如何在Powershell中和内部调用函数？

Question

Suppose I have a function in test.ps1, its name is show the code is like below:

. "some_path\some_other_script.ps1"

function show {
    write-host "Hello World"
    #some other function call from some_other_script.ps1
    ...
}

How can I call show in follow format (in a & - call operator)

powershell.exe "& '%test_script_path%\test.ps1'\show"

I think I need to dot source test.ps1 first in order to get dependencies in show function from some_other_script.ps1

I know I can create a new script and put the code in show in the new script instead of in a function. In that way, when do &... the script will be invoked. But I don't want to create a new script just for a very simple function

Thanks for any suggestion

Answer 1

You could dot source it and then call it like this.

powershell -Command ". '%test_script_path%\toolsql.ps1'; show"

The ; is used as a separator between commands.

Answer 2

I am really appreciated for the help and time from @Patrick Meinecke, the following command works.

powershell -command ". .\test.ps1;show"

Like he mentioned in the chat, "So to explain that the .\\ just indicates it's in the current directory it still needed the other . to tell powershell to load the script into the current context"
