n m - Prints name list.
Syntax
nm [ -acgnoOprsSuv ] [ + offset ] [ file 1 ...
Description
nm prints the name list (symbol table) of each object file in the argument list. If an
argument is an archive, a listing for each object file in the archive will be produced. If
no file is given, the symbols in a.out are listed.
Each symbol name is preceded by its value in hexadecimal (blanks if undefined) and one
of the letters U (undefined), A (absolute), T (text segment symbol), D (data segment
symbol), B (bss segment symbol), C (common symbol), or K (8086/286 common segment).
If the sym bol table is in segmented format, symbol values are displayed as
segment:offset. If the symbol is local (nonexternal), the type letter is in lowercase.
The output is sorted alphabetically.
Options are
-a Print only absolute symbols.
-c Print only C program symbols (symbols that begin with "_") as they appeared in
the C program.
-g Print only global (external) symbols.
-n Sort numerically rather than alphabetically.
-o Prepend file or archive element name to each output line rather than only once.
-0 Print symbol values in octal.
-p Don't sort; print in symbol-table order.
-r Sort in reverse order.
-s Print 8086/286-executable file symbols as segment:offset.
-s Sort by size of symbol and display each symbol's size instead of value. The last
symbol in each text or data segment may be assigned a size of 0. This option
implies the -n option.
-u Print only undefined symbols.
-v Also describe the object file and symbol table format.
