如何在Windows中使用Runtime.getRuntime().exec(command)?如何在Windows中使用Runtime.getRuntime()。exec(command)?
1.
command = "cat data.json"; // works in linux terminal
Runtime.getRuntime().exec(command) // runs in linux => Runs OK
2.
command = "type data.json"; // works in windows cmd
Runtime.getRuntime().exec(command) // runs in windows => Fails to run
3.
command = "cmd /C type data.json"; // works in windows cmd
Runtime.getRuntime().exec(command) // runs in windows => Runs OK
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream())); // Output is empty
在第三种情形,从input.readLine()的输出是空的,但如果我在cmd中使用命令式“data.json”,它会打印JSON它会在Linux上以同样的方式与“cat data.json”。我很困惑发生了什么事?我想在Windows和Linux上运行COMMAND。任何帮助表示赞赏!
谢谢!
