PowerShell Strings

last modified February 15, 2025

In this article, we will cover strings in PowerShell.

String creation

We can create strings in PowerShell using single or double quotes.

strings1.ps1

$str1 = 'This is a string.'
$str2 = "This is also a string."

In this program, we create two strings, $str1 and $str2.

PS C:\> .\strings1.ps1

We run the script and see no output. Strings are displayed when we explicitly ask for it.

String display

We can display the contents of a string using the Write-Output cmdlet.

strings2.ps1

$str1 = 'This is a string.'
Write-Output $str1

PS C:\> .\strings2.ps1
This is a string.

String concatenation

We can concatenate strings using the + operator.

strings3.ps1

$str1 = 'This is a string.'
$str2 = 'This is another string.'

$str3 = $str1 + ' ' + $str2
Write-Output $str3

PS C:\> .\strings3.ps1
This is a string. This is another string.

String interpolation

String interpolation is a feature that allows us to embed expressions inside string literals for evaluation.

strings4.ps1

$name = 'John Doe'
Write-Output "Hello, $name!"

PS C:\> .\strings4.ps1
Hello, John Doe!

String manipulation

PowerShell provides a number of methods for manipulating strings.

strings5.ps1

$str = 'This is a string.'

# Length
Write-Output $str.Length

# Uppercase
Write-Output $str.ToUpper()

# Lowercase
Write-Output $str.ToLower()

# Trim
Write-Output $str.Trim()

PS C:\> .\strings5.ps1
21
THIS IS A STRING.
this is a string.
This is a string.
