Projects / bbe


bbe is a sed-like editor for binary files. Instead of reading input in lines as sed, bbe reads arbitrary blocks from an input stream and performs byte-related transformations on found blocks. Blocks can be defined using start/stop strings, stream offset and block length, or a combination. Basic editing commands include delete, replace, search/replace, binary operations (and, or, etc.), append, and bcd/ASCII conversion. For examining the input stream, it contains some grep-like features like printing the input file name, stream offset, and block number of found blocks. Block contents can also be printed in different formats like hex, octal, ASCII, and binary.
