写了一个显示目录树的脚本，可输出不对

LYOO · 发表于 2003-5-9 11:16:08

plan9客气了，指点谈不上，大家讨论一下吧:p
我读了你的脚本，我们的解题思路完全不同。
我的改造方案是：增加一个目录状态数组(每个组员可能有三种赋值1、2、3分别对应“|　”、“|－”、“　”)，由它来确定每行的目录树如何绘制，本行数组值在继承上一行数年组值的基础上，根据“本行文件是否为本层的最后一个目录”来确定是否对上行数组值的末位值进行修改。然后改造print_dash()，让它成根据数组数组值进行绘图。
这个方案的缺点就是改动比较大，但基本思路和你原脚本是一致的。

我的想法与你类似，而且我已经这样做了，不过我没有做数据组，这种方法实现起来速度非常慢，因为每进一个目录都要运行一次ls来找最后一个文件。
而且我现在还有一个问题没有解决，你看一下我的脚本的输出就知道了。

这里：

实际应该为：

| | |-- 123
| | |-- 1234
| | `-- 12346

| |-- tree
| `-- tree.sh

复制代码

那就实现了我想像的功能了。

呵呵，你现在遇到的问题，也是我写该脚本时遇过的最大问题。不过既然你已经确定本层最后一个文件是否为目录，这个问题基本上已解决了（跟据这个判断对下层做相关处理就过关了）。;)

但是碰到一个奇怪的问题，在while对FILECOUNT和DIRCOUNT作的改动，并没有改变全局变量FILECOUNT和DIRCOUNT。

LSPROG -1 "$1" | while read f

但是碰到一个奇怪的问题，在while对FILECOUNT和DIRCOUNT作的改动，并没有改变全局变量FILECOUNT和DIRCOUNT。

这是因为你使用管道造成shell新开一个子进程来运行while...，所以while里面的变量就变成了局部的，你可以使用export将其导出到父进程中。

同时，我做了一点修改，现在可以显示空格文件了，感谢guangold发现这个问题。
