This is the default action, i.e., the command \fIexiv2 image.jpg\fP will print a summary of the image Exif metadata. .TP .B ex | extract Extract metadata to *.exv, XMP sidecar (*.xmp) and thumbnail image files. Modification commands can be applied on-the-fly. .TP .B in | insert Insert metadata from corresponding *.exv, XMP sidecar (*.xmp) and thumbnail files. Use option \fB\-S\fP \fI.suf\fP to change the suffix of the input files. Since files of any supported format can be used as input files, this command can be used to copy the metadata between files of different formats. Modification commands can be applied on-the-fly. .TP .B rm | delete Delete image metadata from the files. .TP .B ad | adjust Adjust Exif timestamps by the given time. Requires at least one of the options \fB\-a\fP \fItime\fP, \fB\-Y\fP \fIyrs\fP, \fB\-O\fP \fImon\fP or \fB\-D\fP \fIday\fP. .TP .B mo | modify Apply commands to modify (add, set, delete) the Exif, IPTC and XMP metadata of image files. Requires option \fB\-c\fP, \fB\-m\fP or \fB\-M\fP. .TP .B mv | rename Rename files and/or set file timestamps according to the Exif create timestamp. Uses the value of tag Exif.Photo.DateTimeOriginal or, if not present, Exif.Image.DateTime to determine the timestamp. The filename format can be set with \fB\-r\fP \fIfmt\fP, timestamp options are \fB\-t\fP and \fB\-T\fP. .TP .B fi | fixiso Copy the ISO setting from one of the proprietary Nikon or Canon makernote ISO tags to the regular Exif ISO tag, Exif.Photo.ISOSpeedRatings. Does not overwrite an existing standard Exif ISO tag. .TP .B fc | fixcom Fix the character encoding of Exif Unicode user comments. Decodes the comment using the auto-detected or specified character encoding and writes it back in UCS-2. Use option \fB\-n\fP to specify the current encoding of the comment if necessary. .br .ne 40 .SH COMMAND SUMMARY .sp 1 .nf exiv2 [ opt [arg] ]+ [ act ] file ... .sp 1 option [arg] long option description -a tim --adjust Modify time stamps.

Verbose version is supported on Windows (MSVC, Cygwin and MinGW builds), MacOSX and Linux and is provided for test and debugging. .TP .B \-v Be verbose during the program run. .TP .B \-q Silence warnings and error messages from the Exiv2 library during the program run (quiet). Note that options \fB\-v\fP and \fB\-q\fP can be used at the same time. .TP .B \-Q \fIlvl\fP Set the log-level to 'd'(ebug), 'i'(nfo), 'w'(arning), 'e'(rror) or 'm'(ute). The default log-level is 'w'. \fB\-Qm\fP is equivalent to \fB\-q\fP. All log messages are written to standard error. .TP .B \-b Show large binary values (default is to suppress them). .TP .B \-u Show unknown tags (default is to suppress tags which don't have a name). .TP .B \-g \fIkey\fP Only keys which match the given key (grep). .br Multiple \fB\-g\fP options can be used to grep info for several keys. This option uses the system regular expression engine: see man 3 regex. Platforms which do not support regex use key for a substring match. You can determine the availability of regex using the command: exiv2 -v -V -g have_regex .nf exiv2 \-g Date \-pt R.jpg Exif.Image.DateTime Ascii 20 2012:08:07 16:01:05 Exif.Photo.DateTimeOriginal Ascii 20 2011:09:18 16:25:48 Exif.Photo.DateTimeDigitized Ascii 20 2011:09:18 16:25:48 .fi .TP .B \-K \fIkey\fP Only report data for given key. .br Multiple \fB\-K\fP options can be used to report more than a single key. .nf exiv2 \-K Exif.Photo.DateTimeDigitized -K Exif.Photo.DateTimeOriginal \-pt R.jpg Exif.Photo.DateTimeOriginal Ascii 20 2011:09:18 16:25:48 Exif.Photo.DateTimeDigitized Ascii 20 2011:09:18 16:25:48 .fi .TP .B \-n \fIenc\fP Charset to use to decode Exif Unicode user comments. \fIenc\fP is a name understood by \fBiconv_open\fP(3), e.g., 'UTF-8'. .TP .B \-k Preserve file timestamps when updating files (keep). Can be used with all options which update files. The flag is ignored by read-only options. .TP .B \-t Set the file timestamp according to the Exif create timestamp in addition to