largefile - large file status of utilities

DESCRIPTION

On a 32-bit system, a large file is a regular file whose size is greater than or equal to 2 Gbyte (21 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 large files as output.

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
mkdir        mkfifo     more       mv      nawk
page         paste      pathchk    pg      rcp
remsh        rksh       rm         rmdir   rsh
sed          sh         sort       split   sum
tail         tee        test       touch   tr
uncompress   uudecode   uuencode   wc      zcat

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

install   mkfile   mknod   mvdir

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

Mail   chown   from   ln      lpr
ls     sed     sum    touch

The /usr/bin/cpio, /usr/bin/pax, and /usr/bin/tar 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 stytems

The following utilities are large file aware for nfs file systems:

: /usr/lib/autofs/automountd /usr/sbin/mount

ufs file stytems

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

: lpfilter lpforms swap

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

: sendmail
