[英]Regex: Replace character between two strings (excluding the strings themselves) using sed
I have a minor problem. 我有一个小问题。 I want to replace a character/single string between two strings but would like to leave the strings themselves "unharmed" by using sed . 我想在两个字符串之间替换一个字符/单个字符串,但想通过使用sed使字符串本身“不受损害”。
The input is: 输入为:
<hello> <world>
My desired output: 我想要的输出:
<hello>
<world>
My first attempt: 我的第一次尝试:
echo "<hello> <world>" | sed 's/>.</\n/g'
The output of it: 它的输出:
<hello
world>
As you can see, the ">" from "" and the "<" from "" have been removed by using my line above. 如您所见,使用上面的行删除了“”中的“>”和“”中的“ <”。
How do I prevent it from doing so? 我如何防止它这样做?
这个也可以:
echo "<hello> <world>" | sed 's/>./>\n/g'
Instead use: 而是使用:
echo "<hello> <world>" | sed 's/>.</>\n</g'
This is possible all the characters you are replacing are static. 这可能是您要替换的所有字符都是静态的。
