匹配模式，将其保存在变量中，并使用sed/awk/grep将其追加到行的末尾
这是我过去4天一直在努力解决的问题。我读过谷歌和软件的教程，但没有一本能帮我。我把它作为一个问题扔在这里，以便其他人可以尝试并帮助我解决它。我已经用粗糙的方法解决了这个问题，但我在想是否有更聪明的方法。因此有一个包含滚珠轴承及其属性列表的文件。看起来是这样的：匹配模式，将其保存在变量中，并使用sed/awk/grep将其追加到行的末尾,awk,sed,Awk,Sed,这是我过去4天一直在努力解决的问题。我读过谷歌和软件的教程，但没有一本能帮我。我把它作为一个问题扔在这里，以便其他人可以尝试并帮助我解决它。我已经用粗糙的方法解决了这个问题，但我在想是否有更聪明的方法。因此有一个包含滚珠轴承及其属性列表的文件。看起来是这样的： <li class="odd first"> <a href="/productcatalogue/prodlink.html?lang=en&imperial=false&p

用于通用文本操作的UNIX工具是awk：
将HTML拖拽到机器可读的输出中是徒劳的。看看你是否能连接到最初产生HTML的任何东西。我正试图从一个网站上搜集一些数据，供我自己分析。所以我无法控制源代码。请使用正确的工具节省您的时间，尝试xmllint来完成此工作
