Filtering Objects with Where-Object Using Contains in PowerShell

In PowerShell, you can use the Where-Object cmdlet with the -contains operator to filter a collection based on whether a property contains a certain value.

The following method shows how you can do it with syntax.

Method 1: Filter elements containing the string using Where-Object

$languages = @("Python", "C#", "C", "C++", "VB", "Java", "Go")
$result = $languages | Where-Object {$_ -contains "C++"}

$result

This example will filter out elements that contain the string “C++” and display the result on the terminal.

The following example shows how you can use this method.

Use Where-Object to Filter Elements Containing String

The following PowerShell script shows how you can do it.

# Define the list of languages
$languages = @("Python", "C#", "C", "C++", "VB", "Java", "Go")

# Use where-object to filter elements containing "C++"
$result = $languages | Where-Object {$_ -contains "C++"}

# Output the result
$result

Output:

In this example, we have defined a collection $languages that contains the list of programming languages.

We then pipe the $languages to the Where-Object cmdlet to filter out elements that contain the string “C++” using the -contains operator, and the result is stored in the $result variable.

Finally, the filtered result is printed.

Conclusion

I hope the above article on using the Where-Object cmdlet with -contains operator to filter a list based on the condition specified is helpful to you.
