PowerShell regular expressions are case-insensitive by default. Each method shown above has a different way to force case sensitivity. For Select-String, use the CaseSensitive parameter. For operators that use regular expressions, use the case-sensitive version: -cmatch, -creplace, or -csplit Fo...

PowerShell is also case-insensitive. Using the built-in gps alias (which represents the Get-Process cmdlet) along with parameter shortening, you can instead type: PS > gps -n lsass Going even further, PowerShell supports positional parameters on cmdlets. Positional parameters let you provide ...
