Vi ​

For a while, when doing system administration work on remote servers, vi was one of the few editors that could be counted on to be installed.

vi is everywhere. It's good to understand the different modes so that you can accomplish basic editing.

Configuration ​

See .exrc for a simple startup script that will map ctrl-j to print a timestamp.

The below settings can be added to a configuration file

vi ~/.vimrc

vi ~/.vimrc

add the desired setting as new line without the colon:

set paste

set paste

Settings ​

Line numbers can be helpful in certain contexts, especially when working together

:set number

:set number

Another useful one is

:set paste

:set paste

That way when pasting text and a comment shows up, you won't get all of the subsequent lines with comment prefixes added

nano ​

Many systems also include nano, which also works when you need an editor over a console.
