If you are working with dollar signs in PowerShell, then you might understand the problem of dealing with special characters like the dollar sign ($). In this tutorial, I will explain different methods to escape dollar signs in PowerShell with examples.
To escape a dollar sign in PowerShell, you can use the backtick character (). The backtick serves as an escape character, allowing you to include a literal dollar sign in your string. For example, you can write Write-Host “The total cost is $100.” to correctly display “The total cost is $100.” without PowerShell interpreting $100 as a variable. This method ensures that the dollar sign is treated as a regular character within the string.
Escape Dollar Signs in PowerShell
In PowerShell, the dollar sign ($) is used to denote variables. For instance, $name is a variable that can hold a value. However, when you need to include a literal dollar sign in a string, you must escape it to prevent PowerShell from treating it as a variable.
Method 1: Using the Backtick (`)
The backtick ( `) is the escape character in PowerShell. You can use it to escape the dollar sign and other special characters.
Syntax
`$Example
Let me show you an example.
Let’s say you want to print a string that includes a dollar sign, like a price.
Write-Host "The total cost is `$100."This will output:
The total cost is $100.I executed the above PowerShell script using VS code, and you can see the output in the screenshot below:

Method 2: Using Single Quotes
Another way to handle dollar signs is by using single quotes ('). Single quotes create a literal string, meaning that variables and special characters inside the quotes are not expanded.
Syntax
'string with $'Example
Here is an example.
Write-Host 'The total cost is $100.'This will also output:
The total cost is $100.Here is the output in the screenshot below:

Method 3: Double Quotes with Backtick
If you need to include both variables and literal dollar signs in a string in PowerShell, you can combine double quotes with the backtick.
Syntax
"string with `$ and $variable"Example
Here is an example.
$price = 100
Write-Host "The total cost is `$${price}."This will output:
The total cost is $100.Here is the exact output you can see in the screenshot below:
