Where an option takes a RANGE of files, thumbnails, or other data, they are numbered beginning at 1. A range is a 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.

--debug-loglevel LEVEL (since 2.5.5)

The verbosity of debug logging. Possible values with incrementing verbosity are: error, debug, data, all. Default is all.

--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).

-v, --version

Display version and exit.

-h, --help

Display options and short description.

--usage

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 SPEED

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, in addition, %n for the number, %C for the filename suffix, %f for the filename without suffix, %F for the foldername, %: 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. USBIDS must 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 the camera and driver abilities specified in the libgphoto2 driver. This all does not query the camera, it uses data provided by the library. Use --summary to query an overview of the camera.

-f, --folder FOLDER

Specify camera folder (default="/").

-R, --recurse

Recursion (default for download).

--no-recurse

No recursion (default for deletion).

-l, --list-folders

--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.

--upload-meta-data FILENAME

Upload meta data for the specific file, taken from a file prefix with meta_ .

--get-meta-data RANGE

Get meta data given in range.

--get-all-meta-data

Get all meta data from folder.

--force-overwrite

Overwrite files without asking.

--skip-existing

Skip files if they exist already on the local directory.

--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 (defaults to --no-recurse).

-u, --upload-file FILENAME

Upload a file to camera.

--capture-preview

Capture a quick preview.

--show-preview

Capture a quick preview and displays it in the terminal using Ascii Art (if aalib was used during build).

-F COUNT, --frames COUNT

Number of frames to capture in one run. Default is 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.

--reset-interval

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 and keep it on the camera.

--capture-image-and-download

Capture an image and download it immediately to the computer.

--trigger-capture

Triggers the capture an image and return. If you want to get the image downloaded, see --wait-event-and-download.

This feature is only available for some camera brands and drivers.

--keep

When doing --capture-image-and-download or interval capture, this option will keep the images on the memory card of the camera.

--no-keep

When doing --capture-image-and-download or interval capture, this option will not keep the images on the memory card of the camera after downloading them during capture. (default)

--keep-raw

When doing --capture-image-and-download or interval capture, this option will keep the RAW images on the memory card of the camera, but still download the JPEG images. This is useful when doing dual mode capture and you want to review the JPEGs already during capture.

--capture-movie SECONDS

Capture a movie. If the camera supports previews, this will capture a stream of previews (motion-jpeg) as fast as the camera can.

If not argument is specified, it will capture preview frames until you press Ctrl-C. Arguments that can be specified are either seconds of capture or number of preview frames.

--capture-sound

Capture an audio clip. No driver supports this at this time.

--capture-tethered SECONDS, MILLISECONDS, COUNT or MATCHSTRING

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 newer Canon EOS and Nikon DLSR work.

--wait-event SECONDS, MILLISECONDS, COUNT or MATCHSTRING, --wait-event-and-download SECONDS, MILLISECONDS, COUNT or MATCHSTRING

Lets gphoto2 wait for notifications from the camera for various events. This is useful for seeing what the camera does and waiting for objects to be added. The objects are kept on camera in the "--wait-event" version, with "--wait-event-and-download" they are downloaded.

--wait-event-and-download is equivalent to --capture-tethered.

The time to wait can be either specified as full seconds with a "s" suffix, a number of milliseconds with a "ms" suffix, as a number of events (just a number), or a sub-string to match. If nothing happens, a timeout is generated after 1 second, so a "wait-event=5" will take at most 5 seconds. A "--wait-event=5s" will take exactly 5 second.

If no argument is given, the wait time is 1 million events (basically forever).

In the download variant this can be used 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 newer Canon EOS and Nikon DSC are known to work.

--show-info RANGE

Show information for a single or multiple images, like width, height, size and/or the capture time

--config

Starts a ncurses based text configuration menu. gphoto2 needs to built against CDK for this feature.

--list-config

List all configuration entries.

--list-all-config

List all configuration entries and their values and choices.

This command is a combination of --list-config and calling --get-config on all the 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.

--set-config CONFIGENTRY=CONFIGVALUE

Set the specified configuration entry. For lists of choices of values this setting first looks up CONFIGVALUE as value and then as index into the choice list. Since this is not fully clear, you can use --set-config-index or --set-config-value to be more clear what is searched for.

Look at the output of --get-config to see what values are possible to set here.

--set-config-index CONFIGENTRY=CONFIGINDEX

Set the specified configuration entry by specifying the index into the list of choices for the configuration value. This of course only works for configuration settings that offer list of choices.

Look at the output of --get-config to see what indices are possible to set here.

--set-config-value CONFIGENTRY=CONFIGVALUE

Set the specified configuration entry by specifying its new value. For lists of choices the value is looked up and set.

Look at the output of --get-config to see what values are possible to set here.

--reset

Resets the specified (or autodetected) USB port.

This command resets the USB port of either the first auto-detected camera, or the port specified with --port usb:XXX,YYY. This option is useful if somehow the protocol talking to the camera locked up and simulates plugging out and in the camera.

--storage-info

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 SHELL MODEfor a detailed description.
