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	     awk	   bdiff	 cat	       chgrp
       chmod	     chown	   cksum	 cmp	       compress
       cp	     csh	   csplit	 cut	       dd
       dircmp	     du		   egrep	 fgrep	       file
       find	     ftp	   getconf	 grep	       head
       join	     jsh	   ksh		 ln	       ls
       mdb	     mkdir	   mkfifo	 more	       mv
       nawk	     page	   paste	 pathchk       pg
       rcp	     remsh	   rksh		 rm	       rmdir
       rsh	     sed	   sh		 sort	       split
       sum	     tail	   tar		 tee	       test
       touch	     tr		   uncompress	 uudecode      uuencode
       wc	     zcat

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

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

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

       install	     mkfile	   mknod	 mvdir	       swap

       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/sbin/crash and /usr/bin/truss utilities	have 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

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

	      df

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

	      df

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

       clri	     dcopy	   edquota	 ff	       fsck
       fsdb	     fsirand	   fstyp	 labelit       lockfs
       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 cor-
       ruption when it encounters a large file.	A utility that is  large  file
       safe  is	unable to process properly a large file, but returns an	appro-
       priate 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/sbin utilities are large file	safe:

       lpfilter	     lpforms

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

       Mail	     lpr

       The following /usr/lib utility is large file safe:

	      sendmail
