vipe

vipe < stdin > stdout

vipe inserts a text editor into a Unix pipeline. It reads standard input into a temporary file, opens it in the editor specified by the EDITOR or VISUAL environment variable, and writes the edited content to standard output when the editor exits.This allows interactive modification of data flowing through a pipeline, which is useful for manually fixing input before it reaches the next command, debugging pipeline data, or performing one-off transformations that are easier to do in an editor than with sed or awk.
