我正在将客户的本地站点迁移到 Drupal 7。这个过程需要一段时间——设计决策、一些新要求等。我相信你们都经历过。

我开始研究一个工具来（a）从旧数据库中获取 URL 路径列表，（b）从 Drupal 站点和旧站点获取每个页面的内容，（c）在页面上执行 xpath 查询以获取使用xidel的 div#maincontent 和 div#main 的内容，以及 (d) 将该数据保存在 new.txt 和 old.txt 文件中——同时保持与站点类似的文件夹结构以供参考。

收集数据.sh

#!/bin/bash
# get URLS
urls=$(ssh user@old_ser "~/data_urls.sh" | egrep "^\/" | sort -u)

# clear out current working folder
rm -rf ./working

# loop through paths
for i in $urls
do  

    # screen status update, set storage area with url_path in folder path, make folder
    echo $i
    storage_area=./working/$i/
    mkdir -p $storage_area


    # strip trailing space
    i=${i%/}

    # pull and and run xpath query
    xidel http://old_server$i  -e '//div[@id="maincontent"]//p' > $storage_area/old.txt
    xidel http://new_server$i -e '//div[@id="content"]//p' > $storage_area/new.txt

    # run a compare and output data into cmp.cmp
    cmp $storage_area/old.txt $storage_area/new.txt > $storage_area/cmp.cmp

done

辅助脚本循环遍历 cmp.cmp 文件的结果。

run_diff.sh

echo "------------------------------------------------------- "
echo "The following may have differences in content based on wdiff analysis"

for i in `find ./working/ -type d`; do

  better_url_name=`echo $i | sed -e 's#\./working##g'`


  echo -e "\e[1;37m"
  echo -----------------------------------------------------------------------
  echo http://old_server$better_url_name
  echo http://new_server$better_url_name
  echo -----------------------------------------------------------------------
  echo -e "\e[00m"
  wdiff -3s $i/old.txt $i/new.txt  | colordiff
done

上述结果产生如下内容。

-----------------------------------------------------------------------
http://old_server/career_services/career_fair.php
http://new_server/career_services/career_fair.php
-----------------------------------------------------------------------

我的问题：

  • 如何忽略这些误报？
  • 如何过滤掉空格和返回标记？
  • 这是正确的方法吗？我应该放弃这种方法，换成另一种会产生更好结果的方法吗？

使用diff命令，您可以使用以下选项 -

   -b  --ignore-space-change
         Ignore changes in the amount of white space.

   -w  --ignore-all-space
         Ignore all white space.

   -B  --ignore-blank-lines
         Ignore changes whose lines are all blank.

       --strip-trailing-cr
         Strip trailing carriage return on input.
