DESCRIPTION
libgphoto2(3) is a cross-platform digital camera library,
and gphoto2(1) is a command-line client for it.
Where an option takes a RANGE of files, thumbnails, or other
data, they are numbered beginning at 1. A range is a
SunOS Las0t change: 2006-12-21August 2006 1
The gPhoto2 Reference (the man GPHOTO2(1)
comma-separated list of numbers or spans (first-last).
Ranges are XOR (exclusive or), so that 1-5,3,7 is equivalent
to 1,2,4,5,7.
--debug
Turn on debugging output. Debugging output is written to
stderr by default, or to the filename given to the
--debug-logfile option.
--debug-logfile FILENAME (since 2.3.0)
The logfile to write the debugging info to, if --debug
is given.
--hook-script FILENAME (new after 2.3.0)
Execute the hook script FILENAME every time a certain
event happens within gphoto2. The hook script reads the
environment variable ACTION. It must ignore ACTION
values unknown to it.
ACTION=init
gphoto2 has just been initialized. If the hook
script returns with a non-zero exit code now,
gphoto2 will abort.
ACTION=start
gphoto2 has just finished parsing the command
line and is about to start executing the
commands given on the command line.
ACTION=download
gphoto2 has just downloaded a file to the
computer, storing it in the file indicated by
the environment variable ARGUMENT.
ACTION=stop
gphoto2 is about to finish. Do your final
cleanups here.
All other environment variables are passed to the
hook script unchanged. You can make use of that to
pass data to the hook script.
Hook script may be specified in the
~/.gphoto/settings file as
gphoto2=hook-script=filename.
-q, --quiet
Quiet output (default=verbose).
SunOS Las0t change: 2006-12-21August 2006 2
The gPhoto2 Reference (the man GPHOTO2(1)
-v, --version
Display version and exit.
-h, --help
Display a short usage message.
--list-cameras
List supported camera models.
--list-ports
List supported port devices.
--stdout
Send file to stdout.
--stdout-size
Print filesize before data.
--auto-detect
List auto-detected cameras and the ports to which they
are connected.
--port PATH
Specify port device. The --list-ports prints a list of
valid, usable ports. In case of multiple USB cameras,
the --auto-detect shows you the specific port each
camera is connected to.
--speed SPED
Specify serial transfer speed.
--camera MODEL
Specify camera model. The --list-cameras option prints a
list of all explicitly supported cameras.
Most model names contain spaces: remember to enclose the
name in quotes so that the shell knows it is one
parameter. For example: --camera "Kodak DC240".
Note that if you specify --camera, you must also specify
--port. Otherwise the --camera option will be silently
ignored.
--filename FILENAME
When downloading files from the camera, specify the file
name or file name pattern to use when storing the
downloaded file on the local disk. When uploading a file
to the camera, specify the filename to store the
uploaded file as on the camera.
The --filename option accepts %a, %A, %b, %B, %d, %H,
%k, %I, %l, %j, %m, %M, %S, %y, %%, (see date(1)) and,
SunOS Las0t change: 2006-12-21August 2006 3
The gPhoto2 Reference (the man GPHOTO2(1)
in addition, %n for the number, %C for the filename
suffix, %f for the filename without suffix, %: for the
complete filename in lowercase.
Note that %: is still in alpha stage, and the actual
character or syntax may still be changed. E.g. it might
be possible to use %#f and %#C for lower case versions,
and %^f and %^C for upper case versions.
%n is the only conversion specifier to accept a padding
character and width: %03n will pad with zeros to width 3
(e.g. print the number 7 as 007). Leaving out the
padding character (e.g. %3n) will use an implementation
specific default padding character which may or may not
be suitable for use in file names.
Default value for this option can be specified in the
~/.gphoto/settings file as gphoto2=filename=value.
--usbid USBIDS
(Expert only) Override USB IDs.
USBIDSmust be of the form
DetectedVendorID:DetectedProductID=TreatAsVendorID:TreatAsProductID
to treat any USB device detected as
DetectedVendorID:DetectedProductID as
TreatAsVendorID:TreatAsProductID instead. All the
VendorIDs and ProductIDs should be hexadecimal numbers
beginning in C notation, i.e. beginning with '0x'.
Example: --usbid 0x4a9:0x306b=0x4a9:0x306c
-a, --abilities
Display camera abilities.
