java操作linux，调用shell命令

import org.junit.jupiter.api.Test;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.io.PrintWriter;

import java.util.logging.Level;

import java.util.logging.Logger;

public class Test001 {

    public static String exec(String command) throws InterruptedException {

        String returnString = "";

        Process pro = null;

        Runtime runTime = Runtime.getRuntime();

        if (runTime == null) {

            System.err.println("Create runtime false!");

        }

        try {

            pro = runTime.exec(command);

            BufferedReader input = new BufferedReader(new InputStreamReader(pro.getInputStream()));

            PrintWriter output = new PrintWriter(new OutputStreamWriter(pro.getOutputStream()));

            String line;

            while ((line = input.readLine()) != null) {

                returnString = returnString + line + "\n";

            }

            input.close();

            output.close();

            pro.destroy();

        } catch (IOException ex) {

            Logger.getLogger(Test001.class.getName()).log(Level.SEVERE, null, ex);

        }

        return returnString;

    }

    @Test

    public void test() throws Exception {

        System.out.println(exec("ls -al"));

    }

}

mac同样适用

调用shell脚本，判断是否正常执行，如果正常结束，Process的waitFor()方法返回0

public static void callShell(String shellString) {

    try {

        Process process = Runtime.getRuntime().exec(shellString);

        int exitValue = process.waitFor();

        if (0 != exitValue) {

            log.error("call shell failed. error code is :" + exitValue);

        }

    } catch (Throwable e) {

        log.error("call shell failed. " + e);

    }

}
