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 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.

--parsable
    Outputs the filelist in a line based format that could be passed into a shellscript or other filter.

--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.

--filenumber FILENUMBER
    If you specify the filename using the --filename option and use the %n pattern, this pattern usually starts at 1. For incremental usage, you can use --filenumber to have it start at another number FILENUMBER.

--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 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
    List folders in folder.

-L, --list-files
    List files in folder.

-m, --mkdir NAME
    Create a directory.

-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.

--get-exif RANGE
    Get Exif given in range.

--get-all-exif
    Get all Exif from folder.

--upload-metadata FILENAME
    Upload meta data for the specific file, taken from a file prefix with meta_ .

--get-metadata RANGE
    Get meta data given in range.

--get-all-metadata
    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.

-B--bulb SECONDS
    Do a bulb capture for the specified amount of seconds.

--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.

--reverse
    When doing file operations like --get-all-files, -P or -T it reverts the order of files to download.

--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.

    It is also possible to wait for MATCHSTRING, for things like CAPTURECOMPLETE, FILEADDED, TIMEOUT or other events printed out.

    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.

    If gphoto2 receives a SIGUSR1 during the wait, it will immediately take a picture (similar to “--capture-image”), and depending on mode either leave it on camera or download it. (Since 2.5.28)

    If gphoto2 receives a SIGUSR2 during the wait, it will safely end the tethering. (Since 2.5.25)

--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.

capture-preview
    Captures a preview image and downloads it from the camera.

list-config
    Lists all configuration values.

get-config NAME
    Gets the configuration specified by “NAME”.

set-config NAME=VALUE
    Sets the configuration specified by “NAME” to “VALUE”.

set-config-value NAME=VALUE
    Sets the configuration specified by “NAME” to “VALUE”.

set-config-index NAME=VALUE
    Sets the configuration specified by “NAME” to the “INDEX” into the list of choices. Works only for Menu or Radio button entries.

wait-event COUNT or SECONDS
    Waits for events from the camera for the specified time in SECONDS (if suffixed with s) or the COUNT of events from the camera, where every seconds a timeout event happens. Newly added images are kept on the camera.

    Default is 1 event.

wait-event-and-download COUNT or SECONDS, capture-tethered COUNT or SECONDS
    Waits for events from the camera for the specified time in SECONDS (if suffixed with s) or the COUNT of events from the camera, where every seconds a timeout event happens. Newly added images are downloaded from the camera.

    Default is 1 event.

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 with non-standard installations.

IOLIBS
    If set, defines the directory where the libgphoto2_port library looks for its I/O drivers (iolibs). You only need to set this with non-standard installations.

LD_DEBUG
    Set this to all to receive lots of debug information regarding library loading on ld based systems.

USB_DEBUG
    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 and in tethering or wait-event 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.

SIGUSR2 (since 2.5.26)
    In tethering or wait-event mode, receiving a SIGUSR2 signal ends the tethering or wait-event mode. This is useful if you do not know the end before hand, but still want to safely exit the waiting.
