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 pro-
cessed. 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 confi-
guration 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 gzip
head join jsh ksh ln
ls mdb mkdir mkfifo more
mv nawk page paste pathchck
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 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:
install mkfile mknod mvdir swap
See the USAGE section of the swap(1M) manual page for limi-
tations 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

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:

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 corruption when it encounters a large file. A util-
ity 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:
