The disk image will 71 occupy the least space possible for its format, or the least space that the 72 authors have been able to figure out how to achieve. 73 74 =head1 OPTIONS 75 76 =over 5 77 78 ==item B<--source> I<source-folder> 79 80 Identifies the directory that will be packaged up. This directory is not 81 touched, a copy will be made in a temporary directory for staging purposes. 82 See B<--tempdir>. 83 84 ==item B<--target> I<target-image> 85 86 The disk image to create. If it exists and is not in use, it will be 87 overwritten. If I<target-image> already contains a suitable extension, 88 it will be used unmodified. If no extension is present, or the extension 89 is incorrect for the selected format, the proper extension will be added. 90 See B<--format>. 91 92 ==item B<--format> I<format> 93 94 The format to create the disk image in. Valid values for I<format> are: 95 - UDZO - zlib-compressed, read-only; extension I<.dmg> 96 - UDBZ - bzip2-compressed, read-only; extension I<.dmg>; 97 create and use on 10.4 ("Tiger") and later only 98 - UDRO - uncompressed, read-only; extension I<.dmg> 99 - UDRW - uncompressed, read-write; extension I<.dmg> 100 - UDSP - uncompressed, read-write, sparse; extension I<.sparseimage> 101 102 UDZO is the default format. 103 104 See L<hdiutil(1)> for a description of these formats. 105 106 =item B<--volname> I<volume-name> 107 108 The name of the volume in the disk image. If not specified, I<volume-name> 109 defaults to the name of the source directory from B<--source>. 110 111 =item B<--tempdir> I<temp-dir> 112 113 A temporary directory to stage intermediate files in. I<temp-dir> must 114 have enough space available to accommodate twice the size of the files 115 being packaged. If not specified, defaults to the same directory that 116 the I<target-image> is to be placed in. B<pkg-dmg> will remove any 117 temporary files it places in I<temp-dir>. 118 119 =item B<--mkdir> I<directory> 120 121 Specifies a directory that should be created in the disk image. 122 I<directory> and any ancestor directories will be created. This is 123 useful in conjunction with B<--copy>, when copying files to directories 124 that may not exist in I<source-folder>. B<--mkdir> may appear multiple 125 times. 126 127 =item B<--copy> I<source>[:I<dest>] 128 129 Additional files to copy into the disk image. If I<dest> is 130 specified, I<source> is copied to the location I<dest> identifies, 131 otherwise, I<source> is copied to the root of the new volume. B<--copy> 132 provides a way to package up a I<source-folder> by adding files to it 133 without modifying the original I<source-folder>. B<--copy> may appear 134 multiple times. 135 136 This option is useful for adding .DS_Store files and window backgrounds 137 to disk images. 138 139 =item B<--symlink> I<source>[:I<dest>] 140 141 Like B<--copy>, but allows symlinks to point out of the volume. Empty symlink 142 destinations are interpreted as "like the source path, but inside the dmg" 143 144 This option is useful for adding symlinks to external resources, 145 e.g. to /Applications. 146 147 =item B<--license> I<file> 148 149 A plain text file containing a license agreement to be displayed before 150 the disk image is mounted. English is the only supported language. To 151 include license agreements in other languages, in multiple languages, 152 or to use formatted text, prepare a resource and use L<--resource>. 153 154 =item B<--resource> I<file> 155 156 A resource file to merge into I<target-image>. If I<format> is UDZO, UDBZ, 157 or UDRO, the disk image will be flattened to a single-fork file that contains 158 the resource but may be freely transferred without any special encodings. 159 I<file> must be in a format suitable for L<Rez(1)>. See L<Rez(1)> for a 160 description of the format, and L<hdiutil(1)> for a discussion on flattened 161 disk images. B<--resource> may appear multiple times. 162 163 This option is useful for adding license agreements and other messages 164 to disk images. 165 166 =item B<--icon> I<icns-file> 167 168 Specifies an I<icns> file that will be used as the icon for the root of 169 the volume. This file will be copied to the new volume and the custom 170 icon attribute will be set on the root folder. 171 172 =item B<--attribute> I<a>:I<file>[:I<file>...] 173 174 Sets the attributes of I<file> to the attribute list in I<a>. See 175 L<SetFile(1)> 176 177 =item B<--idme> 178 179 Enable IDME to make the disk image "Internet-enabled." The first time 180 the image is mounted, if IDME processing is enabled on the system, the 181 contents of the image will be copied out of the image and the image will 182 be placed in the trash with IDME disabled. 183 184 =item B<--sourcefile> 185 186 If this option is present, I<source-folder> is treated as a file, and is 187 placed as a file within the volume's root folder. Without this option, 188 I<source-folder> is treated as the volume root itself. 189 190 =item B<--verbosity> I<level> 191 192 Adjusts the level of loudness of B<pkg-dmg>. The possible values for 193 I<level> are: 194 0 - Only error messages are displayed. 195 1 - Print error messages and command invocations. 196 2 - Print everything, including command output. 197 198 The default I<level> is 2. 199 200 =item B<--dry-run> 201 202 When specified, the commands that would be executed are printed, without 203 actually executing them. When commands depend on the output of previous 204 commands, dummy values are displayed. 205 206 =back 207 208 =head1 NON-OPTIONS 209 210 =over 5 211 212 =item 213 214 Resource forks aren't copied. 215 216 =item 217 218 The root folder of the created volume is designated as the folder 219 to open when the volume is mounted. See L<bless(8)>. 220 221 =item 222 223 All files in the volume are set to be world-readable, only writable 224 by the owner, and world-executable when appropriate. All other 225 permissions bits are cleared. 226 227 =item 228 229 When possible, disk images are created without any partition tables. This 230 is what L<hdiutil(1)> refers to as I<-layout NONE>, and saves a handful of 231 kilobytes. The alternative, I<SPUD>, contains a partition table that 232 is not terribly handy on disk images that are not intended to represent any 233 physical disk. 234 235 =item 236 237 Read-write images are created with journaling off. Any read-write image 238 created by this tool is expected to be transient, and the goal of this tool 239 is to create images which consume a minimum of space. 240 241 =back 242 243 =head1 EXAMPLE 244 245 pkg-dmg --source /Applications/DeerPark.app --target ~/DeerPark.dmg 246 --sourcefile --volname DeerPark --icon ~/DeerPark.icns 247 --mkdir /.background 248 --copy DeerParkBackground.png:/.background/background.png 249 --copy DeerParkDSStore:/.DS_Store 250 --symlink /Applications:"/Drag to here" 251 252 =head1 REQUIREMENTS 253 254 I<pkg-dmg> has been tested with Mac OS X releases 10.2 ("Jaguar") 255 through 10.4 ("Tiger").
