How to throw an exception in PowerShell if the output of the previous command does not match the regular expression?

Question

PowerShell

For example, I want to make sure that the PHP version is exactly what I need and continue executing the script, otherwise throw an exception. I check like this:

Invoke-Expression "php -v" | Select-String -Pattern "PHP 7.4"

Further, as I understand it, there should be another pipe and a command that, if an empty string is received, will throw an exception, but I can’t find anything like it. Tell me how to do it.

Answer 1

Invoke Expression "php -v" | Where-Object {$_ -like "PHP 7.4"}
