shell脚本查找，搜索和文件替换字符串数组 [英] Shell script to find, search and replace array of strings in a file

问题描述

这是链接到另外一个问题/ code高尔夫我问的<一个href=\"http://stackoverflow.com/questions/3171552/$c$c-golf-color-highlighting-of-repeated-text\">http://stackoverflow.com/questions/3171552/$c$c-golf-color-highlighting-of-repeated-text

我有一个包含以下内容的文件'sample1.txt'：

<$p$p><$c$c>LoremIpsumissimplydummytextoftheprintingandtypesettingindustry.LoremIpsumhasbeentheindustry'sstandarddummytexteversincethe1500s,whenanunknownprintertookagalleyoftypeandscrambledittomakeatypespecimenbook.

我有一个脚本生成的字符串下面的数组中发生文件（只有少数出于说明）中：

  LoremIpsum
LoremIpsu
dummytext
oremIpsum
LoremIps
dummytex
行业
oremIpsu
remIpsum
ummytext
LoremIp
dummyte
emIpsum
INDUSTR
mmytext
 

我需要（从顶部）看是否LoremIpsum'在文件sample1.txt发生。如果是这样，我想，以取代LoremIpsum出现的所有：＆LT; T1＆GT; LoremIpsum＆LT; / T1＆GT; 。现在，该程序移动到下一个单词LoremIpsu的时候，它不应该匹配的＆LT; T1＆GT; LoremIpsum＆LT; / T1＆GT;内sample1.txt 文本。它应该重复上述这个数组的所有元素。下一个有效一会是dummytext和应标记为＆LT; T2＆GT; dummytext＆LT; / T2方式＆gt;

我认为应该可以创建此一个bash shell脚本的解决方案，而不是依靠的Perl / Python的/ Ruby程序。

解决方案

纯巴什（无外部）

在bash命令行：

  $ sample=\"LoremIpsumissimplydummytextoftheprintingandtypesettingindustry.LoremIpsumhasbeentheindustry'sstandarddummytexteversincethe1500s,whenanunknownprintertookagalleyoftypeandscrambledittomakeatypespecimenbook.\"
$＃或：样品= $（小于sample1.txt）
$阵列=（
LoremIpsum
LoremIpsu
dummytext
...
）
$标签= 0;在$ {数组[@]}项;做测试=＆LT; [^＆GT; / *＆GT; [^＆GT;] * $入门[^＆LT;] *＆LT; /;如果[！ $样品=〜$测试]];然后（（标签++））;样品= $ {//示例$ {}进入/＆LT; T $标记＆GT; $输入＆LT; / T $标签＆GT;};网络连接;完成的;回声输出;回声$样本
输出：
<T1>LoremIpsum</T1>issimply<T2>dummytext</T2>oftheprintingandtypesetting<T3>industry</T3>.<T1>LoremIpsum</T1>hasbeenthe<T3>industry</T3>'sstandard<T2>dummytext</T2>eversincethe1500s,whenanunknownprintertookagalleyoftypeandscrambledittomakeatypespecimenbook.
 

This is linked to another question/code-golf i asked on http://stackoverflow.com/questions/3171552/code-golf-color-highlighting-of-repeated-text

I've got a file 'sample1.txt' with the following content:

LoremIpsumissimplydummytextoftheprintingandtypesettingindustry.LoremIpsumhasbeentheindustry'sstandarddummytexteversincethe1500s,whenanunknownprintertookagalleyoftypeandscrambledittomakeatypespecimenbook.

I've got a script generating the following array of strings which occur in the file (only a few shown for illustration):

LoremIpsum
LoremIpsu
dummytext
oremIpsum
LoremIps
dummytex
industry
oremIpsu
remIpsum
ummytext
LoremIp
dummyte
emIpsum
industr
mmytext

I need to (from the top) see if 'LoremIpsum' occurs in file sample1.txt. If so, I want to replace all occurences of LoremIpsum with: <T1>LoremIpsum</T1>. Now, when the program moves to the next word 'LoremIpsu', it should NOT match against the <T1>LoremIpsum</T1> text inside sample1.txt. It should repeat the above for all elements of this 'array'. The next 'valid' one would be 'dummytext' and that should be tagged as <T2>dummytext</T2> .

I do think it should be possible to create a bash shell script solution for this rather than relying on perl/python/ruby programs.

解决方案

Pure Bash (no externals)

At the Bash command line:

$ sample="LoremIpsumissimplydummytextoftheprintingandtypesettingindustry.LoremIpsumhasbeentheindustry'sstandarddummytexteversincethe1500s,whenanunknownprintertookagalleyoftypeandscrambledittomakeatypespecimenbook."
$ # or: sample=$(<sample1.txt)
$ array=(
LoremIpsum
LoremIpsu
dummytext
...
)
$ tag=0; for entry in ${array[@]}; do test="<[^>/]*>[^>]*$entry[^<]*</"; if [[ ! $sample =~ $test ]]; then ((tag++)); sample=${sample//${entry}/<T$tag>$entry</T$tag>}; fi; done; echo "Output:"; echo $sample
Output:
<T1>LoremIpsum</T1>issimply<T2>dummytext</T2>oftheprintingandtypesetting<T3>industry</T3>.<T1>LoremIpsum</T1>hasbeenthe<T3>industry</T3>'sstandard<T2>dummytext</T2>eversincethe1500s,whenanunknownprintertookagalleyoftypeandscrambledittomakeatypespecimenbook.
