我有一个这样的文件，我需要用sed命令替换所有字符串行，例如我想在＆＃34; Branglebracken＆＃34;上使用sed。并替换为其他想要的文本，但我不想在其他字符串中包含此单词时替换它。我的意思是我只需要单独替换它，而不是将其包含在其他文本中时才需要替换它。所以基本上它必须以它开始和结束......
I came here to Branglebracken with my wife and child, as well as an Altmer herbalist who wanted to explore the forest.\n\nCould you check on them? Since they're not back already, I assume they've taken a rest at the wayshrine to the northwest.

您可以使用锚点将匹配仅限制为一行中的搜索模式：
sed 's/^Branglebracken$/word-replaced/' file
^和$将确保您只在一行中匹配Branglebracken。
