DRUTIL(1) BSD General Commands Manual DRUTIL(1)NAMEdrutil — interact with CD/DVD burners
SYNOPSISdrutil verb [options]
DESCRIPTIONdrutil uses the DiscRecording framework to interact with attached burning
devices. Common verbs include burn, erase, eject, help, info, list,
status, and tray.
The rest of the verbs are: bulkerase, cdtext, discinfo, dumpiso, dumpudf,
filename, getconfig, poll, size, subchannel, trackinfo, and version.
VERBS
Each verb is listed with its description and individual arguments. Drive
selection arguments must appear before individual arguments. Drive
selection and argument descriptions can be found after the verb descrip‐
tions in the Drive Selection Criteria section.
-drivedrive(s)
Lets you specify a drive or drives, per the output of list,
for those verbs that can operate on one or more drives. See
the Drive Selection Criterion section for more info.
help verb
Display the usage information for the specified verb.
atip
Displays the Absolute Time in Pre-Groove (ATIP) for inserted
CD-R/RW media.
bulkerase type
Starts bulk erase mode, in which the drive will continually
erase inserted -RW media, eject it, and prompt for another
disc until terminated.
Types of erase:
quick Performs a quick erase, doing the minimal amount of
work to make the disc appear blank. This operation
typically takes only a minute or two.
full Performs a complete erase, erasing every block on the
disk. This operation is slow (on the order of 30 min‐
utes) to complete.
burn options path
Burns a valid directory or image file to disc. The default is
to burn the specified directory to a new filesystem. The
-audio option creates an audio CD (redbook) in which any valid
QuickTime audio file present in the path is converted to a
track (in alphabetical order). If a file is specified (valid
image files only: .dmg, .iso, .cue/bin, and .toc) the contents
of the image file are burned. Pre-burn and post-burn options,
and filesystem exclusions can be specificed for enhanced func‐
tionality. Last option takes precedence. Invalid commands are
ignored.
path A valid path to a directory or file.
options Specify an arbitrary valid burn option(s): -test,
-appendable, -erase, -mount, -noverify, -nohfsplus,
-noiso9660, -nojoliet, -noudf, -nofs, -audio, -speed,
-pregap. Or specify a default burn option: -notest,
-noappendable, -noerase, -allfs, -hfsplus, -iso9660,
-joliet, -udf, -data, -eject, -verify.
cdtext
Reads and displays any CD-Text information reported by the
drive. The drive must contain an audio CD, and be capable of
reading CD-Text.
discinfo [-xml]
Displays detailed information about present media.
From the MMC command of the same name.
dumpiso device block [format]
Tool to inspect and interpret ISO-9660 and Joliet structures
on the media.
device Disk node, e.g. /dev/disk1, /dev/disk1s1,
/dev/rdisk1.
block Block number to dump (in decimal or 0x hex notation).
Blocks are assumed to be 2048-byte blocks.
format How to interpret the block. If format is not speci‐
fied, dumpiso will attempt to guess. If present,
this argument should be one of the following: None,
Boot, BootCat, PVD, SVD, VPD, VDST, MPath, LPath,
Dir, HFSPlusVH.
dumpudf device block
Tool to inspect and interpret UDF structures on the media.
device Disk node, e.g. /dev/disk1, /dev/disk1s1,
/dev/rdisk1.
block Block number to dump (in decimal or 0x hex notation).
Blocks are assumed to be 2048-byte blocks.
eject
Synonym for drutil tray eject.
erase type
Erases -RW media in the drive(s) and ejects it.
Types of erase:
quick Performs a quick erase, doing the minimal amount of
work to make the disc appear blank. This operation
typically takes only a minute or two.
full Performs a complete erase, erasing every block on the
disk. This operation is slow (on the order of 30 min‐
utes) to complete.
filename name
Shows how the specified filename will be modified to comply
with the naming rules of the filesystems that DiscRecording
generates.
getconfig type
Displays device feature and profile list.
Types of config information:
current Displays current features and profiles for a drive.
supported Displays all supported features and profiles for a
drive.
info [-xml]
Displays various pieces of information for each drive, includ‐
ing how it's connected to the computer and a summary of capa‐
bilities.
list [-xml]
Lists all burning devices connected to the machine.
poll
Displays device and media notifications until terminated.
size options path
Estimates the size of a valid directory or image file (in
blocks). The default is to estimate the size of the specified
path as a hybrid filesystem. The -audio option calculates the
contents of the directory as an audio CD (redbook) (for appli‐
cable files). If a file is specified (valid image files only:
.dmg, .iso, .cue/bin, and .toc) the contents of the image file
will be calculated. Filesystem exclusions can be specificed
for enhanced functionality. Calculated size will be compared
against blank media that is found unless the -nodrive argument
is specified. Last option takes precedence. Invalid commands
are ignored.
path A valid path to a directory or file.
options Specify an arbitrary valid burn option(s): -nodrive,
-nohfsplus, -noiso9660, -nojoliet, -noudf, -nofs,
-audio, -pregap. Or specify a default burn option:
-allfs, -hfsplus, -iso9660, -joliet, -udf, -data.
status [-xml]
Displays detailed media-specific information.
subchannel
Displays information from the subchannels on CD media. This
prints the MCN (media catalog number) for the disc, and the
ISRC (international standard recording code) for all tracks.
This command only works when CD media is present.
From the MMC command of the same name.
toc
Displays table of contents (TOC) of inserted media.
trackinfo [-xml]
Displays detailed information about all tracks present on the
media.
From the MMC command of the same name.
tray command
Performs a tray/media related command. Note that some drives
do not have trays, and some have trays but may lack motorized
eject or inject capability.
Tray commands:
open Opens a drive's tray, if no media is present and the
drive has a tray capable of motorized eject.
close Closes a drive's tray, if the drive has a tray capa‐
ble of motorized inject.
eject Ejects media from the drive, if the drive has a tray
capable of motorized eject. If no media is present,
this is equivalent to open. If media is present and
can be unmounted, it will be unmounted and then
ejected. If media is present but cannot be
unmounted, the eject will fail.
version
Displays operating system and DiscRecording framework version
numbers.
OPTIONS-xml
When specified (valid options only: discinfo, info, list,
status, and trackinfo) the output for the specified verb will
be shown in xml format.
DRIVE SELECTION CRITERIA
Some functions of drutil operate on a specific drive. Since any number of
drives may be available, and they may come and go at any time, the device
selection arguments provide a method for selecting among them.
The candidate list starts out as a list of all attached drives. One or
more arguments of the form -drivedrive(s) may be specified. Each argu‐
ment has the effect of narrowing the candidate list, depending on what
drive(s) is. It may be:
· A positive decimal number, assumed to be a 1-based index
into the candidate list. The candidate list is trimmed to
just that device.
· One of the following keywords: internal, external, usb,
firewire, atapi, scsi. The candidate list is trimmed to
devices which match the specified location / bus. Case is
ignored in this comparison.
· Any other string, assumed to be a vendor/product name. The
candidate list is trimmed to devices whose vendor or product
strings exactly match the argument. Case (but not white‐
space) is ignored in this comparison.
Multiple -drive arguments may be specified; each argument narrows the
candidate list further. After all the -drive arguments have been pro‐
cessed, the candidate list is considered. If it contains exactly one
item, that drive is used. If it contains zero items, drutil prints an
error message and exits. If it contains more than one item, the selected
function is executed on all drives remaining in the list.
EXAMPLES
Simple verbs with no drive commands
