.SH DESCRIPTION
GNU \c
.B nm\c
\& lists the symbols from object files \c
.I objfile\c
\&. If no object files are given as arguments, \c
.B nm\c
\& assumes `\|\c
.B a.out\c
\|'.
.SH OPTIONS
The long and short forms of options, shown here as alternatives, are
equivalent.
.TP
.B \-A
.TP
.B \-o
.TP
.B \-\-print\-file\-name
Precede each symbol by the name of the input file where it was found,
rather than identifying the input file once only before all of its
symbols.
.TP
.B \-a
.TP
.B \-\-debug\-syms
Display debugger-only symbols; normally these are not listed.
.TP
.B \-B
The same as
.B \-\-format=bsd
(for compatibility with the MIPS \fBnm\fP).
.TP
.B "\-f \fIformat"
Use the output format \fIformat\fP, which can be ``bsd'',
``sysv'', or ``posix''. The default is `bsd''.
Only the first character of \fIformat\fP is significant; it can be
either upper or lower case.
.TP
.B \-g
.TP
.B \-\-extern\-only
Display only external symbols.
.TP
.B \-n
.TP
.B \-v
.TP
.B \-\-numeric\-sort
Sort symbols numerically by their addresses, not alphabetically by their
names.
.TP
.B \-p
.TP
.B \-\-no\-sort
Don't bother to sort the symbols in any order; just print them in the
order encountered.
.TP
.B \-P
.TP
.B \-\-portability
Use the POSIX.2 standard output format instead of the default format.
Equivalent to ``\-f posix''.
.TP
.B \-s
.TP
.B \-\-print\-armap
When listing symbols from archive members, include the index: a mapping
(stored in the archive by \c
.B ar\c
\& or \c
.B ranlib\c
\&) of what modules
contain definitions for what names.
.TP
.B \-r
.TP
.B \-\-reverse\-sort
Reverse the sense of the sort (whether numeric or alphabetic); let the
last come first.
.TP
.B "\-t \fIradix"
.TP
.B "\-\-radix=\fIradix"
Use \fIradix\fP as the radix for printing the symbol values. It must be
``d'' for decimal, ``o'' for octal, or ``x'' for hexadecimal.
.TP
.BI "\-\-target=" "bfdname"\c
\&
Specify an object code format other than your system's default format.
See
.BR objdump ( 1 ),
for information on listing available formats.
.TP
.B \-u
.TP
.B \-\-undefined\-only
Display only undefined symbols (those external to each object file).
.TP
.B \-V
.TP
.B \-\-version
Show the version number of
.B nm
and exit.
.TP
.B \-\-help
Show a summary of the options to
.B nm
and exit.
