About fb
fb
is a utility for the viewing and editing of binary files. Files can be viewed in binary, decimal, hexadecimal, and octal, and/or characters. In addition to simple overwriting, a binary file may be dumped as binary, hexadecimal, decimal, or octal numbers; edited with one's favorite text editor; and then translated back into a binary file.
fb
also has methods for appending and copying sections of a file, replacing sections of a file with a particular value, and a method for comparing files: showing differences in either binary, decimal, hexadecimal, or octal.
