  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.

  58 .SH OPTIONS
  59 .TP
  60 .B \-I \fIformat\fR, \fB\-\-input\-format=\fIformat
  61 Consider the source file's object format to be
  62 .IR format ,
  63 rather than attempting to deduce it.
  64 .TP
  65 .B \-O \fIformat\fR, \fB\-\-output\-format=\fIformat
  66 Write the output file using the object format
  67 .IR format .
  68 .TP
  69 .B \-F \fIformat\fR, \fB\-\-format=\fIformat
  70 Use
  71 .I format
  72 as the object format for both the input and the output file; i.e.
  73 simply transfer data from source to destination with no translation.
  74 .TP
  75 .B \-S\fR, \fB\-\-strip\-all
  76 Do not copy relocation and symbol information from the source file.
  77 .TP
  78 .B \-g\fR, \fB\-\-strip\-debug
  79 Do not copy debugging symbols from the source file.
  80 .TP
  81 .B \-x\fR, \fB \-\-discard\-all
  82 Do not copy non-global symbols from the source file.
  83 .TP
  84 .B \-X\fR, \fB\-\-discard\-locals
  85 Do not copy compiler-generated local symbols. (These usually start
  86 with "L" or ".").
  87 .TP
  88 .B \-v\fR, \fB\-\-verbose
  89 Verbose output: list all object files modified.  In the case of
  90 archives, "\fBobjcopy \-V\fR" lists all members of the archive.
  91 .TP
  92 .B \-V\fR, \fB\-\-version
  93 Show the version number of
  94 .B objcopy
  95 and exit.
  96 .TP
  97 .B \-\-help
  98 Show a summary of the options to
  99 .B objcopy
 100 and exit.
