Join Don Jones for an in-depth discussion in this video Use PowerShell comparison operators, part of PowerShell 3.0 for Administrators.
When you're trying to tell Power Shell…what objects you want to leave in the pipeline…and what objects you want removed from…the pipeline, you typically do that by having it…examine the objects and compare them to something,…and that's where comparison operators…come into play.…Help, star, operate, star.…We can see there's a help topic called…"About Comparison Operators",…so we'll just ask to see that.…Out, comparison.…
I don't really feel like typing all that.…Let's just end it with a star and see if that's…enough for Power Shell to pull it up.…It was.…Good.…Blah, blah, blah.…Lots of text.…There we go.…I knew there'd be a list of comparison operators…at some point.…So these are Power Shell's comparison operators.…You've got minus EQ for quality, minus NE for…not equals, minus GT for greater than or equal to,…and in fact, you know what, it's really cool…that Power Shell lets us play with these right…on the command line.…
We don't just have to read about them.…Is five equal to five?…Yes.…Is it equal to 50?…No.…Is hello equal to HELLO?…
