你怎麼樣知道路由器運行了多長時間？

       今天下午去太平洋電信。初進入公司映像不錯，很靠譜的感受，保安給人的感受都那麼專業。牆上掛着一面宣傳畫，上面滿滿的全是簽名。讓我奇怪的是怎麼這麼多日本名字，大週二？大田二？後來才知道這是日本的合資企業，suo ga！

      技術面在一件會議室進行。聊了大概一個小時吧，問的仍是挺細的，主要是運營商方面的技術。有一個小問題卻把我難住了：你怎麼知道路由器運行了多長時間？

      我想了想，難道是show process cpu 或者show memmory ？好像沒有這個信息啊？

      我只好老老實實說這個真不知道。

      回來上百度一查，原來是show version 啊！這個命令我在搞安全的時候常常用的，爲了看PIX打開了那些功能，卻歷來沒有關注過它在哪裏給出了系統運行的時間！在路由器跑了一下，還真有！

        爲何會一直沒有注意，其實不光是本身不夠用心的緣由，還有本身的英語不夠利落的緣由。若是你把英語說的跟本身的母語同樣麻溜，看英語書跟看漫畫同樣輕鬆，這句話你就早看見了！

         學好英語！必定要學好英語！

        哦，技術面獲得了確定，下面就等這人事的面試了。

        加油，吼吼！
