Script Parameter Alias

i modified 1 of scripts adding new switch parameter, gave parameter alias of "db", when run script .\myscript.ps1 -db following error

parameter alias cannot specified because alias name 'db' defined multiple times command.
@ line:1 char:1
+ .\myscript.ps1 -db
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + categoryinfo          : metadataerror: (:) [], metadataexception
    + fullyqualifiederrorid : aliasparameternamealreadyexistsforcommand

in script not have other aliases called "db", there 1 called "d", , if get-alias, there alias of "dbp". why can not use alias of "db"?

hi clayman,

i figured out (i think):
"db" reserved parameter alias, used -debug parameter. without cmdletbinding, powershell not abide use.

btw, there no point in assigning default values switches - $false if not set. there no meaning in validatepattern $wonumber (it's numeric type already. use validaterange limit specific number range).

cheers,
fred
