  42 The long and short forms of options, shown here as alternatives, are
  43 equivalent.
  44
  45 .TP
  46 .IR "objfiles" .\|.\|.
  47 Object files whose symbols are to be listed.  If no object files are
  48 listed as arguments, \c
  49 .B nm\c
  50 \& assumes `\|\c
  51 .B a.out\c
  52 \|'.
  53
  54 .TP
  55 .B \-a
  56 .TP
  57 .B +debug-syms

  59
  60 .TP
  61 .B \-g
  62 .TP
  63 .B +extern-only
  64 Display only external symbols.
  65
  66 .TP
  67 .B \-p
  68 .TP
  69 .B +no-sort

  71 order encountered.
  72
  73 .TP
  74 .B \-n
  75 .TP
  76 .B +numeric-sort
  77 Sort symbols numerically by their addresses, not alphabetically by their
  78 names.
  79
  80 .TP
  81 .B \-s
  82 .TP
  83 .B +print-armap
  84 When listing symbols from archive members, include the index: a mapping
  85 (stored in the archive by \c
  86 .B ar\c
  87 \& or \c
  88 .B ranlib\c
  89 \&) of what modules
  90 contain definitions for what names.
  91
  92 .TP
  93 .B \-o
  94 .TP
  95 .B +print-file-name
  96 Precede each symbol by the name of the input file where it was found,
  97 rather than identifying the input file once only before all of its
  98 symbols.
  99
 100 .TP
 101 .B \-r
 102 .TP
 103 .B +reverse-sort
 104 Reverse the sense of the sort (whether numeric or alphabetic); let the

 106
 107 .TP
 108 .BI "+target " "bfdname"\c
 109 \&
 110 Specify an object code format other than your system's default format.
