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 processed. 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 configu-
       ration 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:

       adb	     aliasadm	   awk		 bdiff	       cat

       uudcode	     uuencode	   vacation	 wc	       zcat

       The following /usr/xpg4/bin utilities are large file aware:

       awk	     cp 	   chgrp	 chown	       du
       egrep	     fgrep	   file 	 grep	       ln
       ls	     more	   mv		 rm	       sed
       sh	     sort	   tail 	 tr

       The following /usr/xpg6/bin utilities are large file aware:

       getconf	     ls 	   tr

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

       editmap	     install	   makemap	 mkfile        mknode
       mvdir	     swap

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

       mail.local    sendmail	   smrsh

       See the USAGE section of the swap(1M) manual page for limitations of swap on block devices
       greater than 2 Gbyte on a 32-bit operating system.

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

       chown	     from	   ln		 ls	       sed
       sum	     touch

       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.

   cachefs file systems
       The following /usr/bin utilities are large file aware for cachefs file systems:

       cachefspack	cachefsstat

       The following /usr/sbin utilities are large file aware for cachefs file systems:

       cachefslog	cachefswssize	 cfsadmin	 fsck
       mount		umount

   nfs file systems
       The following utilities are large file aware for nfs file systems:

       /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:

       df

       mkfs	     mount	   ncheck	 newfs	       quot
       quota	     quotacheck    quotaoff	 quotaon       repquota
       tunefs	     ufsdump	   ufsrestore	 umount

   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 utility 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:

       audioconvert	audioplay    audiorecord    comm	  diff
       diff3		diffmk	     ed 	    lp		  mail

       red		rmail	     sdiff	    unpack	  vi
       view

       The following /usr/xpg4/bin utilities are large file safe:

       ed	     vi 	   view

       The following /usr/xpg6/bin utility is large file safe:

       ed

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

       lpfilter      lpforms

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