Examples

• 從 SYSTEM 環境變數加入一個 PATH 路徑 (加在路徑最前面，優先權最高)

  setenv -ap PATH %%C:\AngularDev\Code\bin

  寫在 *.bat 中要將 % 寫成 %% 才行

• 從 USER 環境變數加入一個 PATH 路徑 (加在路徑最前面，優先權最高)

  setenv -uap PATH %%C:\AngularDev\Code\bin

  寫在 *.bat 中要將 % 寫成 %% 才行

• 從 SYSTEM 環境變數刪除一個 PATH 路徑

  setenv -d PATH %%C:\AngularDev\Code\bin

  寫在 *.bat 中要將 % 寫成 %% 才行

• 從 USER 環境變數刪除一個 PATH 路徑

  setenv -ud PATH %%C:\AngularDev\Code\bin

  寫在 *.bat 中要將 % 寫成 %% 才行
