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.
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`"" 
-match, Select-String) and wildcard matches (-like) are not the same and do not use the same patterns.To complement Ansgar Wiechers' helpful answer, which contains the correct solution:
Given that " is not a regex metacharacter (has no special meaning in a regular expression), your question boils down to:
How can I embed a " (double quote) in a string in PowerShell?.
[ is a regex metacharacter, so it must be escaped as \[ inside a regex in order to be treated as a literal. As TheIncorrigible1 points out, you can let [regex]::Escape($string) handle that escaping for you; the result treats the content of $string literally in the context of a regex.There are several options, demonstrated here with a simplified sample string, 3 " of rain - see also: Get-Help about_Quoting_Rules:
# Inside a *literal string* ('...'): # The content of single-quoted strings is treated *literally*. # Double quotes can be embedded as-is. '3 " of rain' # Inside an *expandable string* ("..."): # Such double-quoted strings are subject to *expansion* (interpolation) # of embedded variable references ("$var") and expressions ("$(Get-Date)") # Use `" inside double quotes; ` is PowerShell's escape character. "3 `" of rain" #" # Inside "...", "" works too. "3 "" of rain" # Inside a *literal here-string* (multiline; end delimiter MUST be # at the very beginning of a line): # " can be embedded as-is. @' 3 " of rain '@ # Inside an *expanding here-string*: # " can be embedded as-is, too. @" 3 " of rain "@ For the sake of completeness: you can create a double quote via its Unicode code point (the number that identifies each character), which is 0x22 (hex) / 34 (decimal), by casting it to [char], e.g.: [char] 0x22.
You can use this:
'3 ' + [char] 0x22 + ' of rain'-f operator: '3 {0} of rain' -f [char] 0x22
