This same format was used to display memory when invoking the D command in the standard CP/M debugger DDT. [3]: 4-5 Later incarnations of the format (e.g. in the DOS debugger DEBUG) changed the space between the 8th and 9th byte to a dash, without changing the overall width. Data Display Debugger (GNU DDD) is a graphical user interface (using the Motif toolkit) for command-line debuggers such as GDB, [2] DBX, JDB, HP Wildebeest Debugger, [note 1] XDB, the Perl debugger, the Bash debugger, the Python debugger, and the GNU Make debugger. [4] DDD is part of the GNU Project and distributed as free software under the GNU General Public License. The GNU Debugger (GDB) is a portable debugger that runs on many Unix-like systems and works for many programming languages, including Ada, Assembly, C, C++, D, Fortran, Haskell, Go, Objective-C, OpenCL C, Modula-2, Pascal, Rust, [1] and partially others. [2] It detects problems in a program while letting it run and allows users to examine different registers. Intel hexadecimal object file format, Intel hex format or Intellec Hex is a file format that conveys binary information in ASCII text form, [10] making it possible to store on non-binary media such as paper tape, punch cards, etc., to display on text terminals or be printed on line-oriented printers. [11] An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections. In computing, the Executable and Linkable Format[3] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, device drivers, and core dumps. First published in the specification for This is a list of computer file formats, categorized by domain. Some formats are listed under multiple categories. Each format is identified by a capitalized word that is the format's full or abbreviated name. The typical file name extension used for a format is included in parentheses

if it differs from the identifier, ignoring case. The use of file name extension varies by operating system In computing, a core dump, [a] memory dump, crash dump, storage dump, system dump, or ABEND dump[1] consists of the recorded state of the working memory of a computer program at a specific time, generally when the program has crashed or otherwise terminated abnormally. [2] stabs was an early format for debugging symbols on Unix-like systems. The newer DWARF format, for which formal specifications exist, has largely supplanted it. The specification allows any compatible compiler or assembler to create debug symbols in a standardized format, and for any debugger, such as the GNU Debugger (GDB), to gain access and display these symbols.
