I tried doing the following command on a new install of Ubuntu and got a "Sorry, command not supported on this version message":
How could any version of vim not support echo? The reported version is 7.4 Small version without GUI.
Ubuntu comes packaged with a tiny version of vim. It is nearly vi. To install the real version of vim, run
sudo apt-get install vim
Personally, I prefer:
sudo apt-get install vim-gnome
since this comes with things like python and clipboard support, and gvim, but installing the default vim version should be enough to get echo working.
I don't remember exactly what the difference between the two is, and I don't have Ubuntu set up so I can't test it right now, but
apt-get install vim should come with the sane defaults and
apt-get install vim-gnome should get you the full features.
you got a small version of Vim installed. That means, many functions are not supported, you can read about, what each flavor supports at
:h +feature-list (link).
So among the features not supported are multibyte, eval (plugins), diff, folding and quickfix.
The easiest solution to get a better full-working Vim is to install vim-gtk (full version with GTK Gui), vim-nox (full version without gui support) or vim-gnome (full version with Gnome Support)
echo command depends on the
eval feature. The
eval faeture is compiled in only in models
normal and larger.
