How to Extract a Substring Using PowerShell?
These approaches can be used to resolve the above query.
Method 1: Extract a Substring in PowerShell Using “Substring()” Method
The “Substring()” method or function can be utilized to extract a substring. To do so, specify the indexing location in the parentheses, which start from “0”.
This example will demonstrate to extract a substring in PowerShell by utilizing the “Substring()” method:
In the above-mentioned code:
- First, we have assigned a string to a variable “$str1”.
- Then, concatenate the string-assigned variable with the “Substring()” method and pass
the starting and ending values separated by commas:
The specified string has been extracted from a string.
Method 2: Extract a Substring Using the “Length” Property in PowerShell
Another way of extracting a substring from a string is by using the “Length” property. It is utilized in order to extract the string’s last characters. For instance, go through the below example.
Execute the following code in PowerShell terminal:
> $str.Substring($str.Length -10)
In the given code, we simply specified the “$str.Length” parameter inside the “Substring()” method and assigned a number to extract a substring from a string:
It can be observed that the substring has been extracted from a string using a “Length” property
The substring can be extracted from a substring in PowerShell using multiple approaches. These approaches include the “Substring()” method or function and the “Length” property. Both of these approaches extract the substring from a string using the character’s indexing numbers. This post has illustrated a complete procedure to extract a substring using PowerShell.
