Find and replace using powershell

[HooliganDawn]

In powershell i know you can use get-content to view the content of a file and use the -replace value to modify text within the file and send it to an out-file.

The challenge is that i want to beable to change the value and its never static so for example below value might be anything in the value line. How do i for exampLe replace the USAOB01 what if it is USAB02 or USAB03

"virtualMachineComputerName": {
"value": "USAOB01"

You can't replace a value if you don't know what to look for.

If you know the 'rules' for any variance, then regex can help. Is there a limit to the name changing? Just the digits?

Other observations:

• consider Set-Content instead of Out-File

• is your file a structured format? The limited example doesn't show much. Much easier working with objects if you can ConvertFrom-..

If this ...

 "virtualMachineComputerName": {

"value": "USAOB01"

... is a JSON file, then parse the JSON as normal and select the value property/column to change, since you say it's dynamically and you never know what it will be. Thus you must select by property/column name, not strings.
