The '''GNU Binary Utilities''', or {{mono|'''binutils'''}}, is a collection of [[programming tool]]s maintained by the [[GNU Project]] for working with [[executable]] code including [[Assembler (computing)|assembly]], [[Linker (computing)|linking]] and many other development operations.

The tools are originally from [[Cygnus Solutions]].

The tools are typically used along with other GNU tools such as [[GNU Compiler Collection]], and the [[GNU Debugger]].

==Tools==

The tools include:

{| class="wikitable"
|-
| <code>[[GNU Assembler|as]]</code> || [[Assembly language#Assembler|assembler]] popularly known as GAS (GNU Assembler)
|-
| <code>[[GNU linker|ld]]</code> || [[Linker (computing)|linker]]
|-
| <code>[[gprof]]</code> || [[profiling (computer programming)|profiler]]
|-
| <code>[[addr2line]]</code> || convert address to file and line
|-
| <code>[[ar (Unix)|ar]]</code> || create, modify, and extract from [[archive file|archives]]
|-
| <code>c++filt</code> || [[name mangling#Name mangling in C++|demangling]] filter for [[C++]] symbols
|-
| <code>dlltool</code> || creation of Windows [[dynamic-link library|dynamic-link libraries]]
|-
| <code>[[gold (linker)|gold]]</code> || alternative linker for [[Executable and Linkable Format|ELF]] files
|-
| <code>nlmconv</code> || object file conversion to a [[NetWare Loadable Module]]
|-
| <code>[[nm (Unix)|nm]]</code> || list symbols exported by object files
|-
| <code>objcopy</code> || copy object files, possibly making changes
|-
| <code>[[objdump]]</code> || dump information about object files
|-
| <code>[[ranlib]]</code> || generate indices for archives (for compatibility; same as {{code|ar -s}})
|-
| <code>[[readelf]]</code> || display contents of [[Executable and Linkable Format|ELF]] files
|-
| <code>size</code> || list section sizes and total size of binary files
|-
| <code>[[strings (Unix)|strings]]</code> || list printable strings
|-
| <code>[[strip (Unix)|strip]]</code> || remove symbols from object files
|-

|-
| <code>windres</code> || compiler for Windows [[Resource (Windows)|resource]] files

==elfutils==
Ulrich Drepper wrote {{mono|elfutils}}, to partially replace GNU Binutils, purely for [[Linux]] and with support only for [[Executable and Linkable Format|ELF]] and [[DWARF]]. It distributes three libraries with it for programmatic access.<ref>[https://sourceware.org/elfutils/ elfutils home]</ref><ref>[https://www.akkadia.org/drepper/ elfutils at Drepper's home]</ref>
