Question

我正在通过Shell脚本运行一个命令，因此无论Shell脚本提供的数据如何，我都需要以Java代码打印。要实现这一点，我要通过Java在Shell脚本下执行。但是，从shell脚本获取的 $ data 都是以Java打印的。谁能帮我吗？

下面是我的adb.sh

#!/bin/sh

REPO_DIR=/home/jagadeesh/android-sdk-linux/platform-tools/
cd ${REPO_DIR}
data= adb shell logcat | grep testing_aws
echo $data

下面是我的Java文件：这里我正在执行Shell脚本

String[] cmdScript = new String[]{"/bin/bash", "-C", "/home/jagadeesh/Desktop/automation/Adb_logs/adb.sh"}; 

StringBuilder output2 = new StringBuilder();

try {
    Process procScript = Runtime.getRuntime().exec(cmdScript);

    procScript.waitFor();
    BufferedReader reader = 
        new BufferedReader(new InputStreamReader(procScript.getInputStream()));

    // System.out.println(reader);
    String line = "";
    while ((line = reader.readLine())!= null) {

        output2.append(line + "\n");
        System.out.println(output2);
    }
} catch (Exception e) {
    e.printStackTrace();
}

在abd.sh中将data= adb shell logcat | grep testing_aws更改为

data=`adb shell logcat | grep testing_aws`

请找到对我有用的代码

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Script {

        public static void main(String[] args) {
                // TODO Auto-generated method stub
                String cmdScript = "/home/abd.sh";

                StringBuilder output2 = new StringBuilder();

                try {
                    Process procScript =  Runtime.getRuntime().exec(cmdScript);
                    procScript.waitFor();
                    BufferedReader reader =
                        new BufferedReader(new InputStreamReader(procScript.getInputStream()));
                    // System.out.println(reader);
                    String line = "";
                    while ((line = reader.readLine())!= null) {

                        output2.append(line + "\n");
                        System.out.println(output2);
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }

        }

}

abd.sh

#!/bin/sh

data=`cat /home/new.ldif|grep dn`
echo $data

输出

bash-3.00$ java Script

dn: dc=opensso,dc=java,dc=net

无法将外壳程序脚本的输出输出到Java代码
