Alice got promoted so we need to change her department to Senior Leadership. The object can then be modified easily like any other object. The object can then be exported back out using ConvertTo-Json. This gives a test. I like to use this simple function to fix my JSON for me. Simply run the following to fix the json file:.

You can remove contained items using Remove-Item , but you will be prompted to confirm the removal if the item contains anything else. If you do not want to be prompted for each contained item, specify the Recurse parameter:. You can also map a local folder, using the New-PSDrive command. The following command creates a local drive P: rooted in the local Program Files directory, visible only from the PowerShell session:.

Just as with network drives, drives mapped within Windows PowerShell are immediately visible to the Windows PowerShell shell. In order to create a mapped drive visible from File Explorer, the parameter -Persist is needed.

However, only remote paths can be used with Persist. One of the more common storage formats for text data is in a file with separate lines treated as distinct data elements. The Get-Content cmdlet can be used to read an entire file in one step, as shown here:.

Get-Content already treats the data read from the file as an array, with one element per line of file content.

We also looked at regular expression, a language used to describe patterns in text, and on the Select-String cmdlet, which makes heavy use of regular expression.

The substring starts at a specified character position and continues to the end of the string. Substring int startIndex, int length Retrieves a substring from this instance. The substring starts at a specified character position and has a specified length. IndexOf string value Reports the zero-based index of the first occurrence of the specified string in this instance.

IndexOf string value, int startIndex Reports the zero-based index of the first occurrence of the specified string in this instance. The search starts at a specified character position. LastIndexOf string value Reports the zero-based index of the last occurrence of the specified string in this instance.
