親自寫過shell腳本後才發現,這玩意真是太方便了,當你想把一些瑣碎的、細節性的小指令一次性來完成時,腳本無疑是最好的選擇,方便、快捷,關鍵是真是懶人必備啊。
linux
因爲安裝的centos6.5是最小化安裝,且是實驗環境,即安裝在vmware workstations上面,在首次安裝完成後,配置完IP地址的相關信息後,就作了一個初始的快照,以便下次實驗完後,能夠經過快照快速還原系統。
shell
可是因爲實驗環境的要求,例如防火牆、SELinux、光盤掛載、yum源配置等,都是最常須要修改的選項,而且因爲最小化安裝,系統裏並無vim編譯工具和man手冊的查詢,因此致使每次還原快照後,還要處理這些瑣碎的問題。爲此,我就專門寫了這麼一個小腳本,內容並不複雜,可是也是一種學習過程,發出來和你們一塊兒分享一下,順便求指教......

另外,請不要吐槽個人英語。。。。雖然過了四級而且差點過了六級,然而仍是沒有什麼用。。。
