Linux ——記一記那恐怖的 rm -f

　　今天想試試iscsi構建的FTP，本來想用單機的虛擬機器，結果發現有諸多問題，只能依賴兩台Redhat6了，結果在給第二台配置yum的時候，最悲劇、最悲慘、最壯烈的一幕發生了~~~~

　　安裝好yum（yum的安裝依賴包還真有點多）後，在 /etc/yum.repos.d/  目錄中存在三個檔案。想想單機無需使用外部的yum源，所以這三個檔案就不要了——刪之~~~

在這裡，我把我的操作過程貼出來：

　　一看到出現“rm: cannot remove `abrt': Is a directory”就呆了~~~~

　　看看那etc目錄就剩幾個乾巴巴的檔案夾了，如果要是用   rm -rf *,剩下的就只有那麼一個空空的etc了~~

　　在網上找了找解決辦法，大致也就是資料恢複。一向謹慎的我，居然犯這麼低級的錯誤——應該是昨晚洗頭的原因吧~~

　　預防措施：

　　1、良好的變更檔的策略：變更檔時先進行備份操作——建立一個bak檔案甚至建立一個bak檔案夾

　　2、刪除的檔案最好能放在一個臨時的隱藏檔夾中，最好找一種類似於清除的程式，並定時清理

　　3、不能輕易使用  rm -fr 等命令  ——  三思而後行也~~
