如何在 MacOS 上使用 sed 删除包括反斜杠在内的模式？
How to use sed to delete patterns including backslash on MacOS?
我正在尝试使用 sed 删除诸如“\subsection{sometext}”之类的模式，
所以来自：
Important astrophysical issues could be solved...
\subsection{ Introduction\good line}
\subsection{? apple $ fast burry }white
abc
我要：
Important astrophysical issues could be solved...
white
abc
我试过：
sed -E -i '' 's/\(section|subsection|subsubsection)\{([^\}]+)\}//g' test.tex
但结果是：
Important astrophysical issues could be solved...
\subsection{ Introduction\good line}
white
abc
似乎包含反斜杠的文本无法匹配。我使用 MacOS。
}里面的[]不需要转义，所以：
's/\(section|subsection|subsubsection)\{([^}]+)\}//g'
简单有效。
你可以在re_format(7)中看到规则：
... With the exception of these and some combinations using `[' (see next paragraphs), all other special characters, including `\', lose their special significance within a bracket expression.
