Work in Bash does not rely on functions the way functional
programming does, instead it relies on shell tools that aren't
part of Bash, e.g. the GNU toolchain.

Now, with so many people using Bash and other even more
feature-rich shells (where "save a fork" has been a focus of
development) there should be enough functions even compared to
what you find in Lisp.

Lisp is a fringe/underground language while every and any kid
with a Linux box uses the shell.

But some people actually think first what tool(s) are suited
for a particular task. Again, you _can_ hit a nail with the
flip side of an axe. However that doesn't make it a smart
thing to do! And if you rely on that in general you'll be the
laughing stock of the wood shop/carpentry ...

Of course you can reuse shell scripts and functions ...
