  12 .LP
  13 A \fIlarge file\fR is a regular file whose size is greater than or equal to 2
  14 Gbyte ( 2^31 bytes). A \fIsmall file\fR is a regular file whose size is less
  15 than 2 Gbyte.
  16 .SS "Large file aware utilities"
  17 .sp
  18 .LP
  19 A utility is called \fIlarge file aware\fR if it can process large files in the
  20 same manner as it does small files. A utility that is large file aware is able
  21 to handle large files as input and generate as output large files that are
  22 being processed. The exception is where additional files  are used as system
  23 configuration files or support files that can augment the processing. For
  24 example, the \fBfile\fR utility supports the \fB-m\fR option for an alternative
  25 "magic" file and the \fB-f\fR option for a support file that can contain a list
  26 of file names. It is unspecified whether a utility that is large file aware
  27 will accept configuration or support files that are large files. If a large
  28 file aware utility does not accept configuration or support files that are
  29 large files, it will cause no data loss or corruption upon encountering such
  30 files and will return an appropriate error.
