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 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 uudecode 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(8) manual page for limitations 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.
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 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
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:
