Check If a String Contains a Specific Word
To check if the PowerShell string contains a specific word, we can use the string method Contains(). For example,
Example
PS C:\> $str = 'TestNZ01LT' PS C:\> $str.Contains('NZ') True
Now the funny thing is, even if the PowerShell is case-Insensitive, the above command is not. We need to provide the exact substring. For example, the below output will be false.
Example
PS C:\> $str.Contains('Nz') False
To overcome this problem, we can either provide the same search name in the method or we need to use the lowercase or uppercase method if you don’t want the search case-sensitive.
PS C:\> $str = 'TestNZ01LT' PS C:\> ($str.ToLower()).Contains(('Nz').ToLower()) True PS C:\> ($str.ToUpper()).Contains(('Nz').ToUpper()) True
