PowerShell Comments

When you want to help others by providing the information about a code, then you must use the comments in that code.

Just like other programming or scripting languages, you can give the comments in a PowerShell for the documentation purpose.

In PowerShell, there are two types of comments:

  • Single-line Comment
  • Multiple-line comment or comment block

Single line comment

Single line comments are those comments in which you can type a hash symbol # at the beginning of each line. Everything to the right of the hash symbol will be ignored. If you write the multiple lines in a script, you had to use the hash # symbol at the starting of each line.

Syntax of Single line comment

The following are the two syntaxes for the single-line comment:


<Any Command or statement> # <Any comment>


# <Any comment> 
<Any Command or statement>


Example1: This example displays how to use the comment at the end of a line

PS C:\> get-childitem #this command displays the child items of the C: drive

Example2: This example displays how to use the comment before the code and at the end of any statement.

PS C:\> #This code is used to print the even numbers from 1 to 10
PS C:\> for($i = 1; $i -le 10; $i++) # This loop statement initialize variable from 1
and increment upto 10.
>> {
>> $x=$i%2
>> if($x -eq 0) # The if condition checks that the value of variable x is equalt to 
0, if yes then execute if body
>> {
>> echo $i # This statement prints the number which is divisibel by 2
>> }
>> }



Multiple line comment

With PowerShell 2.0 or above, multiple line comments or block comments have been introduced. To comment the multiple lines, put the <# symbol at the beginning of the first line and #> symbol at the end of the last line.

Syntax of multiple line comment

The following block displays the syntax of multiple line comment:

<# Multiple line Comment.........

Example: The following example describes how to use the multiple line comment in code.

PS C:\> <# This code is used to print the
>> factorial of a given number#>
PS C:\> $a=5
PS C:\> $fact=1
PS C:\> for ($i=$a;$i -ge 1;$i--)
>> {
>> $fact=$fact * $i;
>> }

Type the following command to display the output of above example:

PS C:\> $fact
