nuke big file scanner (bfs)
The description of bfs from the manpage:
The bfs command is (almost) like ed(1) except that it is read-only and processes much larger files. Files can be up to 1024K bytes and 32K lines, with up to 512 characters, including new-line, per line (255 for 16-bit machines).
Given the limitations, this utility is essentially worthless.

Finally, for what its worth, I've heard that Oracle is removing bfs from Solaris.
