Question

我想在bash中做一些特别的事情。我找到了for循环和find的部分解决方案，但我更喜欢制作一个脚本来完成更复杂的工作。

我有一个复杂的目录结构如下：

fiction/
 book1/
  chapter1/
   page1.txt
   page2.txt
   ..
  chapter2/
   page5.txt
   page6.txt
  ..
 book2/
  chapter1/
  chapter2/
 ..
non-fiction/
 book5/
  chapter1/
..

我希望你明白这一点。

简而言之，我想做以下事情：

输入每本书和章节，例如第1章
在/mybooks/book1/chapter1.txt
进入下一章，并重复/mybooks/book1/chapter2.txt
继续阅读下一本书

我设法用简单的脚本做到了这一点：

for i in */; do cat "$i"*.txt > /newdir/"${i%%/}".txt; done

当我意识到书籍不仅在章节中，而且在包含章节的部分或子章节中都有分歧时，我的第一个问题出现了。唯一的解决方案是cd到这些文件夹并手动执行脚本。

但这不是专业方式。如何让脚本更智能地遍历子目录然后再返回？

Answer 1

您可以尝试以下方式：

for b in */*
do 
  cat $(find "$b" -type f -name \*.txt| sort) >> "$b"/$(basename "$b").txtb
done

Answer 2

这个答案......

处理带空格的目录
在页面

基于这些假设：

页面总是紧跟章节* </ li>
页面被命名为页面[一个或多个数字] .txt
只有一个部分与路径中的“chapter *”匹配，所以没有什么比“chapter2 / subchapter1”

#!/bin/bash

while read -r -d $'\0' path; do
    output="$path".txt
    ls -1 "$path"/page*.txt | \
     sed 's/^.*\([0-9][0-9]*\).txt/\1/' | \
     sort -n | \
     while read n; do
         echo "cat ${path}/page${n}.txt >> $output"
         # cat "${path}/page${n}.txt" >> "$output"
     done
done < <(find fiction/ -type d -name "chapter*" -print0)

如果对结果感到满意，请删除echo - 行并取消注释以下内容。
