PowerShell - 如何对特定文件执行 BAT（批处理）命令？ （连接路径和命令并传播 arguments ）

Question

I need to execute in PowerShell 5 some robot (RobotFramework) batch file on specific robot file. Simple usage by documentation is: "robot file.robot" which works but in the PowerShell script I am having issues. I defined:

$ROBOT_PATH="C:\Program Files\Robot\Scripts"

But when trying to execute:

$ROBOT_PATH\robot.bat User.robot

Getting an Error: Unexpected token '\robot.bat' in expression or statement.

If I try: "$ROBOT_PATH\robot.bat" User.robot or "$ROBOT_PATH\robot.bat" "User.robot" then getting: Unexpected token '"User.robot"' in expression or statement.

So how to concatenate Path and Command and propagate Arguments for that command? Important thing to emphasize is that I should not first do the " cd to PATH" before executing the command. If I do the "cd" then it works!

Answer 1

You need to put the path to a string like this

& "${ROBOT_PATH}\robot.bat" User.robot

To re-enable the variable substitution you have to use the curly brackets.
