@c man .SH DESCRIPTION
|
|
@c man .PP
|
|
@command{xorriso-dd-target}
|
|
evaluates block devices of the Linux kernel whether they are suitable targets
|
|
for a disk image file and optionally copies the image file to one of them.
|
|
@*
|
|
It is specialized on the device names of the @strong{Linux kernel} and uses the
|
|
capabilities of util-linux program @strong{lsblk}.
|
|
Therefore it refuses to run on non-Linux kernels.
|
|
@*
|
|
@sp 1
|
|
@c man .PP
|
|
The main purpose of xorriso-dd-target is to inspect the device files
|
|
of disk-like storage media and to judge whether they look like removable
|
|
devices with disposable content.
|
|
@*
|
|
If a single plausible candidate is detected, then the program is willing to
|
|
copy a disk image file onto it. This will overwrite or make inaccessible the
|
|
previous partition table and all previous data content of the target device.
|
|
@*
|
|
@strong{Superuser power} is often needed for filesystem type identification,
|
|
for possible unmounting, and for possible image writing.
|
|
Option @strong{-with_sudo} offers a way to gain this power only for those
|
|
tasks and to run the program elsewise with a normal user's power.
|
|
@*
|
|
If a particular disk image file is intended as copy source, then
|
|
its path should be given by option -image_file, so that its size can be used
|
|
as decision criterion.

@c man \fBList plain device names:\fR

@c man .br
|
|
@cindex Use case, list advisable device names
|
|
The most simple and most boring use case is a program run without device names
|
|
and without options -list_all, -plug_test, -DO_WRITE, -dummy_force.
|
|
It prints on standard output (stdout) only the names of advisable devices
|
|
without "/dev/" prefix. One name per line and without any reasoning text.
|
|
@*
|
|
The possible sudo password prompt, the message line about sudo, and the
|
|
empty line after it do not go to stdout.
|
|
@*
|
|
Example:
|
|
@*
|
|
$ xorriso-dd-target -with_sudo
|
|
@*
|
|
Testing sudo to possibly get password prompting done now:
|
|
@*
|
|
[sudo] password for thomas:
|
|
@*
|
|
sudo /bin/lsblk seems ok.

|
|
@c man \fBList all devices with reasoning:\fR
|
|
@c man .br
|
|
@cindex Use case, list all devices with reasoning
|
|
For the more curious user, there is option @strong{-list_all} which prints
|
|
the evaluation of each disk-like device that is listed by program lsblk.
|
|
Optical drives, floppy disks, RAM block devices, loop devices are excluded,
|
|
though.
|
|
@*
|
|
Each device is shown by one line of the form
|
|
@*
|
|
name : advice : reasoning : info
|
|
@*
|
|
@strong{name} is the device name without "/dev/" prefix.
|
|
@*
|
|
@strong{advice} is either "YES" or "NO". "YES" indicates that the device
|
|
appears to be pluggable disk-like, not used as system disk or sincere data
|
|
storage, and - if tested - of sufficient or plausible size.
|
|
@*
|
|
@strong{reasoning} is a blank separated list of words with either suffix '+'
|
|
for an inviting device property or '-' for a prohibitive property. Normally
|
|
a single '-' reason disqualifies the device from being advisable. Only if
|
|
option -look_for_iso is given, a reason "has_XYZ-" can be overridden by
|
|
the presence of an ISO 9660 filesystem on the device.
|
|
@*
|
|
@strong{info} is composed from VENDOR and MODEL as told by lsblk.
|
|
@*
|
|
Option @strong{-list_long} causes with each line an additional listing of
|
|
the information provided by lsblk which led to the shown reasons.
|
|
@*
|
|
Example:
|
|
@*
|
|
$ xorriso-dd-target -with_sudo -list_all
|
|
@*

|
@cindex Use case, evaluate particular given devices
|
|
If @strong{device names} are given instead of option -list_all, then only
|
|
these devices are inspected. Their result gets listed without the ": info"
|
|
part, unless option @strong{-with_vendor_model} is given.
|
|
@*
|
|
Device names must not begin by '-' and must be single words composed of
|
|
the characters [A-za-z0-9_/-]. They should not contain '/'. E.g. 'sdc' is
|
|
valid, '/dev/sdc' is not valid.
|
|
@*
|
|
If one of the given device names gets not advised, the exit value is 1.
|
|
@*
|
|
It makes few sense to give device names which are not listed by -list_all.
|
|
@*

