大家好，我是延凱，本人原來在CSDN寫作已經快一年了 都是相關Linux運維這方面的技術知識，現在搬到博客園也是我一直想的，本博客主要寫Python，docker，shell等偏向開發雲計算等知識點，謝謝各位，聲明：（原先的CSDN也會不定時更新Linux運維等方面的知識！）

以上使用的過程都是一些if的判斷，這樣的練習能夠熟練掌握shell的if語句的作用，以及對if語句有一些清晰的了解，希望讀者能夠自己也去寫個shell腳本 尤其是剛接觸if語句的朋友麽，這樣才能夠提高自己的shell知識，同時也可以掌握shell之if語句的語法以及作用，如果完全可以看懂以上腳本的朋友麽 那麽恭喜你，你以及對if語句有一些認識了
再見！
