PowerShell is a powerful tool that can be used to automate tasks on your computer. One of the many things it can do is replace text in a string. For example, you might want to update all instances of “dog” with “cat”. It can use regular expressions to find and replace all occurrences of “dog” with “cat”, for example.
A PowerShell “method” (also known as a built-in function) is a collection of commands that enable you to perform an action on an object. For example, a string is an object that I can run against a function that counts how many characters it has.
Now that we know what a method is, we will use the replace() method to replace a text string.
The following code example will replace the string shell with the sting PowerShell. to test the code, copy it and run it.
$mystring = "I love Shell" $newstring = $mystring.Replace("Shell", "PowerShell") $newstring
the output will look like this:
I love PowerShell
We can also use the -replace switch for more advanced scenarios.
$string1 = "my shell" $string1 = $string1 -replace "shell", "powershell" $string1
The output will look like this:
