Selecting strings and case sensitivity

Question

I am trying to filter for an object that has a Title field, and I want to ignore case. Is there a way to make sure case sensitivity if turned off?

| Where-Object {$_.Title -like "myString"} 

Answer 1

PowerShell is fundamentally case insensitive (e.g. "HEy" -like "hey" is True).

If you want to use the case sensitive version of like, use -clike.

Answer 2

By default case sensitivity is off:

PS> 'test','TEST','TeSt','notest' | ? { $_ -like 'test' } test TEST TeSt 

From documentation:

By default, all comparison operators are case-insensitive. To make a comparison operator case-sensitive, precede the operator name with a "c". For example, the case-sensitive version of "-eq" is "-ceq". To make the case-insensitivity explicit, precede the operator with an "i". For example, the explicitly case-insensitive version of "-eq" is "-ieq".
