Question

I’m trying to use a command line implementation to change the PATH environment variable to remove a path, so I don’t have to manually remove it on a bunch of machines.

I have found this, which I can’t seem to get it to work:

%Path:str1=str2%

str1 is the path and str2 is null, which I’m not sure how to set it to null on the command line.

If there is another way, I would be glad to give it a try.

Using VBScript, you can get the path variable:

dim shell, env, path, path_entries
set shell = createobject("wscript.shell")
set env = shell.environment("system")
path = env("path")

Then split to get an array of the pieces:

path_entries = split(path, ";")

Set any entries to an empty string to remove them:

path_entries(3) = ""

Then reconstruct the path:

path = join(path_entries, ";") ' elements in path are delimited by ";"
env("path") = path
