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. --[[Special:Contributions/198.41.238.231|198.41.238.231]] 07:47, 3 February 2016 (UTC)

:Yes, that was already mentioned a few hours before you comment, see the first comment. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:51, 3 February 2016 (UTC)

:It sounds like you know what you are talking about. Anyone who can explain it good enough for the explanation, and correct the explanation of the title text if it is wrong to say that it would not work. I have added this as the reason for incomplete. But maybe also examples are needed for people with not programming skills/knowledge. We also enjoy xkcd ;-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:51, 3 February 2016 (UTC)

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\

Oh, and by the way, isn't this the third comic to mention "Ba'al, the Soul Eater"? Maybe we should start a category. (Others are 1246 (title text) and 1419.) 173.245.54.29 06:14, 3 February 2016 (UTC)

Did that before seeing you comment, so yes I agree. --Kynde (talk) 09:47, 3 February 2016 (UTC)
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)
