i have following situation: a powershell script with this variables:
$RUBY = \"C:\\installing\\ruby\\bin\\ruby.exe\"
$ARGS = \"C:\\files\\sript.rb $Arg1 $Arg
First, $args
is an automatic variable managed by PowerShell, so I would avoid trying to declare your own variable with the same name.
To invoke a command stored in a variable from PowerShell, you can use the call operator &:
& $ruby 'script.rb'
If you need to build up the list of arguments, I would recommend creating an array, instead of mashing them all together into a single string:
$rubyArgs = @('C:\files\script.rb', $Arg1, $Arg2, $Arg3)
& $ruby $rubyArgs
If you need to pass more complicated arguments, you may find this answer useful.
