Visual block in VI

Do you need to perform multiple line edits at a single stretch.

I came across VISUAL BLOCK in vi editor.

   CTRL + v makes you to enter the visual mode for your file.
   select multiple lines
   SHIFT + i gives you the insert mode
   Enter the text at beginning of the block
   Press ESC twice to apply changes to all lines.

Making your vi for default settings

If you want your vi editor to load with default settings (i.e) the line number to be displayed and also tabspace to set for 4 characters.

Here the way to do...

create a file ~/.exrc with settings

set nu
set tabstop=3

Then opening the vi will have these settings common for all.
