In comparison to Janis's answer this is not a complete rewrite of hexdump, but instead hexdump is called with the specified other parameters if given. If -n is specified then the output gets split at linebreaks, if not normal hexdump is called. It got me back to the gdb docs, and close to an appropriate page 1. ![]() For example, a web designer would use the hex value FF0000 to define the color red. This function adds a -n option to hexdump. The main reason for the design of this format is that it fits the maximum amount of data on a standard 80-character-wide screen or printer, while still being very easy to read and skim visually. Hex: F4240 Decimal: 1,000,000 Binary: 1111 0100 0010 0100 0000 Another place hexadecimal is used is as an HTML color code to express a specific color. On Linux systems, the command hexcat produces this classic output format too. In the Hex Dump mode, the printer produces an exact printout of the codes it receives. This notation has been retained in operating systems that were directly or indirectly derived from CP/M, including DR-DOS, MS-DOS, OS/2 and Windows. Hex Dump Mode Hex Dump mode (also called data dump) is a special feature that makes it easy for experienced users to find the cause of communication problems between the printer and the computer. in the DOS debugger DEBUG) changed the space between the 8th and 9th byte to a dash, without changing the overall width. This same format was used to display memory when invoking the D command in the standard CP/M debugger DDT. Bytes outside the standard range of printable ASCII characters (20 to 7E) would be displayed as a single period for visual alignment. In the CP/M 8-bit operating system used on early personal computers, the standard DUMP program would list a file 16 bytes per line with the hex offset at the start of the line and the ASCII equivalent of each byte at the end. ![]() ![]() In this output the TAB characters are displayed as \t and NEWLINE characters as \n. Linux binutils tools, such as objdump, gdb etc.
