I'm sorry! I'm a newbie! I plan to create a batch file. It needs to add J:\Lotus\Notes\Data to the current PATH. Is there any senior brother to help?

Hey, in Java teaching, there are always people who mess up the path system variable, which causes many program loading problems. But after looking at setx for a long time, I find that it only has the replace function and no append function, which makes it a bit troublesome.

I'm also working on this problem and want to try setx. I've modified the environment variables with wimc but they can't take effect immediately.

Modifying environment variables with wmic can take effect immediately. Did you write the command incorrectly? Post it and let's see?

1. Use pathman
pathman /rs "c:\123"
pathman /as "C:\WINDOWS\system32\qqq"
pathman /as J:\Lotus\Notes\Data
2. Use WMIC
WMIC /PRIVILEGES:ENABLE ENVIRONMENT where name='PATH' set VariableValue="%PATH%;J:\Lotus\Notes\Data"
pathman /rs "c:\123"
pathman /as "C:\WINDOWS\system32\qqq"
pathman /as J:\Lotus\Notes\Data
2. Use WMIC
WMIC /PRIVILEGES:ENABLE ENVIRONMENT where name='PATH' set VariableValue="%PATH%;J:\Lotus\Notes\Data"

I used to use reg add/delete to modify the registry (in bat scripts) to add or delete environment variables before, but I found that after adding them, they don't take effect immediately and I need to restart the OS. I wonder if there is a way without restarting the OS.

```
wmic ENVIRONMENT where "name='path' and username='<system>'" set VariableValue="%path%;C:\test"
```
wmic ENVIRONMENT where "name='path' and username='<system>'" set VariableValue="%path%;C:\test"

You can use the command-line tool NirCmd to refresh the environment variables:
NirCmd sysrefresh environment
Or use a tool to modify environment variables, such as pathman
