fish, the friendly interactive shell, is a commandline shell intended to be interactive and user-friendly.
fish is intentionally not fully POSIX compliant, it aims at addressing POSIX inconsistencies (as perceived by the creators) with a simplified or a different syntax. This means that even simple POSIX compliant scripts may require some significant adaptation or even full rewriting to run with fish.
I really like Fish but for simple stuff like youtube-dl you always have to put quotation marks around the YouTube video’s address because Fish thinks the question mark is an operator. So annoying.
Fixed in fish 4.0 :)
Of course if you do find yourself in need of a single char wildcard or by extenaion a fixed length wildcard, you just don’t have that in fish.
