linux配置文件比如".vimrc"里面的冒号有哪些相关资料?

cdd(){
clear
case "$1" in
"h" ) cd /media/15extended/home ;;
"d" ) cdd h; cdd dTa ;; #2011.08.26
"r" ) cdd h; cdd Txt/records ;;
* ) cd "$1" ;;
esac
ls
}

cdd r的实际运行結果是 clear -> cd 主文件夹 -> ls -> clear -> cd 记录文件夹 -> ls -> ls
最后重复了


anth@cn:~$ cdd r

看得有点头痛.函数重用?似乎这个定义有些混乱.
