nm(1)
NAME
nm − print name list
SYNTAX
nm [ −gnopru ] [ file... ]
DESCRIPTION
The nm command 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 (blanks if undefined) and one of the letters U (undefined), A (absolute), T (text segment symbol), D (data segment symbol), B (bss segment symbol), or C (common symbol). If the symbol is local (non-external) the type letter is in lower case. If the a.out file is an overlay text executable (0430 or 0431), all text segment symbols are followed by their overlay text segment number. The output is sorted alphabetically.
OPTIONS
−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.
−p Do not sort. Print in symbol-table order.
−r Sort in reverse order.
−u Print only undefined symbols.
