How to use String Contains in PowerShell

To check if a string contains a specific substring in PowerShell, you can use the -Contains operator.

This operator allows you to check if a string contains a given substring, and returns $true if it does, or $false if it does not.

Examples

Here is an example of how to use the -Contains operator in PowerShell:

$myString = "Hello world"

if ($myString -Contains "world") {
    Write-Host "The string contains the substring."
} else {
    Write-Host "The string does not contain the substring."
}

In this example, the if statement uses the -Contains operator to check if the $myString variable contains the substring "world".

If it does, the code inside the if block will be executed, and a message will be output to the screen. If it does not, the code inside the else block will be executed, and a different message will be output to the screen.

You can also use the -Contains operator in a script to check if a string contains a substring and take a specific action based on the result.

For example, the following code checks if a string contains the substring "world", and outputs a message if it does:

$myString = "Hello world"

if ($myString -Contains "world") {
Write-Host "The string contains the substring 'world'."
}

Conclusion

To check if a string contains a specific substring in PowerShell, you can use the -Contains operator.
