Java调用shell脚本的一些问题

代码:

public class JavaAndShell {
    public static void main(String[] args) {
        InputStreamReader stdISR = null;
        InputStreamReader errISR = null;
        Process process = null;
        String command= "bash /home/hadoop/test.sh";   //程序路径
        
        try {
            process = Runtime.getRuntime().exec(command);
            try {
                int exitValue = process.waitFor();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            String line = null;

            stdISR = new InputStreamReader(process.getInputStream());
            BufferedReader stdBR = new BufferedReader(stdISR);
            while ((line = stdBR.readLine()) != null) {
                System.out.println("STD line:" + line);
            }

            errISR = new InputStreamReader(process.getErrorStream());
            BufferedReader errBR = new BufferedReader(errISR);
            while ((line = errBR.readLine()) != null) {
                System.out.println("ERR line:" + line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (stdISR != null) {
                    stdISR.close();
                }
                if (errISR != null) {
                    errISR.close();
                }
                if (process != null) {
                    process.destroy();
                }
            } catch (IOException e) {
                System.out.println("正式执行命令:" + command + "有IO异常");
            }
        }
    }
}

在IDEA中打成jar包,然后上传到Linux中

注意:上传后需要修改文件权限:chmod a+x xxx.jar

            运行jar包,命令 java -cp xxx.jar 包名.类名
