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.
