Posted 2020-11-05 追极

1.脚本test.sh,置于/Users/hdwang目录下

#!/bin/sh

cd /Users/hdwang
echo ls:`ls`

for((i=1;i<=10;i++));
do
echo $(expr $i \* 3 + 1);
sleep 1s
done

echo jps:`jps -l`

2.java执行test.sh

public class ExecShell {

    public static void main(String[] args) {

        try {
            Process pro = Runtime.getRuntime().exec("/Users/hdwang/test.sh");
            InputStream in = pro.getInputStream();
            BufferedReader read = new BufferedReader(new InputStreamReader(in));
            String line = null;
            while((line = read.readLine())!=null){
                System.out.println(line);
            }

            pro.waitFor();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
