NAME
nm - name list dump of MIPS object files
SYNOPSIS
nm [-abdefghnopruvxABTV] [ file1 ... fileN ]
DESCRIPTION
The nm command prints listings formats for the symbol and
external sections of the symbol table. A file can be an
object or an archive. If you do not specify a file, this
command assumes a.out.
The -A and -B options specify AT&T System V style output or
Berkeley (4.3
BSD) style output, respectively. The version of UNIX run-
ning at your site determines the default. NOTE: Some
options can change the version-specific defaults. These
options change the meaning of overloaded flags after -A or
-B is specified.
A normal Berkeley system produces the address or value field
followed by a letter showing what section the symbol or
external is in and the name of the symbol or external.
These section letters describe the information that nm gen-
erates
N nil storage class, compiler internal usage
T external text
t local text
D external initialized data
d local initialized data
B external zeroed data
b local zeroed data
A external absolute
a local absolute
U external undefined
G external small initialized data
g local small initialized data
S external small zeroed data

s local small zeroed data
R external read only
r local read only
C common
E small common
V external small undefined
The standard System V format and the -a specified Berkeley
format provide an expanded listing with these columns:
Name the symbol or external name
Value
the value field for the symbol or external, usu-
ally an address or interesting debugging informa-
tion
Class
the symbol type
Type the symbol's language declaration
Size unused
Index
the symbol's index field
Section
the symbol's storage class
NOTE: Every effort was made to map the field's functionality
into System V nomenclature.
The nm command accepts these options:
-a prints debugging information, effectively turning
Berkeley into System V format
-b prints the value field in octal
-d prints the value field in decimal (the System V
default)
-e prints external and statics only
-f produces full output-nm still accepts this old
option, but ignores it

-h does not print headers
-n for System V, sorts external symbols by name
(default for Berkeley), and for Berkeley, sorts
all symbols by value
-o for System V, prints the value field in octal, and
for Berkeley prepends the filename to each
symbol-good for grepping through nm of libraries
-p prints symbols as they are found in the file (the
System V default)
-r reverses the sense of a value or name sort
-u prints only undefined symbols
-v sorts external symbols by value
-x prints value field in hexadecimal (Berkeley
default)
-T truncates long names, inserting a `*' as the last
printed character
-V prints version information on stderr
