这是一个正在进行的工作，我正在寻找更多知识的人的build议（电脑是我的爱好，而不是我的专业）。
这个脚本是为了组织一个电视节目目录（把每个文件重命名为Ep1ode.ext的惯例S01E01.Title，并创build一个原始名称的符号链接）。
我喜欢写这篇文章，我不希望别人花太多时间。 我想现在我最大的“走狗”是：
用wiki中的awk抓取正确的文本块（根据季节＃）
（如果有什么看起来效率低下，请让我知道 – 我正在学习）
我一直在左右这些论坛上，随着我的进展而取得进展。 我已经用尽了大部分类似的问题。 （这些论坛是我build立这个目标的100％）。
## Find show name and season (directories nested: /show/season) show1=$(cd .. ; pwd) show="${show1##*/}" season=("${PWD##*/}") IFS=$'\n' ## Download list of episodes for given season wget -q -O- --header\="Accept-Encoding: gzip" https://en.wikipedia.org/wiki/List_of_$show\_episodes | gunzip > tmp.html ## Working on first awk/sed command to grab textblock of only specific season ## grep command works great, except when episode is hyperlinked ('a href' tag gets cut) if [ "$season" == 'Season 1' ]; then listing=( $(awk '/\(season_1\)/,/rellink/' tmp.html | grep "summary.*[\"]<" | cut -d'"' -f6) ) unset IFS elif [ "$season" == 'Season 2' ]; then listing=( $(awk '/\(season_2\)/,/rellink/' tmp.html | grep "summary.*[\"]<" | cut -d'"' -f6) ) unset IFS #..........................continued 20 times or so fi 我已经对上面的代码进行了很多的调整，所以下半年就要完成了。 但之前它已经工作了90％。 唯一的问题是，如果它们在维基百科页面上超链接（因为剪切），它将命名一些文件S01E05.ahref = .mkv 。
## Parse filename for season/episode descriptor ## Rename file with season/episode and name from wikipedia database for file in * do name=$(ls "$file" | grep -o "S[0-9][0-9]E[0-9][0-9]") episode=$(ls "$file" | grep -o "E[0-9][0-9]") if [ "$episode" == 'E01' ]; then mv "$file" "$name.${listing[0]}.mkv" ln -s "$name.${listing[0]}.mkv" "$file" echo "Renamed '$file' and created a symbolic link." #..........................continued fi done
同意这些意见， bash不是解析网页或html时要走的路。 但是，如果你已经开始，并想在bash中做到这一点，那么这不是不可能的。 看看你的代码，我喜欢你使用bash替换和globing，但是如何把它们放在一起，有点困惑，所以写了一个我自己的简单版本，你可以插入或删除它。
#!/bin/bash show="Archer" url="http://en.wikipedia.org/wiki/List_of_${show}_episodes" while read line; do [[ $line =~ "<h3><span class=\"mw-headline\" id=\"Season" ]] && episode= && (( if [[ $line =~ "<td class=\"summary\" style=\"text-align: left;\">\""(.*)"\"" title="${BASH_REMATCH[1]}" [[ "$title" =~ "title=\""(.*)"\"" ]] && title="${BASH_REMATCH[1]}" title="${title%%\"*}" title="$(echo ${title/($show)/})" echo "Season [$season] Episode [$((episode+=1))] Title [$title]" fi done < <(wget -qO- "$url")
输出示例:(也用scrubs和simpsons测试得到正确的结果）

说明 ：
我发现BASH_REMATCH在很多情况下很有用，比如你必须匹配子字符串，而不想找出一些疯狂的正则表达式。
BASH_REMATCH An array variable whose members are assigned by the =~ binary operator to the [[ conditional command. The element with index 0 is the portion of the string matching the entire regular expression. The element with index n is the portion of the string matching the nth parenthesized subexpression. This variable is read-only.
否则，主要问题如您所述，标题格式可能会有所不同。 所以我只是做了另外一个BASH_REMATCH ，当它是一个href的时候（当它有一个title属性的时候），并且在情节还没出来的时候删除了奇数情况下的尾随文本。 也许还有一些其他的情况，但是这对我测试过的所有3个节目都有效。
让我建议一个多平台的网络抓取CLI ，似乎没有得到足够的关注： xidel
它支持Xpath 2，CSS 3，XQuery 1，JSONiq查询语言。
与手头场景的简化版本一起使用，我们得到以下内容，希望能够让您了解更轻松的抓取变得如何：
#!/usr/bin/env bash # Example values. show='Archer' season=2 # Synthesize the URL to scrape. url="http://en.wikipedia.org/wiki/List_of_${show}_episodes" # The XPath expression for extracting the specified season's episode titles qryEpisodeTitles="//*[matches(@id, '^Season_$season')] /../following-sibling::table[1]//td[@class='summary']" # Scrape the page at the URL and read all episode titles # (including enclosing " chars.) into an array. IFS=$'\n' read -d '' -ra episodeTitles <<<"$(xidel -e "$qryEpisodeTitles" "$url")" # Enumerate all episode titles with an index. # Note: Typically, episodes are enclosed in literal `"` chars.; additionally, # after the closing `"`, they may contain footnote references, such as # `[2]` or `†`, so some cleaning-up may be required. i=0 for episodeTitle in "${episodeTitles[@]}"; do echo "Episode $((++i)): $episodeTitle" done
感谢BroSlow的帮助（和代码！）脚本是完整的。
