我的要求比现有答案here稍微复杂一些。
\addplot3[%

以上是一段代码，它使用不同的rgb值重复多次。因此，简单的搜索和替换不起作用。
我想用以下内容替换上面的块：
\addplot3[%
surf, z buffer=sort, colormap={my}{rgb255=(20,20,20) rgb255=(50,50,50) rgb255=(250,250,250) }, mesh/rows=21]
每次更换的内容都相同。
如上所述，我在上面的回答链接中尝试\addplot3[为WORD1而},为WORD2，我的要求surf, z buffer=sort, colormap={my}{rgb255=(20,20,20) rgb255=(50,50,50) rgb255=(250,250,250)为WORD3 ：
sed -i 's/(\addplot3[).*(},)/\1 surf, z buffer=sort, colormap={my}{ rgb255=(20,20,20) rgb255=(50,50,50) rgb255=(250,250,250) \2/g' multiparticle_random.tex
我收到以下错误：
sed: -e expression #1, char 126: unterminated `s' command
有人可以帮助您成功完成此搜索并替换操作吗？
欢迎适用于sed以外的Linux的解决方案。
答案 0 :(得分：0)
首先应匹配以\\addplot3\[%开头的行（观察转义字符），然后将下一行读入模式空间（sed一次占用一行）并执行替换命令。要捕获使用sed（POSIX BRE）的群组，您应该将其转义\(...\)或使用-r选项：
sed '/\\addplot3\[%/{N;s/\(.*\)\n.*\(},.*\)/\1 surf, z buffer=sort, colormap={my}{ rgb255=(20,20,20) rgb255=(50,50,50) rgb255=(250,250,250) \2/g}' file
