbers

<#write the PowerShell script to add the number

Add the two numbers#>

#define the variable

 $num1= 5

 $num2= 6

 $TotalSum = $num1 + $num2

 Write-Host 'Total Sum:'$TotalSum'

Output of this script- Total Sum: 11

PowerShell Script-2 

 # use of Read-Host and Convert the variable into Int

 $num1= Read-Host 'Inter the First Number'

 $num2= Read-Host 'Inter the Second Number'

 $TotalSum = [Int]$num1 + [Int]$num2

 Write-Host 'Total Sum:$TotalSum'

Output of this script- User need to inter first number and second number at runtime.
