Regex pattern with embedded double quotes in PowerShell

Question

Following keyword need to be searched on document using PowerShell:

["Allowed Acquisition Clean-Up Period" 

$keyword = ""
Get-Content $SourceFileName | Select-String -Pattern $keyword

String which I'm searching for has double quotes in it, so I'm struggling how to mention in this $keyword.

Answer 1

Apparently you not only have double quotes, but also an opening square bracket. Square brackets are meta-characters in regular expressions (for defining character classes), so you need to escape those too.

Define your expression in single quotes:

$keyword = '\["Allowed Acquisition Clean-Up Period"'

or escape nested double quotes with backticks:

$keyword = "\[`"Allowed Acquisition Clean-Up Period`""
