输入子目录(带空格)并将文件合并到另一个目录

Question

我想在bash中做一些特别的事情。我已经找到了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/
..

我希望你能明白。

简而言之，我想做以下事情：

1. 输入每本书和每一章，例如第1章
2. 将第1页、第2页等全部放入/mybooks/book1/chapter.txt
3. 继续下一章，对/mybooks/book1/chapter2.txt重复
4. 继续读下一本书

我用一个简单的脚本做到了这一点：

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

当我意识到有些书不仅分为章节，而且分为包含章节的部分或小节时，我的第一个问题就出现了。唯一的解决方案是cd到这些文件夹并手动执行脚本。

但这不是专业的方式。如何使脚本更智能地遍历子目录，然后再移回？

Answer 1

您可以尝试以下操作：

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

Answer 2

这个答案。。。

• 处理带有空格的目录
• 如果一章中有超过9页，则对页面进行正确排序

---

它基于以下假设：

• 页面总是紧挨着第章*
• 页面被命名为page[一个或多个数字].txt
• 路径中只有一个部分与"chapter*"匹配，所以没有什么比得上"chapter2/succapter1"

---

#!/bin/bash
while read -r -d $'' path; do
    output="$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)

如果对结果满意，请删除echo-行并取消对下面一行的注释。

示例：

find f
f
f/book2
f/book2/chapter1
f/book2/chapter1/page10.txt
f/book2/chapter1/page2.txt
f/book2/chapter1/page1.txt
f/book2/chapter3
f/book2/chapter3/page2.txt
f/book2/chapter3/page1.txt
f/book2/chapter2
f/book2/chapter2/page2.txt
f/book2/chapter2/page1.txt
f/book2/part1
f/book2/part1/subsection1
f/book2/part1/subsection1/chapter1
f/book2/part1/subsection1/chapter1/page2.txt
f/book2/part1/subsection1/chapter1/page3.txt
f/book2/part1/subsection1/chapter1/page1.txt
f/book1
f/book1/chapter1
f/book1/chapter1/page2.txt
f/book1/chapter1/page1.txt
f/book1/chapter3
f/book1/chapter3/page2.txt
f/book1/chapter3/page1.txt
f/book1/chapter2
f/book1/chapter2/page2.txt
f/book1/chapter2/page1.txt
f/book with space
f/book with space/chapter1
f/book with space/chapter1/page2.txt
f/book with space/chapter1/page1.txt

输出：

cat f/book2/chapter1/page1.txt >> f/book2/chapter1.txt
cat f/book2/chapter1/page2.txt >> f/book2/chapter1.txt
cat f/book2/chapter1/page10.txt >> f/book2/chapter1.txt
cat f/book2/chapter3/page1.txt >> f/book2/chapter3.txt
cat f/book2/chapter3/page2.txt >> f/book2/chapter3.txt

cat f/book2/chapter2/page2.txt >> f/book2/chapter2.txt

cat f/book2/part1/subsection1/chapter1/page2.txt >> f/book2/part1/subsection1/chapter1.txt
cat f/book2/part1/subsection1/chapter1/page3.txt >> f/book2/part1/subsection1/chapter1.txt
cat f/book1/chapter1/page1.txt >> f/book1/chapter1.txt
cat f/book1/chapter1/page2.txt >> f/book1/chapter1.txt
cat f/book1/chapter3/page1.txt >> f/book1/chapter3.txt
cat f/book1/chapter3/page2.txt >> f/book1/chapter3.txt
cat f/book1/chapter2/page1.txt >> f/book1/chapter2.txt
cat f/book1/chapter2/page2.txt >> f/book1/chapter2.txt
cat f/book with space/chapter1/page1.txt >> f/book with space/chapter1.txt
cat f/book with space/chapter1/page2.txt >> f/book with space/chapter1.txt
