It should be noted that this also occurs in almost every programming language where "\" is the escape character. i.e.
print("Hello") > Hello print("\"Hello\"") > "Hello" print("\\Hello\\") > \Hello\

- I don't think the regex is invalid
According to man grep you need to specify the -E option to use extended regex; without it unescaped parentheses are not interpreted, so they don't need to match.
My - very wild - guess is that it was the command he used to find the line with the most special characters, but I am not confident enough to edit the article (if someone can confirm?). 141.101.66.83 (talk) (please sign your comments with ~~~~)
If it was supposed to do that, it doesn't work. Running it on my bash history matches no lines, and I have lots of special characters in there 197.234.242.243 07:12, 3 February 2016 (UTC)
Explain it to me like I'm dumb. What is this comic going on about? I think the explanation needs more examples like that hello, above, because that's almost understandable. --198.41.238.231 07:47, 3 February 2016 (UTC)
This is the third time Randall has mentioned Ba'al the Soul Eater xD International Space Station (talk) 08:26, 3 February 2016 (UTC)
After passing the regex through bash, you get \\[[(].*\\[\])][^)\]]*$ That is, the literal character \, followed by [ or (, followed by any number of any characters, followed by \, followed by ] or ), followed by any number of characters that aren't ) or ], until the end of the line. 108.162.216.44 08:33, 3 February 2016 (UTC)