@cindex Use case, detect intended device by plugging
|
|
Option @strong{-plug_test} triggers an interactive method to unambiguously
|
|
determine the intended target device candidate. It consists of 2 or 3 steps.
|
|
@*
|
|
@strong{Step 1} is to have the intended storage device @strong{unplugged} and
|
|
to confirm this by pressing the Enter key at the program's prompt. The program
|
|
will then assess the list of not wanted devices.
|
|
@*
|
|
@strong{Step 2} is to @strong{plug in} the intended storage device and to
|
|
confirm this by pressing the Enter key a second time. The program will wait
|
|
up to 10 seconds for a disk-like storage device which is not in the list of
|
|
not wanted devices.
|
|
The user may wait with key pressing until the device blinking looks like it
|
|
is ready.
|
|
@*
|
|
Only if a single new device is found, the program will go on as if a single
|
|
device name was given. Option -list_all and any device names given as arguments
|
|
will be ignored.
|
|
@*
|
|
@strong{Step 3} happens only if options -DO_WRITE or -dummy_force are given.
|
|
The program asks for a final input of the word 'yes' before real or simulated
|
|
writing begins.
|
|
@*
|
|
Example:
|
|
@*
|
|
$ xorriso-dd-target -with_sudo -plug_test

Step 1:
|
|
@*
|
|
Please make sure that the desired target device is plugged _out_ now.
|
|
@*
|
|
If it is currently plugged in, make sure to unmount all its fileystems
|
|
@*
|
|
and then unplug it.
|
|
@*
|
|
Press the Enter key when ready.

|
Only if option @strong{-DO_WRITE} is given and -list_all is not, and if exactly

one advisable device is listed, it really gets overwritten by the file content
|
|
of the given -image_file. In this case the exit value is zero if writing

succeeded, non-zero else.
|

@*
|

Option @strong{-dummy} prevents this kind of real action and rather shows the

The outmost complicity to potentially unwise actions is offered by

|
option @strong{-dummy_force}. If given together with a single device name or

with option -plug_test it will act like -dummy -DO_WRITE with this device,

|
@strong{look_for_iso++}
|
|
@*
|
|
Option -look_for_iso is given and an ISO 9660 filesystem is detected.
|
|
This reason overrides any "has_XYZ-" reason.
|
|
@*
|
|
@strong{looks_like_cd_drive-}
|
|
@*
|
|
A given device name looks like the name of an optical drive: sr[0-9]*.
|
|
Use program @strong{xorrecord} for this kind of devices.
|
|
@*
|
|
@strong{looks_like_disk_partition-}
|
|
@*
|
|
A given device name looks like the name of a partition. Expected are names
|
|
of base devices, like "sde", not of their partitions, like "sde1".
|
|
@*
|
|
@strong{looks_like_floppy-}
|
|
@*
|
|
A given device name looks like the name of a floppy disk drive: fd[0-9]*.
|
|
@*
|
|
@strong{looks_like_loopdev-}
|
|
@*
|
|
A given device name looks like the name of a loop device: loop[0-9]*.
|
|
@*
|
|
@strong{looks_like_ramdev-}
|
|
@*
|
|
A given device name looks like the name of a RAM block device: zram[0-9]*.
|
|
@*
|
|
@strong{lsblk_no_size-}
|
|
@*
|
|
A size test is given by -max_size, -min_size, or -image_file but the size of
|
|
the device cannot be inquired by lsblk. This is supposed to happen only with
|
|
given inappropriate device names.
|
|
@*
|
|
@strong{mmcblk+}
|
|
@*
|
|
The device name looks like a directly connected memory card.
|
|
@*
|
|
@strong{name_with_slash-}
|
|
@*
|
|
A given device name contains '/' characters.
|
|
@*
|
|
@strong{no_bus_info-}
|
|
@*
|
|
The device is not a memory card and lsblk reports nothing about the way how
|
|
it is connected to the computer.
|
|
@*
|
|
@strong{no_fs_while_not_su-}
|
|
@*
|
|
No filesystem is reported by lsblk and the program does not believe to have
|
|
run it with superuser powers. There is the risk that lsblk silently failed
|
|
to detect existing filesystems.
|
|
@*
|
|
@strong{no_iso9660-}
|
|
@*
|
|
Option -look_for_iso is given but no ISO 9660 filesystem is detected.
|
|
@*
|
|
@strong{not_usb-}
|
|
@*
|
|
The device is not a memory card and lsblk reports that it is connected by
|
|
something other than USB.
|
|
@*
|
|
@strong{size_too_large-}
|
|
@*
|
|
Option -max_size is given with a size smaller than the size of the device.
|
|
@*
|
|
@strong{size_too_small-}
|
|
@*
|
|
Option -min_size or -image_file is given with size or file size larger than
|
|
the size of the device.
|
|
@*
|
|
@strong{usb+}
|
|
@*
|
|
The device is reported by lsblk to be connected via USB.

