nm - print name list
nm [ -gnopru ] [ file ... ]
Nm prints the name list (symbol table) of each object file in the argu-
ment 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.
The output is sorted alphabetically.
-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 Don't sort; print in symbol-table order.
-r Sort in reverse order.
-u Print only undefined symbols.
