为什么会重复显示

[anth]

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


----------------------
回3楼，也不行，还是重复，看来递归调用自身这个函数只是看起来简单，我绝望了，改回去了

cdd(){
if [ "$1" = "h" ]; then cd /media/15extended/home; fi
if [ "$1" = "d" ]; then cd /media/15extended/home/dTa; fi
if [ "$1" = "r" ]; then cd /media/15extended/home/Txt/records; fi
cd "$1" 2>/dev/null
clear
ls
}

看得有点头痛.函数重用?似乎这个定义有些混乱.

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

代码： 全选

Associative arrays are created using declare -A name.

代码： 全选

declare -A directories
directories[h]=...
directories[r]=...
...
ccdd ()
{
    if [ "${directories[$1]}" ] ; then
        cd "${directories[$1]}"
    else
        cd "$1"
    fi
    ls
}

谢谢，这个方法好用，我格了硬盘后只改了directories[h]就一切正常了
