conditions when getting parameters

I have the parameters as followed

[CmdletBinding()]



param

(



[

Parameter(Mandatory=$True,Position=1)]

[

String]$src,

[

Parameter(Mandatory=$True,Position=2)]

[

String]$destsite,

[

Parameter(Mandatory=$True,Position=3)]

[

String]$destlib,

[

Parameter(Mandatory=$True,Position=4)]

[

String]$exclusions,

[

Parameter(Mandatory=$True,Position=5)]

[

String]$permissionmap,

[

Parameter(Mandatory=$False,Position=6)]

[

String]$batch,

[

Parameter(Mandatory=$True,Position=7)]

[

Int]$quota,

[

Parameter(Mandatory=$False,Position=8)]

[

Switch]$dryrun,

[

Parameter(Mandatory=$False,Position=9)]

[

Switch]$copy


)

What I am wanting to do is, if batch is there src, destsite and destlib are no longer necessary

also if any of the parameters are spelt wrong like -cpy then I can put my own error message in

Please don't post colorized text from IDE as it is impossible to read in most browsers.

I have reformatted your code for readability

[CmdletBinding()]
param
(
  [Parameter(Mandatory=$True, Position=1)] [String] $src,
  [Parameter(Mandatory=$True, Position=2)] [String] $destsite,
  [Parameter(Mandatory=$True, Position=3)] [String] $destlib,
  [Parameter(Mandatory=$True, Position=4)] [String] $exclusions,
  [Parameter(Mandatory=$True, Position=5)] [String] $permissionmap,
  [Parameter(Mandatory=$False,Position=6)] [String] $batch,
  [Parameter(Mandatory=$True, Position=7)] [Int]    $quota,
  [Parameter(Mandatory=$False,Position=8)] [Switch] $dryrun,
  [Parameter(Mandatory=$False,Position=9)] [Switch] $copy
)

Your question is still too vague.  Can you read what you asked and write it in complete sentences.  Maybe you typo-ed some of it.

I wonder if that was a sufficient answer for the OP ?

The one issue that was asked that I don't relate to ParameterSets is the discovery of misspelled parameters and the way to code a specialized diagnostic when they are discovered.
