Linux bfs command
bfs is considered a Unix heirloom (legacy) program, and may not be available for installation by your operating system's package manager.
bfs loads, views and analyzes 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.
