Yes, but it is not installed as the default text editor. Unlike vi/vim/nano
The default is usually vi or nano, not full vim. So installing vim or neovim should take about the same effort.
In what distros? Ubuntu comes with vim.
Debian Stable (without a DE) only comes with nano AFAIK.
I'd bet good money both ed and vi are there as they are specified by POSIX iirc.
It has vi in the base system, specifically `vim-tiny`. Vi is mandated by POSIX, so pretty much every distro includes some minimal version of it in the base system. `nvi` is also used sometimes instead.
Yeah, but it's vim.tiny. They don't even alias it to `vim` because it's not full vim.
It's in the official repos for many distros including OpenSUSE.
I actually am fixing up the install documents even though I don't use Neovim
