How do you comment out code in PowerShell?

Question

How do you comment out code in PowerShell (1.0 or 2.0)?

Answer 1

Single line comments start with a hash symbol, everything to the right of the # will be ignored:

# Comment Here

In PowerShell 2.0 and above multi-line block comments can be used:

<# 
  Multi 
  Line 
#> 

You could use block comments to embed comment text within a command:

Get-Content -Path <# configuration file #> C:\config.ini

Note: Because PowerShell supports Tab Completion you need to be careful about copying and pasting Space + TAB before comments.

Answer 2

You can make:

 (Some basic code) # Use "#" after a line and use:

 <#
    for more lines
    ...
    ...
    ...
    ..
    .
 #>

Answer 3

Use a hashtag followed by a white-space(!) for this:

 # comment here

Do not forget the whitespace here! Otherwise it can interfere with internal commands.

E.g. this is NOT a comment:

#requires -runasadmin

Answer 4

You use the hash mark like this

# This is a comment in Powershell

Wikipedia has a good page for keeping track of how to do comments in several popular languages
