largefile - large file status of utilities
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:

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
