A \fIsmall file\fR is a regular file whose size is less 15 than 2 Gbyte. 16 .SS "Large file aware utilities" 17 .sp 18 .LP 19 A utility is called \fIlarge file aware\fR if it can process large files in the 20 same manner as it does small files. A utility that is large file aware is able 21 to handle large files as input and generate as output large files that are 22 being processed. The exception is where additional files are used as system 23 configuration files or support files that can augment the processing. For 24 example, the \fBfile\fR utility supports the \fB-m\fR option for an alternative 25 "magic" file and the \fB-f\fR option for a support file that can contain a list 26 of file names. It is unspecified whether a utility that is large file aware 27 will accept configuration or support files that are large files. If a large 28 file aware utility does not accept configuration or support files that are 29 large files, it will cause no data loss or corruption upon encountering such 30 files and will return an appropriate error. 31 .sp 32 .LP 33 The following \fB/usr/bin\fR utilities are large file aware: 34 .sp 35 36 .sp 37 .TS 38 l l l l l 39 l l l l l . 40 \fBadb\fR \fBaliasadm\fR \fBawk\fR \fBbdiff\fR \fBcat\fR 41 \fBchgrp\fR \fBchmod\fR \fBchown\fR \fBcksum\fR \fBcmp\fR 42 \fBcompress\fR \fBcp\fR \fBcsh\fR \fBcsplit\fR \fBcut\fR 43 \fBdd\fR \fBdircmp\fR \fBdu\fR \fBegrep\fR \fBfgrep\fR 44 \fBfile\fR \fBfind\fR \fBftp\fR \fBgetconf\fR \fBgrep\fR 45 \fBgzip\fR \fBhead\fR \fBjoin\fR \fBjsh\fR \fBksh\fR 46 \fBksh93\fR \fBln\fR \fBls\fR \fBmailcompat\fR \fBmailstats\fR 47 \fBmdb\fR \fBmkdir\fR \fBmkfifo\fR \fBmore\fR \fBmv\fR 48 \fBnawk\fR \fBpage\fR \fBpaste\fR \fBpathchck\fR \fBpg\fR 49 \fBpraliases\fR \fBrcp\fR \fBremsh\fR \fBrksh\fR \fBrksh93\fR 50 \fBrm\fR \fBrmdir\fR \fBrsh\fR \fBsed\fR \fBsh\fR 51 \fBsort\fR \fBsplit\fR \fBsum\fR \fBtail\fR \fBtar\fR 52 \fBtee\fR \fBtest\fR \fBtouch\fR \fBtr\fR \fBuncompress\fR 53 \fBuudcode\fR \fBuuencode\fR \fBvacation\fR \fBwc\fR \fBzcat\fR 54 .TE 55 56 .sp 57 .LP 58 The following \fB/usr/xpg4/bin\fR utilities are large file aware: 59 .sp 60 61 .sp 62 .TS 63 l l l l l 64 l l l l l . 65 \fBawk\fR \fBcp\fR \fBchgrp\fR \fBchown\fR \fBdu\fR 66 \fBegrep\fR \fBfgrep\fR \fBfile\fR \fBgrep\fR \fBln\fR 67 \fBls\fR \fBmore\fR \fBmv\fR \fBrm\fR \fBsed\fR 68 \fBsh\fR sort tail tr 69 .TE 70 71 .sp 72 .LP 73 The following \fB/usr/xpg6/bin\fR utilities are large file aware: 74 .sp 75 76 .sp 77 .TS 78 l l l l l . 79 \fBgetconf\fR \fBls\fR \fBtr\fR 80 .TE 81 82 .sp 83 .LP 84 The following \fB/usr/sbin\fR utilities are large file aware: 85 .sp 86 87 .sp 88 .TS 89 l l l l l 90 l l l l l . 91 \fBeditmap\fR \fBinstall\fR \fBmakemap\fR \fBmkfile\fR \fBmknod\fR 92 \fBmvdir\fR \fBswap\fR 93 .TE 94 95 .sp 96 .LP 97 The following \fB/usr/lib\fR utilities are large file aware: 98 .sp 99 100 .sp 101 .TS 102 l l l l l . 