前几天在虚拟机上安装ubuntu7.0464bit时，遇到了一个经典的bug:failedtowritecache.由fc-cache-fv命令导致的。
google之后找到了两个解决的方法，觉得很有必要记录一下
方法之一，比较简单，写了一个很简单的脚本，然后执行下就可以了，内容如下：
#!/bin/bash
#
#修正Ubuntu7.04fc-cachefailedtowritecache错误

方法之二，很让我喜欢：
sudofc-cache-fv2>&1|grepfailed|cut-f1-d”:”|xargs-isudotouch{}&&sudofc-cache-fv
方法一比较的简单，当然也很实用
方法二充分利用了linux的命令，通过管道连接和一系列规则的运用，解决了问题。
相比较而言，我更喜欢第二个方法，shell真的很强大。最近就在翻一本学习bash的书，过段时间打算写几篇有关bash编程的日志，也算是自己学习的记录。
