awk url

用grep 的时候可能很慢，是因为使用了utf-8系统环境语言变量，换成C或者en_US就好了，在gzip的使用也可能会遇到类似问题~

linux系统下的多文件替换

又是一个老问题，不过对刚刚接触Unix/Linux的人来说还是非常管用的
find . -name "*.c" | xargs sed -i 's/xxx/yyy/g'

以安全的方式更改文件中的大小写
$cat toc.html | tr '[:upper:]' '[:lower:]' > toc1.html
$mv toc1.html toc.html

使用awk的RS变量，一次显示出ini的一个段

记得有个取多行的参数。原来是RS。岂不是方便得很。
$ awk -F[ 'BEGIN{RS = ""} /Fonts]/' ~/.opera/opera6.ini
