Isn't ` being deprecated (by BASH at least) anyway?
Hopefully not! It's just two key presses to type "``". "$()" takes 4
(shift+4+9, command, shift+0).
$() is more consistent with other syntax elements in bash, It's essentially
the same thing as evaluating a variable and inserting it's value. The ``
syntax is a wild anachronism from days long ago that is completely at odds
with everything else in the shell. Well, you can say that about many things in
bash, but that's not a good reason to not fix anything...
IIRC correctly it's not really deprecated either - that implies the thing will
go away some time. It's more "strongly advised not to use it"
I think you're confusing script usage vs interactive CLI usage.
What's easier than simply pressing one single key? :-/
Ummm, not having to look for it and find it first before pressing it?
That's true for every key. But I bet you learned how to do shift+4 to
get an $, right? Well, it's much easier to learn how to press ` to get
an... ` ;)
How about a keyboard that doesn't have it at all?
Don't know, I've never saw one.
