Name
     largefile - large file status of utilities

Description
     A large file is a regular file whose size is greater than or
     equal  to  2  Gbyte ( 2^31 bytes). A small file is a regular
     file whose size is less than 2 Gbyte.

  Large file aware utilities
     A utility is called large file aware if it can process large
     files  in  the same manner as it does small files. A utility
     that is large file aware is able to handle  large  files  as
     input and generate as output large files that are being pro-
     cessed. The exception is where additional files are used  as
     system configuration files or support files that can augment
     the processing. For example, the file utility  supports  the
     -m  option for an alternative "magic" file and the -f option
     for a support file that can contain a list of file names. It
     is  unspecified  whether  a utility that is large file aware
     will accept configuration or support files  that  are  large
     files.  If a large file aware utility does not accept confi-
     guration or support files that  are  large  files,  it  will
     cause  no  data  loss  or  corruption upon encountering such
     files and will return an appropriate error.


     The following /usr/bin utilities are large file aware:

     The /usr/bin/cpio and /usr/bin/pax utilities are large  file
     aware,  but cannot archive a file whose size exceeds 8 Gbyte
     - 1 byte.


     The /usr/bin/truss utilities has been  modified  to  read  a
     dump  file  and display information relevant to large files,
     such as offsets.

  nfs file systems
     The following utilities are large file aware  for  nfs  file
     systems:
     tab();    lw(2.75i)    lw(2.75i)     lw(2.75i)     lw(2.75i)
     /usr/lib/autofs/automountd/usr/sbin/mount
     /usr/lib/nfs/rquotad


  ufs file systems
     The following /usr/bin utility is large file aware  for  ufs
     file systems:


     df


     The following /usr/lib/nfs utility is large file  aware  for
     ufs file systems:


     rquotad


     The following /usr/xpg4/bin utility is large file aware  for
     ufs file systems:

  Large file safe utilities
     A utility is called large file safe if  it  causes  no  data
     loss  or corruption when it encounters a large file. A util-
     ity that is large file safe is unable to process properly  a
     large file, but returns an appropriate error.


     The following /usr/bin utilities are large file safe:



     tab();  lw(1.36i)  lw(1.04i)  lw(1.21i)  lw(1.11i)  lw(.78i)
     lw(1.36i)    lw(1.04i)    lw(1.21i)    lw(1.11i)    lw(.78i)
