===Scripting===

A pattern in many [[scripting language]]s is to delimit a line comment with <code>#</code> and provide no support for a block comment. Notable languages include: [[Bash (Unix shell)|Bash]], [[Raku (programming language)|Raku]], [[Perl]], [[Windows PowerShell|PowerShell]], [[Python (programming language)|Python]] and [[R (programming language)|R]].

An example in R:

Line 423:

...

}

</syntaxhighlight>

====Block in PowerShell====

PowerShell supports a block comment delimited by <code><#</code> and <code>#></code>. For example:

<syntaxhighlight lang="powershell">

# Single line comment

<# Multi

Line

Comment #>

</syntaxhighlight>

Line 742 ⟶ 753:

}

</syntaxhighlight>

====PowerShell====

Comments in [[Windows PowerShell]]

<syntaxhighlight lang="powershell">

# Single line comment

Write-Host "Hello, World!"

<# Multi

Line

Comment #>

Write-Host "Goodbye, world!"

</syntaxhighlight>
