Cmdlet and parameter sets

[Patrick Dreyer]

Hi,

I'm struggling getting a cmdlet with parameter sets working.
I'd like to support three different "flavors" for calling my cmdlet Run-SSHCmd:
1) run-sshcmd Command (Parameter set "SharedConnecti on")
2) run-sshcmd Command SuPassword (Parameter set "SharedConnecti onSu")
3) run-sshcmd Command SuUser SuPassword (Parameter set "SharedConnecti onSuUser")

1) "run-sshcmd ls" -ok, ParameterSetNam e = "SharedConnecti on"
2) "run-sshcmd ls test" -ERROR, requests SuPassword
3) "run-sshcmd ls root test" -ok, ParameterSetNam e = "SharedConnecti onSuUser"

According to the output (see below) of my PowerShell script parameters.ps1 (see below), the implementation (see below) is correct.

Any suggestions?

Just did so. Thank you for the hint.
