问题描述
我试图廉价并在Java中执行本地系统命令( uname -a
)。我希望从 uname
中获取输出并将其存储在String中。这样做的最佳方式是什么?当前代码:
I am attempting to be cheap and execute a local system command (uname -a
) in Java. I am looking to grab the output from uname
and store it in a String. What is the best way of doing this? Current code:
public class lame {
public static void main(String args[]) {
try {
Process p = Runtime.getRuntime().exec("uname -a");
p.waitFor();
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line=reader.readLine();
while (line != null) {
System.out.println(line);
line = reader.readLine();
}
}
catch(IOException e1) {}
catch(InterruptedException e2) {}
System.out.println("finished.");
}
}
推荐答案
您的方式离我可能做的不远:
Your way isn't far off from what I'd probably do:
Runtime r = Runtime.getRuntime();
Process p = r.exec("uname -a");
p.waitFor();
BufferedReader b = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = "";
while ((line = b.readLine()) != null) {
System.out.println(line);
}
b.close();
当然,处理您关心的任何例外情况。
Handle whichever exceptions you care to, of course.
