Powershell / Batch scripts do NOT run!

Please help me. I have written some powershell and batch scripts, yet when I run those files, they don't run. At most the powershell script just does step #1 but not all the other steps (lines of code / instructions). The batch script .bat file doesn't do anything. Both just pop up for like 2 seconds and then they disappear, Task Manager says nothing's being done.

 

PowerShell scripts not working with Call operator

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues while developing a PowerShell script using the Call operator. I would suggest you to refer the articles

The Windows PowerShell ISE.



However, as the issue is related to developing PowerShell scripts, I would suggest you to post your query on

MSDN forums, where we have expertise and developers who are well equipped with the knowledge of developing PowerShell scripts in Windows.

PowerShell does not launch bash.exe

All,

I
am new and trying to learn.

My
issue: When I enter bash.exe in a PowerShell cmd window, my PC does not launch the Ubuntu command. I think Windows Subsystem for Linux (WSL) is not in my $ENVath.

Troubleshooting
I have done:

1. Reading
   on the Internet, I can test my $ENVath by typing the following a PowerShell cmd:
   

PS C:\WINDOWS\system32>
where.exe calc

C:\Windows\System32\calc.exe

It returned the follow:

PS C:\WINDOWS\system32>
calc

(And the calculator displayed
on my PC)

1. Reading
   on the Internet, I can also test my $ENVath by typing the following a PowerShell cmd:
   

PS C:\WINDOWS\system32>
where.exe wsl

It returned the follow:

INFO: Could not find
files for the given pattern(s).

Here
is the output of $ENVath

PS
C:\WINDOWS\system32> $ENVath

C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\WINDOWS\System32\OpenSSH\;C:\Program
Files (x86)\Calibre2\;C:\Program Files\PuTTY\;C:\Program Files\Microsoft VS Code\bin;C:\Users\user-lenovo595\AppData\Local\Microsoft\WindowsApps

Question:

What
would you suggest as my next step to fix the issue?

Thank
you,
