Linux从Java查找命令不起作用

Question

Can anyone help me get this code working in linux

    public static void main(String[] args) throws Exception,{   
    String s ="find . -exec ls -al {} \\;";
    Process exec = Runtime
            .getRuntime()
            .exec(s);
    exec.waitFor();
System.out.println(s);
    if (exec.getErrorStream().available() != 0) {
        BufferedInputStream bf = new BufferedInputStream(
                exec.getErrorStream());
        DataInputStream din = new DataInputStream(bf);
        System.out.println(din.readLine());
    }

    System.out.println(exec.exitValue());
}

I am getting the following output.

find . -exec ls -al {} \;
find: missing argument to `-exec'

Answer 1

Try using this:

String[] params = {"find", ".", "-exec", "ls", "-al", "{}", ";"};

instead of your plain String command.

Be careful though: The output is heavy (I tested with /dev/.) and the waitFor method may cause your I/O Buffer to burst.

Answer 2

反斜杠太多

find . -exec ls -al {} ';'