renaming the file (overrides \fB\-k\fP). This option is only used with the 'rename' action. .TP .B \-T Only set the file timestamp according to the Exif create timestamp, do not rename the file (overrides \fB\-k\fP). This option is only used with the 'rename' action. Note: On Windows you may have to set the TZ environment variable for this option to work correctly. .TP .B \-f Do not prompt before overwriting existing files (force overwrite). .TP .B \-F Do not prompt before renaming files (Force rename). Appends '_1' ('_2', ...) to the name of the new file. .TP .B \-a \fItime\fP Time adjustment in the format [\-]HH[:MM[:SS]]. This option is only used with the 'adjust' action. Examples: 1 adds one hour, 1:01 adds one hour and one minute, \-0:00:30 subtracts 30 seconds. .TP .B \-Y \fIyrs\fP Time adjustment by a positive or negative number of years, for the 'adjust' action. .TP .B \-O \fImon\fP Time adjustment by a positive or negative number of months, for the 'adjust' action. .TP .B \-D \fIday\fP Time adjustment by a positive or negative number of days, for the 'adjust' action. .TP .B \-p \fImode\fP Print mode for the 'print' action. Possible modes are: .br s : print a summary of the Exif metadata (the default) .br a : print Exif, IPTC and XMP metadata (shortcut for \-Pkyct) .br t : interpreted (translated) Exif tags (\-PEkyct) .br v : plain Exif tag values (\-PExgnycv) .br h : hexdump of the Exif data (\-PExgnycsh) .br i : IPTC datasets (\-PIkyct) .br x : XMP properties (\-PXkyct) .br c : JPEG comment .br p : list available image previews, sorted by preview image size in pixels .br S : print image structure information (jpg, png and tiff only) .br X : print "raw" XMP (jpg, png and tiff only) .TP .B \-P \fIflgs\fP Print flags for fine control of the tag list ('print' action). Allows control of the type of metadata as well as data columns included in the print output. Valid flags are: .br E : include Exif tags in the list .br I : IPTC datasets .br X : XMP properties .br x : print a column with the tag number .br g : group name .br k : key .br l : tag label .br n : tag name .br y : type .br c : number of components (count) .br s : size in bytes .br v : plain data value .br t : interpreted (translated) data .br h : hexdump of the data .TP .B \-d \fItgt\fP Delete target(s) for the 'delete' action. Possible targets are: .br a : all supported metadata (the default) .br e : Exif section .br t : Exif thumbnail only .br i : IPTC data .br x : XMP packet .br c : JPEG comment .TP .B \-i \fItgt\fP Insert target(s) for the 'insert' action. Possible targets are the same as those for the \fB\-d\fP option, plus an optional modifier: .sp 1 X : Insert metadata from an XMP sidecar file .xmp. The remaining insert targets determine what metadata to insert from the sidecar file. Possible are Exif, IPTC and XMP and the default is all of these. Note that the inserted XMP properties include those converted to Exif and IPTC. .br This is option is intended for "filter" operations on the XMP such as: .br $ exiv2 -e{tgt}- \fIfilename\fP | xmllint .... | exiv2 -i{tgt}- \fIfilename\fP .sp 1 Only JPEG thumbnails can be inserted (not TIFF thumbnails), they need to be named \fIfile\fP\-thumb.jpg. .TP .B \-e \fItgt\fP Extract target(s) for the 'extract' action. Possible targets are the same as those for the \fB\-d\fP option, plus a target to extract preview images and a modifier to generate an XMP sidecar file: .br p[[, ...]] : Extract preview images. The optional comma separated list of preview image numbers is used to determine which preview images to extract. The available preview images and their numbers are displayed with the 'print' option \fB\-pp\fP. .sp 1 X : Extract metadata to an XMP sidecar file .xmp. The remaining extract targets determine what metadata to extract to the sidecar file. Possible are Exif, IPTC and XMP and the default is all of these. .sp 1 - : Output sidecar file to stdout (see -i tgt for example) .sp 1 .TP .B \-r \fIfmt\fP Filename