+erase-file File_ID [fill-byte]
+
+This command erases the specified EF by overwriting its content with the
+specified fill byte, which defaults to 0xFF if the second argument is omitted.
+All 3 EF types (transparent, linear fixed and cyclic) are supported: for
+transparent EFs fc-simtool issues as many UPDATE BINARY commands as needed to
+overwrite the whole file, whereas for record-based EFs every record is
+overwritten with UPDATE RECORD.
