linux服务器中的项目读取linux文件

import java.io.IOException;
import java.io.InputStreamReader;
import java.io.LineNumberReader;
import java.util.ArrayList;
import java.util.List;

public class RunTimeUtil {
    private static LogUtil logger = new LogUtil(RunTimeUtil.class);

    public static List<String> execCom(String cmd) throws IOException, InterruptedException {
        List<String> msgList=new ArrayList<String>();
        try {
            Process process = Runtime.getRuntime().exec(new String[]{"/bin/sh", "-c", cmd});//执行命令

            InputStreamReader ir = new InputStreamReader(process.getInputStream());
            LineNumberReader input = new LineNumberReader(ir);

            String line;
            while ((line = input.readLine()) != null) {//输出结果
                msgList.add(line);
            }
        } catch (java.io.IOException e) {
            logger.info("IOException " + e.getMessage());//捕捉异常
        }
        return msgList;
    }
}

然后调取execCom(“所需命令”);
