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 configuration 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

       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

       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  sys-
       tem.

       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

       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
       mailcompat	mailstats    mailx	    pack	  pcat
       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:

       Mail	     lpr
