You can use a script block to specify different default values for a parameter under different conditions. PowerShell evaluates the script block and uses the result as the default parameter value. TheFormat-Table:AutoSizekey sets that switch parameter to a default value ofTrue. TheIfst...
Well, for starters, we used the–regexparameter instead of the –wildcard parameter; as you can probably guess, this tells the switch statement that we’re using regular expressions in our condition statements. In addition, we, well, use regular expressions in our condition statements. Suppose ...
