  37 GNU
  38 .B strip
  39 discards all symbols from the object files

  47 rather than writing modified copies under different names.

  51 .B "\-F \fIbfdname"
  52 .TP
  53 .B "\-\-target=\fIbfdname"
  54 Treat the original \fIobjfile\fP as a file with the object
  55 code format \fIbfdname\fP, and rewrite it in the same format.
  56
  57 .TP
  58 .B \-\-help
  59 Show a summary of the options to
  60 .B strip
  61 and exit.
  62
  63 .TP
  64 .B "\-I \fIbfdname
  65 .TP
  66 .B "\-\-input\-target=\fIbfdname"
  67 Treat the original \fIobjfile\fP as a file with the object
  68 code format \fIbfdname\fP.
  69
  70 .TP
  71 .B "\-O \fIbfdname\fP"
  72 .TP
  73 .B "\-\-output\-target=\fIbfdname"

  77 .B "\-R \fIsectionname\fP"
  78 .TP
  79 .B "\-\-remove\-section=\fIsectionname"
  80 Remove the named section from the file.  This option may be given more

  82 object file unusable.

 108 options.
 109
