Vim (Vi improved) is a text editor based on the vi text editor. It can be used from the command-line or as a standalone application with a graphical user interface.

If X Window System support is not needed, install app-editors/vim:
emerge --ask app-editors/vim
emerge --ask app-editors/gvim
The category app-vim provides a lot of additional syntax definitions, plugins and other Vim related stuff.
Use emerge or eix to get an overview of available packages in the app-vim category:
emerge --search "%@^app-vim"
eix -cC app-vim
Vim can be configured on a per-user basis or through a system-wide configuration file:
- /etc/vim/vimrc - The system wide (global) settings file.
- ~/.vimrc - The user-specific (local) configuration file. The tilde (~) means it is in the user's home directory.
Vim has a built-in tutorial which should require around 30 minutes to go through. Start it using the vimtutor command:
About a dozen color schemes are shipped with the base Vim package. They can be listed in last line mode by typing colorscheme, then pressing either Ctrl+d or pressing the Tab key twice:
blue darkblue default delek desert elflord evening industry koehler morning murphy pablo peachpuff ron shine slate torte zellner
They can be changed in Vim by using the colorscheme (alternatively use colo) command while in last line mode:
Color schemes can be permanently applied in the .vimrc file:
colorscheme peachpuff syntax on
The first line sets the default color scheme while the last line activates the color scheme.
Tips and tricks
Using Vim like ex or ed from the command line
It is possible to use Vim for one-liners — commands that can be used in scripts or on the command-line to make changes in an unattended manner.
For instance, the following command adds
# to the beginning of each line in the file.txt file:
vim -c ":%s/^/#/g" -c ":x" file.txt
What happens is that Vim interprets the passed on commands (through the
-c option). The first command is Vim's substitution command (which is very similar to sed's), the second one is Vim's instruction to save and exit the editor.
Change file encoding
To change the file encoding of a file to UTF-8, use the following command (in last line mode):
As shown in the previous trick, it is possible to do this from the command line as well:
vim -c ":wq! ++enc=utf8" file.txt
