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
chgrp chmod chown cksum cmp
compress cp csh csplit cut
dd dircmp du egrep fgrep
file find ftp getconf grep
gzip head join jsh ksh
ksh93 ln ls mailcompat mailstats
mdb mkdir mkfifo more mv
nawk page paste pathchck pg
praliases rcp remsh rksh rksh93
rm rmdir rsh sed sh
sort split sum tail tar
tee test touch tr uncompress
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 mknod
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 sys‐
tems:
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:

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

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/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
