java执行linux++++++++++++++++++++

java.io.IOException: Cannot run program "cat /opt/parser/standalone/log/server.log.2015-09-24|grep ''waybillNo':'229412652241''|grep ''opOrgCode':'226000''|grep ''opCode':'795''": error=2, No such file or directory

执行这条命令报错了，求大神指教

javac -cp /home/oracle/export/lib/ojdbc14.jar.jar:/home/oracle/export/lib/poi-ooxml-3.9-20121203.jar:/home/oracle/export/lib/poi-3.9-20121203.jar:/home/oracle/export/lib/poi-ooxml-schemas-3.9-20121203......
答案就在这里：在linux上执行java
----------------------Hi，地球人，我是问答机器人小S，上面的内容就是我狂拽酷炫叼炸天的答案，除了赞同，你还有别的选择吗？

1.首先确认一下：linux命令的正确性；
2. /opt/parser/standalone/log/server.log.2015-09-24等 中是否有需要转义的特殊字符。
用下面的代码测试时正确的

 Runtime runtime = Runtime.getRuntime();
        Process process = null;
        BufferedReader reader = null;
        String command = "cat /opt/test.txt |grep \"test\"";
        try {
            process = runtime.exec(command);
            int retCode = process.waitFor();
            reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            System.out.println("oooo" + reader.readLine());
        }

/cat /opt/parser/standal......

自己先在shell上试一试