-f, --folder FOLDER
Specify camera folder (default="/").
-R, --recurse
Recursion (default for download).
--no-recurse
No recursion (default for deletion).
-l, --list-folders
List folders in folder.
-L, --list-files
List files in folder.
-m, --mkdir NAME
Create a directory.
SunOS Las0t change: 2006-12-21August 2006 4
The gPhoto2 Reference (the man GPHOTO2(1)
-r, --rmdir NAME
Remove a directory.
-n, --num-files
Display number of files.
-p, --get-file RANGE
Get files given in range.
-P, --get-all-files
Get all files from folder.
-t, --get-thumbnail RANGE
Get thumbnails given in range.
-T, --get-all-thumbnails
Get all thumbnails from folder.
--get-raw-data RANGE
Get raw data given in range.
--get-all-raw-data
Get all raw data from folder.
--get-audio-data RANGE
Get audio data given in range.
--get-all-audio-data
Get all audio data from folder.
--force-overwrite
Overwrite files without asking.
--new
Only get not already downloaded files. This option
depends on camera support of flagging already downloaded
images and is not available for all drivers.
-d, --delete-file RANGE
Delete files given in range.
-D, --delete-all-files
Delete all files in folder.
-u, --upload-file FILENAME
Upload a file to camera.
--capture-preview
Capture a quick preview.
-F COUNT, --frames COUNT
Number of frames to capture in one run. Default is
SunOS Las0t change: 2006-12-21August 2006 5
The gPhoto2 Reference (the man GPHOTO2(1)
infinite number of frames.
-I SECONDS, --interval SECONDS
Time between capture of multiple frames.
(Since 2.4) If SIGUSR1 signal is received, a picture is
taken immediately without waiting for the end of the
current interval period (see the section called
SIGNALS). A value of -1 will let gphoto2 wait forever,
i.e. until a signal arrives. See also --reset-interval
(since 2.4).
--reset-interval (since 2.4)
Setting this option will reset the time interval to the
value given by the -I--interval option when a SIGUSR1
signal is received in time-lapse mode.
--capture-image
Capture an image.
--capture-movie
Capture a movie.
--capture-sound
Capture an audio clip.
--capture-tethered
Lets gphoto2 wait for notifications from the camera that
an object was added. This is useful for tethered
capture, where pressing the shutter on the camera
immediately transfer the image to the machine for
processing.
Together with the --hook-script to immediately
postprocess or display the images this can help a studio
workflow.
This option requires support in the driver and by the
camera, currently only Nikon DSC are known to work.
--show-info RANGE
Show info.
--list-config
List all configuration entries.
--get-config CONFIGENTRY
Get the specified configuration entry.
This command will list the type, the current value and
also the available options of this configuration value.
SunOS Las0t change: 2006-12-21August 2006 6
The gPhoto2 Reference (the man GPHOTO2(1)
--set-config CONFIGENTRY=CONFIGVALUE
Set the specified configuration entry.
Look at the output of --get-config to see what values
are possible to set here.

Display information about the camera's storage media.
--summary
Summary of camera status.
--manual
Camera driver manual.
--about
About the camera driver.
--shell
Start the gphoto2 shell, an interactive environment. See
SHEL MODEfor a detailed description.

support).
help, ?
Displays command usage.
exit, quit, q
Exit the gphoto2 shell.
ENVIRONMENT VARIABLES
CAMLIBS
If set, defines the directory where the libgphoto2
library looks for its camera drivers (camlibs). You only
need to set this on OS/2 systems and broken/test
installations.
IOLIBS
If set, defines the directory where the libgphoto2port
library looks for its I/O drivers (iolibs). You only
need to set this on OS/2 systems and broken/test
installations.
LDEBUG
Set this to all to receive lots of debug information
regarding library loading on ld based systems.
USBDEBUG
If set, defines the numeric debug level with which the
libusb library will print messages. In order to get some
debug output, set it to 1.
SIGNALS
SIGUSR1 (since 2.4)
In time-lapse capture mode, receiving a SIGUSR1 signal
makes gphoto2 take a picture immediately.
If the --reset-interval option is given, the time
counter is reset to the value given by the -I--interval
option. Note that the camera will need some time (from
50ms to a few seconds) to actually capture the image.