@kindex -plug_test detect target device plugging
|
|
@cindex Target device, detect by plugging, @minus{}plug_test
|
|
Find the target device by asking the user to press the Enter key when the
|
|
desired target is _not_ plugged in, to then plug it in, and to press Enter
|
|
again.
|
|
@*
|

This overrides device names and option -list_all.
|
|
The found device is then shown with advice, vendor, and model.
|

Option -DO_WRITE is obeyed if given.
|

@item -max_size n[M|G|T]
|
|
@kindex -max_size set size limit for device
|
|
@cindex Device size, set limit, -max_size
|
|
Set the upper byte size limit for advisable devices. Plain numbers get rounded
|
|
down to full millions. As suffix are recognized: M = million, G = billion,
|
|
T = trillion.
|
|
@*
|
|
Be generous to avoid problems with GB < GiB.
|
|
@c man .TP
|
|
@item -min_size n[M|G|T]
|
|
@kindex -min_size set size limit for device
|
|
@cindex Device size, set limit, -min_size
|
|
Set the lower byte size limit for advisable devices. After processing like
|
|
with -max_size, one million gets added to the size limit.
|
|
@c man .TP
|
|
@item -look_for_iso
|
|
@kindex -look_for_iso demand presence of ISO 9660
|
|
@cindex ISO 9660, demand presence on target, @minus{}look_for_iso
|
|
Demand presence of an ISO 9660 filesystem. If so, then any further filesystem
|
|
type is acceptable on that device.
|
|
@*
|
|
If this option is missing, only ISO 9660 and VFAT filesystems are accepted.
|
|
@c man .TP
|
|
@item -with_sudo
|
|
@kindex -with_sudo run lsblk, umount, dd by sudo
|
|
@cindex lsblk, umount, dd, run by sudo, -with_sudo
|
|
Run 'lsblk -o FSTYPE' by sudo. If no filesystems are detected on a device while
|
|
the program has no superuser power, then the device is not advised. Option
|
|
-with_sudo avoids this refusal without the need to run the whole
|
|
program as superuser.
|
|
@*
|
|
If -DO_WRITE -with_sudo is given, then the programs umount and dd will be run
|
|
by sudo, too.
|
|
@c man .TP
|
|
@item -trust_lsblk_udev
|
|
@kindex -trust_lsblk_udev suppress no_fs_while_not_su-
|
|
@cindex suppress no_fs_while_not_su-, -trust_lsblk_udev
|
|
Suppress the reason no_fs_while_not_su- if lsblk is linked with libudev.so.
|
|
In this case it is likely that lsblk can retrieve FSTYPE even if run
|
|
by a non-priviledged user.
|
|
@*
|
|
This option is intended for use by frontend programs which are certain
|
|
that they do not encounter a udev-using version of lsblk which nevertheless
|
|
fails to detect existing filesystems. Human users should better acquire
|
|
superuser powers if reason no_fs_while_not_su- is reported.
|
|
@c man .TP
|
|
@item -image_file PATH
|
|
@kindex -image_file set path of disk image file
|
|
@cindex disk image file, set path, -image_file
|
|
Set the path of the image file which shall be written to a device. Its size
|
|
will be set as -min_size.
|
|
@c man .TP
|
|
@item -DO_WRITE
|
|
@kindex -DO_WRITE write image file to device
|
|
@cindex disk image file, write to device, -DO_WRITE
|
|
Write the given -image_file to the one advisable device that is found. If more
|
|
than one such device is found, then they get listed but no writing happens.
|
|
@*
|
|
In this case, to get a real write run, consider unplugging unneeded devices,
|
|
or using option -plug_test, or a re-run with one of the advised device names
|
|
as additional argument.
|
|
@c man .TP
|
|
@item -no_pacifier
|
|
@kindex -no_pacifier do not show dd progress
|
|
@cindex dd progress, do not show, -no_pacifier
|
|
Do not use dd options to print progress messages and to perform synchronized
|
|
output. These options are used by default if program dd offers progress
|
|
messages.
|
|
@c man .TP
|
|
@item -dummy
|
|
@kindex -dummy report but do not perform
|
|
@cindex only report, do not perform, -dummy
|
|
Report the -DO_WRITE actions but do not perform them.
|
|
@c man .TP
|
|
@item -dummy_force
|
|
@kindex -dummy_force show raw copy commands
|
|
@cindex raw copy commands, show, -dummy_force
|
|
If a single device name is given, do a run of -dummy -DO_WRITE even against
|
|
the advice of this program. This probably shows you ways to shoot your own
|
|
foot.
|
|
@c man .TP
|
|
@item -version
|
|
@kindex -version print version text to stdout
|
|
@cindex version text, print to stdout, -version
|
|
Print the program name, version text, and timestamp to stdout and then end
|
|
the program.
|
|
@c man .TP
|
|
@item -help
|
|
@kindex -help print help text to stdout
|
