.SH "DESCRIPTION"
.PP
libgphoto2(3)
is a cross\-platform digital camera library, and
gphoto2(1)
is a command\-line client for it\&.
.PP
Where an option takes a
\fIRANGE\fR
of files, thumbnails, or other data, they are numbered beginning at 1\&. A range is a comma\-separated list of numbers or spans (\(lq\fIfirst\fR\-\fIlast\fR\(rq)\&. Ranges are XOR (exclusive or), so that
\(lq1\-5,3,7\(rq
is equivalent to
\(lq1,2,4,5,7\(rq\&.
.PP
\fB\-\-debug\fR
.RS 4
Turn on debugging output\&. Debugging output is written to stderr by default, or to the filename given to the
\fB\-\-debug\-logfile\fR
option\&.
.RE
.PP
\fB\-\-debug\-logfile\fR \fIFILENAME\fR (since 2\&.3\&.0)
.RS 4
The logfile to write the debugging info to, if
\fB\-\-debug\fR
is given\&.
.RE
.PP
\fB\-\-debug\-loglevel\fR \fILEVEL\fR (since 2\&.5\&.5)
.RS 4
The verbosity of debug logging\&. Possible values with incrementing verbosity are:
\fBerror\fR,
\fBdebug\fR,
\fBdata\fR,
\fBall\fR\&. Default is
\fBall\fR\&.
.RE
.PP
\fB\-\-hook\-script\fR \fIFILENAME\fR (new after 2\&.3\&.0)
.RS 4
Execute the hook script
\fIFILENAME\fR
every time a certain event happens within
\fBgphoto2\fR\&. The hook script reads the environment variable
\fBACTION\fR\&. It must ignore
\fBACTION\fR
values unknown to it\&.
.PP
\fBACTION\fR=init
.RS 4
\fBgphoto2\fR
has just been initialized\&. If the hook script returns with a non\-zero exit code now,
\fBgphoto2\fR
will abort\&.
.RE
.PP
\fBACTION\fR=start
.RS 4
\fBgphoto2\fR
has just finished parsing the command line and is about to start executing the commands given on the command line\&.
.RE
.PP
\fBACTION\fR=download
.RS 4
\fBgphoto2\fR
has just downloaded a file to the computer, storing it in the file indicated by the environment variable
\fBARGUMENT\fR\&.
.RE
.PP
\fBACTION\fR=stop
.RS 4
\fBgphoto2\fR
is about to finish\&. Do your final cleanups here\&.
.RE
.sp
All other environment variables are passed to the hook script unchanged\&. You can make use of that to pass data to the hook script\&.
.sp
Hook script may be specified in the
~/\&.gphoto/settings
file as
\fBgphoto2=hook\-script=\fR\fIfilename\fR\&.
.RE
.PP
\fB\-q\fR, \fB\-\-quiet\fR
.RS 4
Quiet output (default=verbose)\&.
.RE
.PP
\fB\-v\fR, \fB\-\-version\fR
.RS 4
Display version and exit\&.
.RE
.PP
\fB\-h\fR, \fB\-\-help\fR
.RS 4
Display options and short description\&.
.RE
.PP
\fB\-\-usage\fR
.RS 4
Display a short usage message\&.
.RE
.PP
\fB\-\-list\-cameras\fR
.RS 4
List supported camera models\&.
.RE
.PP
\fB\-\-list\-ports\fR
.RS 4
List supported port devices\&.
.RE
.PP
\fB\-\-stdout\fR
.RS 4
Send file to stdout\&.
.RE
.PP
\fB\-\-stdout\-size\fR
.RS 4
Print filesize before data\&.
.RE
.PP
\fB\-\-parsable\fR
.RS 4
Outputs the filelist in a line based format that could be passed into a shellscript or other filter\&.
.RE
.PP
\fB\-\-auto\-detect\fR
.RS 4
List auto\-detected cameras and the ports to which they are connected\&.
.RE
.PP
\fB\-\-port\fR \fIPATH\fR
.RS 4
Specify port device\&. The
\fB\-\-list\-ports\fR
prints a list of valid, usable ports\&. In case of multiple USB cameras, the
\fB\-\-auto\-detect\fR
shows you the specific port each camera is connected to\&.
