这里列出了四种类型的变量。要在控制台中使用

cscript //nologo C:\pathto\script.vbs

请注意，有些变量没有列出，这些变量在set的帮助中列出-键入set /?。

Set WshShell = CreateObject("WScript.Shell")

Set wshsysEnv = WshShell.Environment("SYSTEM")
Wscript.echo "System"
For Each S In wshsysEnv
    WScript.echo S 
Next
Wscript.echo ""

Set wshsysEnv = WshShell.Environment("Volatile")
Wscript.echo "Volatile"
For Each S In wshsysEnv
    WScript.echo S 
Next
Wscript.echo ""

Set wshsysEnv = WshShell.Environment("User")
Wscript.echo "User"
For Each S In wshsysEnv
    WScript.echo S 
Next
Wscript.echo ""

Set wshsysEnv = WshShell.Environment("Process")
Wscript.echo "Process"
For Each S In wshsysEnv
    WScript.echo S 
Next
Wscript.echo ""

获取两个路径（在新安装的Windows上，用户路径为空，但软件可能会更改它）

Set wshsysEnv = WshShell.Environment("User")
Wscript.echo "User"
For Each S In wshsysEnv
    If lcase(left(S,5)) = LCase("PATH=") then WScript.echo S 
Next
Wscript.echo ""

Set wshsysEnv = WshShell.Environment("System")
Wscript.echo "System"
For Each S In wshsysEnv
    If lcase(left(S,5)) = LCase("PATH=") then WScript.echo S 
Next
Wscript.echo ""

要只获取开头不带“Path=”的系统路径，请使用以下命令

Set WshShell = CreateObject("WScript.Shell")

Set wshsysEnv = WshShell.Environment("System")
For Each S In wshsysEnv
    If lcase(left(S,5)) = LCase("PATH=") then WScript.echo right(S,Len(S)-5)
Next
Wscript.echo ""

你可以使用reg.exe来实现。只显示所有系统路径：

reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v path

当你想在一行显示每个路径时，这里有一个小批处理：

@echo off
setlocal
for /f "tokens=2* delims= " %%d in ('REG query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PATH 2^>nul') do (
  set "_REMAIN_=%%~e"
  call :Sub1
)
exit /b 0

:Sub1
for /f "tokens=1* delims=;" %%d in ("%_REMAIN_%") do (
  echo %%~d
  set "_REMAIN_=%%~e"
  if not "%%~e"=="" call :Sub1
)
exit /b 0

如果我们使用PowerShell，有一种方法。可以这样做。（欢迎更正，但这应该是相当准确的。）

**注意：**需要在管理员窗口使用。

1.将当前系统路径捕获到一个类似syspath的文件中。

powershell "[System.Environment]::GetEnvironmentVariable('PATH',[System.EnvironmentVariableTarget]::Machine)" >syspath

1.将系统路径放入变量中。

set /p v=<syspath

1.从当前syspath创建新路径。

set new_script_loc=C:\newscripts
set newpath="%new_script_loc%;%v%"
powershell "[System.Environment]::SetEnvironmentVariable('PATH','%newpath%',[System.EnvironmentVariableTarget]::Machine)"
