How can I invoke a powershell script from within another script? This is not working:
$param1 = "C:/Users/My Folder/file1"
$param2 = "C:/Users/My Folder/file2"
$command = "C:/Users/My Folder/second.ps1"
Invoke-expression $command -File1 $param1 -File2 $param2
... Second.ps1:
param(
[string]File1, [string]File2)...
If there are no spaces:
Invoke-expression "$command $param1 $param2"
If you know where the spaces are:
Invoke-expression "$command `$param1HasSpaces` $param2"
NB: If your execution policy is restricted (check with get-executionpolicy use:
Invoke-Expression "powershell -executionpolicy bypass -command `"$command $param1 $param2`""
You can do it like this if you slightly change your approach. Basically create the command string you want to execute, then create a scriptblock object from that and then use Invoke-Command instead of Invoke-Expression.
$param1 = "C:/Users/My Folder/file1"
$param2 = "C:/Users/My Folder/file2"
$command = "C:/Users/My Folder/second.ps1"
$str = '{0} -File1 "{1}" -File2 "{2}"' -f ($command, $param1, $param2)
$sb = [scriptblock]::Create($str)
Invoke-Command -ScriptBlock $sb
& $command -File1 $param1 -File2 $param2
