问题描述

I used "setx" to add a new path to my PATH environment variable. How do I see whether we can delete the newly added path from PATH environment variable?

推荐答案

从 %PATH% 中删除特定值需要您获取变量，修改它，然后将其放回.

Deleting a specific value from %PATH% needs you to get the variable, modify it, and put it back.

例如.

# Get it
$path = [System.Environment]::GetEnvironmentVariable(
    'PATH',
    'Machine'
)
# Remove unwanted elements
$path = ($path.Split(';') | Where-Object { $_ -ne 'ValueToRemove' }) -join ';'
# Set it
[System.Environment]::SetEnvironmentVariable(
    'PATH',
    $path,
    'Machine'
)
