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 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 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:
| 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 | |
| mailcompat | mailstats | mailx | pack | pcat |
| red | rmail | sdiff | unpack | vi |
