Question

I found some strange behavior in PowerShell, and can't figure out why it behaves this way. Out of the three following lines of code, why is it that only -match returns what I want, and the other two commands return nothing?

Get-Service | ?{$_.Name -like "sql"}
Get-Service | ?{$_.Name.Contains("sql")}
Get-Service | ?{$_.Name -match "sql"}      # This one works?

-like uses a wildcard match. If you don't use any wildcards, it will do an exact match (not case-sensitive).

The .Contains method of the [String] object is case-sensitive.

The -match operator uses a regular expression (not case-sensitive). Since the input string (the name of the service) exists in your pattern, it returns $true.
