I want to make a argument Mandatory based on the Switch Condition Something Like
param(
[string]$para1,
[switch]$choice="Upgrade"
[string]$paraUpg
[string]$paraInstall
)
now if the choice is Upgrade I want to make $paraUpg mandatory and if $choice is Install then $paraInstall has to be mandatory
You could try something like the following. Setup all of your parameters and if $choice="Upgrade" and $paraUpg is null or empty throw an exception. Repeat similarly for $choice="Install". You could then conditionally choose what to do after the parameter check based on the parameters chosen.
param(
[string]$para1,
[string]$choice="Upgrade",
[string]$paraUpg,
[string]$paraInstall
)
#check if choice is "Upgrade" and paraUpg is empty
if(($choice -eq "Upgrade") -and ([string]::IsNullOrEmpty($paraUpg)))
{
throw "paraUpg is a required parameter"
}
#check if choice is "Install" and paraInstall is empty
elseif (($choice -eq "Install") -and ([string]::IsNullOrEmpty($paraInstall)) )
{
throw "paraInstall is a required parameter"
}
first of all its PowerShell which comes along with windows 7 as one of its added utilities.
you have not given any detail about what have you done so far. I suspect you want something like this.
in your PowerShell script declare params preferably at top.
param([string]$UserName, [string]$Password, [string]$MachineName)
use these parmas within your powershell script wherever required. Now create a batch file from where you can pass values to these params like this.
@powershell -ExecutionPolicy Unrestricted -FILE YourPowerShellScript.ps1 "UserName" "Password" "MachineName"
i have specified Policy rights within batch file so you don't have to mention each time when you run the script on different machines. Hope it helps.
ExecutionPolicy rights to Unrestricted within argument batch file which will handle your case. you can either set it to Set-ExecutionPolicy AllSigned.
