Shell指令碼組建目錄樹結構文字檔 -- Snippets

不管出於什麼目的, 本指令碼的作用組建目錄樹狀結構文字檔, 支援中文和有空格等的檔案目錄名. 比如
$./gdt.sh /cygdrive/e/ccccc -o
將/cygdrive/e/ccccc分類樹狀結構文字檔ccccc.txt. 如果不帶目錄名參數, 則產生目前的目錄樹狀結構.

本指令碼完成使用Bash編程, 並且未使用sed, awk等.

具體用法和選項含意可使用-h顯示簡單協助, 或見文章結尾原始碼:
$./gdt.sh -h

用法說明如下:
usage: gdt.sh [-h] [-o [file name]] [-n] [directory]
Generate directory tree.
|-- for file, /-- for empty directory, +-- for non-empty directory.

Options:
-h help page, any other options ignored
-o output results to a file, no file name follwed means output file has a name same as directory.
-n no screen output, if no file specificed, it redirects to /dev/null
All extra arguments will be ignored automatically.
Only the first directory will be considered if more exist.
