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 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 limitations of swap on block devices greater than 2 Gbyte on a 32-bit operating sys- tem. 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 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: ed vi view The following /usr/xpg6/bin utility is large file safe: ed The following /usr/sbin utilities are large file safe: lpfilter lpforms The following /usr/ucb utilities are large file safe: Mail lpr The following /usr/lib utility is large file safe: sendmail SEE ALSO
