  30 .SH DESCRIPTION
  31 The GNU
  32 .B objcopy
  33 utility copies the contents of an object file to another.
  34 .B objcopy
  35 uses the GNU BFD Library to read and write the object files.  It can
  36 write the destination object file in a format different from that of
  37 the source object file.  The exact behavior of
  38 .B objcopy
  39 is controlled by command-line options.
  40 .PP
  41 .B objcopy
  42 creates temporary files to do its translations and deletes them
  43 afterward.
  44 .B objcopy
  45 uses BFD to do all its translation work; it knows about all the
  46 formats BFD knows about, and thus is able to recognize most formats
  47 without being told explicitly.
  48 .PP
  49 .I infile
  50 and
  51 .I outfile
  52 are the source and output files respectively.  If you do not specify
  53 .IR outfile ,
  54 .B objcopy
  55 creates a temporary file and destructively renames the result with the
  56 name of the input file.
  57
  58 .SH OPTIONS
  59 .TP
  60 .B \-I \fIformat
  61 .TP
  62 .B \-\-input\-format=\fIformat
  63 Consider the source file's object format to be
  64 .IR format ,
  65 rather than attempting to deduce it.
  66 .TP
  67 .B \-O \fIformat
  68 .TP
  69 .B \-\-output\-format=\fIformat
  70 Write the output file using the object format
  71 .IR format .
  72 .TP
  73 .B \-F \fIformat\fB
  74 .TP
  75 .B \-\-format=\fIformat
  76 Use
  77 .I format
  78 as the object format for both the input and the output file; i.e.
  79 simply transfer data from source to destination with no translation.
  80 .TP
  81 .B \-S
  82 .TP
  83 .B \-\-strip\-all
  84 Do not copy relocation and symbol information from the source file.
  85 .TP
  86 .B \-g
  87 .TP
  88 .B \-\-strip\-debug
  89 Do not copy debugging symbols from the source file.
  90 .TP
  91 .B \-x
  92 .TP
  93 .B \-\-discard\-all
  94 Do not copy non-global symbols from the source file.
  95 .TP
  96 .B \-X
  97 .TP
  98 .B \-\-discard\-locals
  99 Do not copy compiler-generated local symbols. (These usually start
 100 with "L" or ".").
 101 .TP
 102 .B \-v
 103 .TP
 104 .B \-\-verbose
 105 Verbose output: list all object files modified.  In the case of
 106 archives, "\fBobjcopy \-V\fR" lists all members of the archive.
 107 .TP
 108 .B \-V
 109 .TP
 110 .B \-\-version
 111 Show the version number of
 112 .B objcopy
 113 and exit.
 114 .TP
 115 .B \-\-help
 116 Show a summary of the options to
 117 .B objcopy
 118 and exit.
