標題: How to use “cd” command using Java runtime on Linux?
當用下面敘述時會錯誤

1. String[] command = new String[]{"cd",path};
   
2. Process child = Runtime.getRuntime().exec(command, null);

複製代碼

可改用

1. String[] cmd = { "/bin/sh", "-c", "cd /var; ls -l" };
   
2. 
   
3. Process p = Runtime.getRuntime().exec(cmd);

複製代碼

這樣就可以了

或

1. String cmd = "cd /var; ls -l";
   
2. 
   
3. Process p = Runtime.getRuntime().exec(new String{"/bin/sh","-c",cmd });

複製代碼