.RE
.PP
\fB\-\-speed\fR \fISPEED\fR
.RS 4
Specify serial transfer speed\&.
.RE
.PP
\fB\-\-camera\fR \fIMODEL\fR
.RS 4
Specify camera model\&. The
\fB\-\-list\-cameras\fR
option prints a list of all explicitly supported cameras\&.
.sp
Most model names contain spaces: remember to enclose the name in quotes so that the shell knows it is one parameter\&. For example:
\fB\fB\-\-camera\fR\fR\fB "Kodak DC240"\fR\&.
.sp
Note that if you specify
\fB\fB\-\-camera\fR\fR, you must also specify
\fB\fB\-\-port\fR\fR\&. Otherwise the
\fB\fB\-\-camera\fR\fR
option will be silently ignored\&.
.RE
.PP
\fB\-\-filename\fR \fIFILENAME\fR
.RS 4
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\&.
.sp
The
\fB\-\-filename\fR
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\&.
.sp
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\&.
.sp
%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
\(lq007\(rq)\&. 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\&.
.sp
Default value for this option can be specified in the
~/\&.gphoto/settings
file as
\fBgphoto2=filename=value\fR\&.
.RE
.PP
\fB\-\-filenumber\fR \fIFILENUMBER\fR
.RS 4
If you specify the filename using the
\fB\-\-filename\fR
option and use the %n pattern, this pattern usually starts at 1\&. For incremental usage, you can use
\fB\-\-filenumber\fR
to have it start at another number FILENUMBER\&.
.RE
.PP
\fB\-\-usbid\fR \fI\fIUSBIDS\fR\fR
.RS 4
(Expert only) Override
USB
IDs\&.
\fI \fR\fI\fIUSBIDS\fR\fRmust be of the form
\fI \fR\fI\fIDetectedVendorID\fR\fR\fI:\fR\fI\fIDetectedProductID\fR\fR\fI=\fR\fI\fITreatAsVendorID\fR\fR\fI:\fR\fI\fITreatAsProductID\fR\fR
to treat any USB device detected as
\fI\fIDetectedVendorID\fR\fR\fI:\fR\fI\fIDetectedProductID\fR\fR
as
\fI\fITreatAsVendorID\fR\fR\fI:\fR\fI\fITreatAsProductID\fR\fR
instead\&. All the VendorIDs and ProductIDs should be hexadecimal numbers beginning in C notation, i\&.e\&. beginning with \*(Aq0x\*(Aq\&.
.sp
Example:
\fB\-\-usbid \fR\fB\fI0x4a9:0x306b=0x4a9:0x306c\fR\fR
.RE

.sp
Together with the

\fB\-\-wait\-event \fR\fB\fISECONDS, MILLISECONDS, COUNT or MATCHSTRING\fR\fR, \fB\-\-wait\-event\-and\-download \fR\fB\fISECONDS, MILLISECONDS, COUNT or MATCHSTRING\fR\fR
.RS 4
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
\(lq\-\-wait\-event\(rq
version, with
\(lq\-\-wait\-event\-and\-download\(rq
they are downloaded\&.
.sp
\-\-wait\-event\-and\-download is equivalent to \-\-capture\-tethered\&.
.sp
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
\(lqwait\-event=5\(rq
will take at most 5 seconds\&. A
\(lq\-\-wait\-event=5s\(rq
will take exactly 5 second\&.
.sp
It is also possible to wait for MATCHSTRING, for things like CAPTURECOMPLETE, FILEADDED, TIMEOUT or other events printed out\&.
.sp
If no argument is given, the wait time is 1 million events (basically forever)\&.
.sp
In the download variant this can be used together with the
\fB\-\-hook\-script\fR
to immediately postprocess or display the images this can help a studio workflow\&.
.sp
This option requires support in the driver and by the camera\&.
.sp
If gphoto2 receives a SIGUSR1 during the wait, it will immediately take a picture (similar to
\(lq\-\-capture\-image\(rq), and depending on mode either leave it on camera or download it\&. (Since 2\&.5\&.28)
.sp
If gphoto2 receives a SIGUSR2 during the wait, it will safely end the tethering\&. (Since 2\&.5\&.25)
