NAME

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 31 Gbyte (2 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

and Macros..largefile ( 5 ) 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
