Editors Interview Question:

What is the difference between lettered buffer and temporary buffer?

Submitted by: Administrator

Temporary Buffer

Deleted or copied text goes into a temporary unnamed
buffer. The contents of the temporary buffer may be
retrieved by using the p or P commands.

Lettered Buffers

There are 26 lettered buffers (a-z). Contents of a lettered
buffer are saved until you copy or delete more characters
into it, or until you quit your current vi session.

eg.
From Command Mode

"ayy Copy (yank) a line into buffer letter "a"
"ap Put contents of lettered buffer a below the
current line
