Man, people have the weirdest fetishes for using the most unreadable acrobatic shell garbage you have ever seen.

Some StackOverflow answers are hilarious, like the question could be something like "how do I capture regex groups and put them in a variable array?".

The answer would be some multiline command using every goddamn character possible, no indentation, no spaces to make sense of the pieces.

Regex in unix is an unholy mess. You have sed (with its modes), awk, grep (and grep -P), egrep.
I'll take js regex anytime of the day.

And everytime you need to do one simple single goddamn thing, each time it's a different broken ass syntax.

The resulting command that you end up picking is something that you'll probably forget in the next hour.

I like a good challenge, but readability is important too.

Or maybe I have very rudimentary shell skills.