103 \fBmail.local\fR \fBsendmail\fR \fBsmrsh\fR 104 .TE 105 106 .sp 107 .LP 108 See the USAGE section of the \fBswap\fR(1M) manual page for limitations of 109 \fBswap\fR on block devices greater than 2 Gbyte on a 32-bit operating system. 110 .sp 111 .LP 112 The following \fB/usr/ucb\fR utilities are large file aware: 113 .sp 114 115 .sp 116 .TS 117 l l l l l 118 l l l l l . 119 \fBchown\fR \fBfrom\fR \fBln\fR \fBls\fR \fBsed\fR 120 \fBsum\fR \fBtouch\fR 121 .TE 122 123 .sp 124 .LP 125 The \fB/usr/bin/cpio\fR and \fB/usr/bin/pax\fR utilities are large file aware, 126 but cannot archive a file whose size exceeds 8 Gbyte - 1 byte. 127 .sp 128 .LP 129 The \fB/usr/bin/truss\fR utilities has been modified to read a dump file and 130 display information relevant to large files, such as offsets. 131 .SS "cachefs file systems" 132 .sp 133 .LP 134 The following \fB/usr/bin\fR utilities are large file aware for \fBcachefs\fR 135 file systems: 136 .sp 137 138 .sp 139 .TS 140 l l l l . 141 \fBcachefspack\fR \fBcachefsstat\fR 142 .TE 143 144 .sp 145 .LP 146 The following \fB/usr/sbin\fR utilities are large file aware for \fBcachefs\fR 147 file systems: 148 .sp 149 150 .sp 151 .TS 152 l l l l 153 l l l l . 154 \fBcachefslog\fR \fBcachefswssize\fR \fBcfsadmin\fR \fBfsck\fR 155 \fBmount\fR \fBumount\fR 156 .TE 157 158 .SS "nfs file systems" 159 .sp 160 .LP 161 The following utilities are large file aware for \fBnfs\fR file systems: 162 .sp 163 164 .sp 165 .TS 166 l l 167 l l . 168 \fB/usr/lib/autofs/automountd\fR \fB/usr/sbin/mount\fR 169 \fB/usr/lib/nfs/rquotad\fR 170 .TE 171 172 .SS "ufs file systems" 173 .sp 174 .LP 175 The following \fB/usr/bin\fR utility is large file aware for \fBufs\fR file 176 systems: 177 .sp 178 .LP 179 \fBdf\fR 180 .sp 181 .LP 182 The following \fB/usr/lib/nfs\fR utility is large file aware for \fBufs\fR file 183 systems: 184 .sp 185 .LP 186 \fBrquotad\fR 187 .sp 188 .LP 189 The following \fB/usr/xpg4/bin\fR utility is large file aware for \fBufs\fR 190 file systems: 191 .sp 192 .LP 193 \fBdf\fR 194 .sp 195 .LP 196 The following \fB/usr/sbin\fR utilities are large file aware for \fBufs\fR file 197 systems: 198 .sp 199 200 .sp 201 .TS 202 l l l l l 203 l l l l l . 204 \fBclri\fR \fBdcopy\fR \fBedquota\fR \fBff\fR \fBfsck\fR 205 \fBfsdb\fR \fBfsirand\fR \fBfstyp\fR \fBlabelit\fR \fBlockfs\fR 206 \fBmkfs\fR \fBmount\fR \fBncheck\fR \fBnewfs\fR \fBquot\fR 207 \fBquota\fR \fBquotacheck\fR \fBquotaoff\fR \fBquotaon\fR \fBrepquota\fR 208 \fBtunefs\fR \fBufsdump\fR \fBufsrestore\fR \fBumount\fR 209 .TE 210 211 .SS "Large file safe utilities" 212 .sp 213 .LP 214 A utility is called \fBlarge file safe\fR if it causes no data loss or 215 corruption when it encounters a large file.
