Ubuntu Linux: Install vim Text Editor

in Categories , , last updated March 21, 2016

I recently switched from OS X to Ubuntu. When I run the ‘vim file.c’ command at terminal, I see an error message that read as follows:

The program ‘vim’ can be found in the following packages:
* vim
* vim-gnome

* vim-tiny
* vim-athena
* vim-gtk
* vim-nox
