Usage: /usr/lib/gcc/x86_64-pc-linux-gnu/12/../../../../x86_64-pc-linux-gnu/bin/nm [option(s)] [file(s)] List symbols in [file(s)] (a.out by default). The options are: -a, --debug-syms Display debugger-only symbols -A, --print-file-name Print name of the input file before every symbol -B Same as --format=bsd -C, --demangle[=STYLE] Decode mangled/processed symbol names STYLE can be "none", "auto", "gnu-v3", "java", "gnat", "dlang", "rust" --no-demangle Do not demangle low-level symbol names --recurse-limit Enable a demangling recursion limit. (default) --no-recurse-limit Disable a demangling recursion limit. -D, --dynamic Display dynamic symbols instead of normal symbols -e (ignored) -f, --format=FORMAT Use the output format FORMAT. FORMAT can be `bsd', `sysv', `posix' or 'just-symbols'. The default is `bsd' -g, --extern-only Display only external symbols --ifunc-chars=CHARS Characters to use when displaying ifunc symbols -j, --just-symbols Same as --format=just-symbols -l, --line-numbers Use debugging information to find a filename and line number for each symbol -n, --numeric-sort Sort symbols numerically by address -o Same as -A -p, --no-sort Do not sort the symbols -P, --portability Same as --format=posix -r, --reverse-sort Reverse the sense of the sort --plugin NAME Load the specified plugin -S, --print-size Print size of defined symbols -s, --print-armap Include index for symbols from archive members --quiet Suppress "no symbols" diagnostic --size-sort Sort symbols by size --special-syms Include special symbols in the output --synthetic Display synthetic symbols as well -t, --radix=RADIX Use RADIX for printing symbol values --target=BFDNAME Specify the target object format as BFDNAME -u, --undefined-only Display only undefined symbols -U, --defined-only Display only defined symbols --unicode={default|show|invalid|hex|escape|highlight} Specify how to treat UTF-8 encoded unicode characters -W, --no-weak Ignore weak symbols --without-symbol-versions Do not display version strings after symbol names -X 32_64 (ignored) @FILE Read options from FILE -h, --help Display this information -V, --version Display this program's version number /usr/lib/gcc/x86_64-pc-linux-gnu/12/../../../../x86_64-pc-linux-gnu/bin/nm: supported targets: elf64-x86-64 elf32-i386 elf32-x86-64 pei-i386 pe-x86-64 pei-x86-64 elf64-little elf64-big elf32-little elf32-big srec symbolsrec verilog tekhex binary ihex plugin Report bugs to .
