Perl替换中的反斜杠

Question

I'm trying my luck with a perl one-liner changing some commands in a bunch of .tex files. I got as far as the following:

perl -pi -e "s/\Q\linenum{some more stuff}\E/\Q\uln\E/g" *tex

Which results in \\lLn instead of the expected replacement patter \\uln\u003c/code> . Apparently while \\Q and \\E take care of other special characters, they don't take care of the \\l \\u\u003c/code> changing the case of the next character, how would I do that?

Answer 1

\\Q\\E works best for \\Q$var\\E . Elsewhere, you can use \\ to escape characters that need escaping.

perl -i -pe's/\\linenum\{some more stuff\}/\\uln/g' *tex
