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 ( 231 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:

adbawkbdiffcatchgrp
chmodchowncksumcmpcompress
cpcshcsplitcutdd
dircmpduegrepfgrepfile
findftpgetconfgrephead
joinjshkshlnls
mdbmkdirmkfifomoremv

wczcat   

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

awkcpduegrepfgrep
greplnlsmoremv
rmsedshsorttail
tr    

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

installmkfilemknodmvdirswap

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 system.

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

chownfromlnlssed
sumtouch   

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:

cachefspackcachefsstat  

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

cachefslogcachefswssizecfsadminfsck
mountumount  

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 systems:

df

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

tunefsufsdumpufsrestoreumount 

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:

audioconvertaudioplayaudiorecordcommdiff
diff3diffmkedlpmail
mailcompatmailstatsmailxpackpcat
redrmailsdiffunpackvi
view    

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

edviview  

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

lpfilter lpforms   

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

Maillpr   

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