.SH DESCRIPTION
GNU \c
.B nm\c
-\& will list the symbols from object files \c
-.I objfiles\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
-.IR "objfiles" .\|.\|.
-Object files whose symbols are to be listed. If no object files are
-listed as arguments, \c
-.B nm\c
-\& assumes `\|\c
-.B a.out\c
-\|'.
+.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
+.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 \-C
+.TP
+.B \-\-demangle
+Decode (\fIdemangle\fP) low-level symbol names into user-level names.
+Besides removing any initial underscore prepended by the system, this
+makes C++ function names readable.
+
+.TP
+.B \-D
+.TP
+.B \-\-dynamic
+Display the dynamic symbols rather than the normal symbols. This is
+only meaningful for dynamic objects, such as certain types of shared
+libraries.
+
+.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
+.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
+.B \-\-no\-sort
Don't bother to sort the symbols in any order; just print them in the
order encountered.
.TP
-.B \-n
+.B \-P
.TP
-.B +numeric-sort
-Sort symbols numerically by their addresses, not alphabetically by their
-names.
+.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
+.B \-\-print\-armap
When listing symbols from archive members, include the index: a mapping
(stored in the archive by \c
.B ar\c
\&) of what modules
contain definitions for what names.
-.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 \-r
.TP
-.B +reverse-sort
+.B \-\-reverse\-sort
Reverse the sense of the sort (whether numeric or alphabetic); let the
last come first.
.TP
-.BI "+target " "bfdname"\c
-\&
+.B \-\-size\-sort
+Sort symbols by size. The size is computed as the difference between
+the value of the symbol and the value of the symbol with the next higher
+value. The size of the symbol is printed, rather than the value.
+
+.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"
Specify an object code format other than your system's default format.
See
.BR objdump ( 1 ),
.TP
.B \-u
.TP
-.B +undefined-only
+.B \-\-undefined\-only
Display only undefined symbols (those external to each object file).
-.PP
+.TP
+.B \-l
+.TP
+.B \-\-line\-numbers
+For each symbol, use debugging information to try to find a filename and
+line number. For a defined symbol, look for the line number of the
+address of the symbol. For an undefined symbol, look for the line
+number of a relocation entry which refers to the symbol. If line number
+information can be found, print it after the other symbol information.
+
+.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.
