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 \-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 +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 \-\-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 ), +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 \-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. + +.SH "SEE ALSO" +.RB "`\|" binutils "\|'" +entry in +.B +info\c +\&; +.I +The GNU Binary Utilities\c +\&, Roland H.
