By "you" do you mean me, personally?

The servers I use do not have bash installed by default.

The only time I use it is when I am forced to by an installation script.

I install bash on an as needed basis, and when I'm done using it, I uninstall it. I just have no need for it otherwise.

What is the shell on Android? Is it bash?

No, definitely meant it as a general thing. And really, directed towards people working with servers, and not to people working with embedded devices (like Android) where keeping to POSIX (or specifically ash, which is what android and busybox use) is probably a necessity.

Many servers don't have bash installed as part of their base distribution, but if they're going to have another shell already installed it's much more likely to be bash than zsh.
