Join Don Jones for an in-depth discussion in this video Name variables, part of PowerShell 3.0 for Administrators.
In PowerShell variable names,…typically consist of letters, numbers,…and the underscore character.…They're typically seen prefixed by a dollar sign…but that is not part of the variable's name,…more on that in just a second.…For example, to create a variable called X…and put the value five into it, that's all I have to do.…To create a variable called services,…and put a list of services in it,…that's all I have to do.…You can get pretty complicated with the pipeline…that appears on the right hand side of the equals.…
For example, we'll create a variable called…running services, so it will be equal to get service.…Then we're going to pipe that to where object…and only keep the ones…where the status is equal to running.…The way this works is everything on the right side…of the equal sign, runs as a single pipeline,…the results get assigned…to whatever's on the left side of the pipeline,…that's the variable.…Once it's in there, to see the contents of the variable…just access its name.…
And there's even a little bit of tab conclusion…
