ANM(1) General Commands Manual ANM(1)NAME
anm - print name list
SYNOPSIS
anm [-gnoprus] file ...
OPTIONS -g Global symbols only
-n Sort numerically
-o Prepend the filename to each line
-p No sorting--use symbol table order
-r Sort in reverse order
-u List undefined symbols only
-s Sort in section order
EXAMPLES
anm -gn test.o # Print global symbols in numerical order
DESCRIPTION
Anm prints the name list (symbol table) of each ACK format object file in the argument list. If no file name is given, a.out is used.
Each symbol name is preceded by its value, a section indicator and a type indicator. The section indicators are:
U Undefined symbol
A Absolute symbol
- Other symbol
The type indicators are:
F Filename
M Module name
S Section name
E External (global) symbol
- Local symbol
The output is sorted alphabetically, unless otherwise specified. Notice that anm can only be used on ACK format object files (that is: .o
and .out files). If you want to get the name list of an executable program use nm instead.

nm -- display symbolic information in object files
SYNOPSIS
nm [--debug-syms] [--defined-only] [--demangle[=style]] [--dynamic] [--extern-only] [--help] [--line-numbers] [--no-demangle] [--no-sort]
[--numeric-sort] [--print-armap] [--print-file-name] [--print-size] [--radix=format] [--reverse-sort] [--size-sort] [--undefined-only]
[--version] [-A] [-B] [-C [style]] [-D] [-P] [-V] [-a] [-e] [-g] [-h] [-l] [-n] [-o] [-p] [-r] [-S] [-s] [-t format] [-u] [-x] file ...
DESCRIPTION
The nm utility displays symbolic information in the object files, executables, and object library files named by its arguments. Lack of sym-
bolic information in an otherwise valid input file, is not considered to be an error. If no files are specified on the command line, nm will
attempt to read a.out.
The nm utility recognizes the following options:
--debug-syms
Display all symbols, including debugger-only symbols.
--defined-only
Display only defined symbols.
--demangle[=style]
Decode (demangle) low-level symbol names into human-readable names. Supported values for argument style are 'auto', 'gnu-v2',
'gnu-v3' and 'arm.' If argument style is not specified, it is taken to be 'auto'.
--dynamic Only display dynamic symbols. This option is only meaningful for shared libraries.
--extern-only
Only display information about global (external) symbols.
--help Display a help message and exit.
--format=format
Display output in the format specified by argument format. Supported values for the format argument are 'bsd', 'sysv', and
'posix'. The default output format is 'bsd'.
--line-numbers
Display the filename and line number associated a symbol using any debugging information present in the input file. For defined
symbols, look up the line number associated with the address of the symbol. For undefined symbols, look up the line number
associated with a relocation entry that refers to the symbol. If line number information can be determined, it is displayed
after other symbol information.
--no-demangle
Do not demangle symbol names (default).
--no-sort Do not sort symbols.
--numeric-sort
Sort symbols numerically by address instead of alphabetically by name.
--print-armap
For ar(1) archives, include the index of the archive's members.
--print-file-name
Write the full pathname or library name of an object on each line, before the rest of the information for a symbol. If this
option is not specified, nm will only identify an input file once, before its symbols are listed.
--print-size
Print the size of each symbol instead of its value.
--radix=radix
Print numeric values using the specified radix. Supported values for argument radix are 'd' for decimal, 'o' for octal, and 'x'
for hexadecimal.
--reverse-sort
Reverse the order of the sort.
--size-sort Sort symbols by size instead of alphabetically by name.
--undefined-only
Display only undefined symbols.
--version Display the version identifier for nm and exit.
-A Equivalent to specifying option --print-file-name.
-B Equivalent to specifying option --format=bsd.
-C [style] Equivalent to specifying option --demangle[=style].
-D Equivalent to specifying option --dynamic.
-F format Equivalent to specifying option --format=format.
-P Equivalent to specifying option --format=posix.
-S Equivalent to specifying option --print-size.
-V Equivalent to specifying option --version.
-a Equivalent to specifying option --debug-syms.
-e Only display information for global and static symbols.
-f Produce full output (default).
-g Equivalent to specifying option --extern-only.
-h Equivalent to specifying option --help.
-l Equivalent to specifying option --line-numbers.
-n Equivalent to specifying option --numeric-sort.
-o If POSIX output was specified using the -F posix or -P options, this option is equivalent to specifying --radix='o'. If POSIX
output was not specified, this option acts as a synonym for the --print-file-name option.
-p Equivalent to specifying option --no-sort.
-v Equivalent to option -n.
-r Equivalent to specifying option --reverse-sort
-s Equivalent to specifying option --print-armap.
-t radix Equivalent to specifying option --radix=radix.
-u Equivalent to specifying option --undefined-only.
-x Write numeric values in hexadecimal (equivalent to -t x).
OUTPUT FORMAT
The nm utility can present its information in a number of formats, numeric radices and sort orders. By default nm uses BSD style output, a
hexadecimal radix, without output sorted alphabetically by name and without demangling of names.
For each symbol listed, nm presents the following information:
o The library or object name, if options -A or --print-file-name were specified.
o The symbol name.
o The type of the symbol denoted by a single character as below:
A A global, absolute symbol.
B A global ``bss'' (uninitialized data) symbol.
C A ``common'' symbol, representing uninitialized data.
D A global symbol naming initialized data.
N A debugger symbol.
R A read-only data symbol.
T A global text symbol.
U An undefined symbol.
V A weak object.
W A weak reference.
a A local absolute symbol.
b A local ``bss'' (uninitialized data) symbol.
d A local data symbol.
t A local text symbol.
v A weak object that is undefined.
w A weak symbol that is undefined.
? None of the above.
o The value of the symbol.
o The size of the symbol if applicable.
o Line number information, if available and if options -l or --line-numbers were specified.
EXIT STATUS
The nm utility exits 0 on success, and >0 if an error occurs.
