Linux bfs command
Short for "Big File Scanner," bfs is a modified version of the ed editor that is read-only and designed to process much larger files.
The purpose of bfs is to load, view and analyze very large text files. It does not load the text into a buffer, and does not allow the contents to be modified.
The intended use of bfs is to examine a file to determine where it can be split into smaller files using csplit. The more manageable pieces can then be edited with ed.