format for the 'rename' action. The format string follows \fBstrftime\fP(3) and supports the following keywords: .br :basename: - original filename without extension .br :dirname: - name of the directory holding the original file .br :parentname: - name of parent directory .br Default filename format is %Y%m%d_%H%M%S. .TP .B \-c \fItxt\fP JPEG comment string to set in the image ('modify' action). This option can also be used with the 'extract' and 'insert' actions to modify metadata on-the-fly. .TP .B \-m \fIfile\fP Command file for the 'modify' action. This option can also be used with the 'extract' and 'insert' actions to modify metadata on-the-fly. .TP .B \-M \fIcmd\fP Command line for the 'modify' action. This option can also be used with the 'extract' and 'insert' actions to modify metadata on-the-fly. The format for the commands is the same as that of the lines of a command file. .TP .B \-l \fIdir\fP Location (directory) for files to be inserted or extracted. .TP .B \-S \fI.suf\fP Use suffix \fI.suf\fP for source files in 'insert' action. .SH COMMANDS Commands for the 'modify' action can be read from a command file, e.g., .sp 1 .nf exiv2 \-m cmd.txt image.jpg .fi .sp 1 or given on the command line, as in .sp 1 .nf exiv2 \-M"add Iptc.Application2.Credit String Mr. Smith" image.jpg .fi .sp 1 Note the quotes. Multiple \fB\-m\fP and \fB\-M\fP options can be combined, and a non-standard XMP namespace registered. .sp 1 .nf exiv2 \-M"reg myprefix http://ns.myprefix.me/" \-M"add Xmp.myprefix.Whom Mr. Smith" \-M"set Exif.Image.Artist Mr. Smith" image.jpg .fi .sp 1 When writing Exif, IPTC and XMP metadata, .B exiv2 enforces only a correct metadata structure. It is possible to write tags with types and values different from those specified in the standards, duplicate Exif tags, undefined tags, or incomplete metadata. While .B exiv2 is able to read all metadata that it can write, other programs may have difficulties with images that contain non standard-conforming metadata. .SS Command format The format of a command is .sp 1 .nf \fBset | add | del\fP \fIkey\fP [[\fItype\fP] \fIvalue\fP] .fi .TP .B set Set the \fIvalue\fP of an existing tag with a matching \fIkey\fP or add the tag. .TP .B add Add a tag (unless \fIkey\fP is a non\-repeatable IPTC key; nothing prevents you from adding duplicate Exif tags). .TP .B del Delete all occurrences of a tag (requires only a \fIkey\fP). .TP .I key Exiv2 Exif, IPTC or XMP key. .TP .I type .B Byte | Ascii | Short | Long | Rational | Undefined | SShort | SLong | SRational | Comment for Exif keys, .br .B String | Date | Time | Short | Undefined for IPTC keys, and .br .B XmpText | XmpAlt | XmpBag | XmpSeq | LangAlt for XMP keys. .sp 1 A default \fItype\fP is used if none is explicitly given. The default is determined based on \fIkey\fP. .TP .I value The remaining text on the line is the value. It can optionally be enclosed in single quotes ('\fIvalue\fP') or double quotes ("\fIvalue\fP"). .sp 1 The value is optional. Not providing any value is equivalent to an empty value ("") and is mainly useful to create an XMP array property, e.g., a bag. .sp 1 The format of Exif \fBComment\fP values includes an optional charset specification at the beginning: .br .B [charset=Ascii|Jis|Unicode|Undefined ]\fIcomment\fP .sp 1 .B Undefined is used by default if the value doesn't start with a charset definition. .sp 1 The format for an IPTC \fBDate\fP value is: .br YYYY\-MM\-DD (year, month, day) .sp 1 The format for an IPTC \fBTime\fP value is: .br HH:MM:SS (hours, minutes, seconds) .br and may optionally be followed by: .br \-HH:MM or +HH:MM (hours, minutes ahead/behind UTC) .sp 1 The format of \fBRational\fP (and \fBSRational\fP) is one of: .br integer .br integer-numerator/integer-denominator .br Fnumber .br fnumber .sp 1 Rational Examples: .br exiv2 "-Mset Exif.Photo.MaxApertureValue 557429/62500" X.jpg .br exiv2 "-Mset Exif.Photo.MaxApertureValue F5.6" X.jpg .sp 1 The Rational format Fnumber (or fnumber) is for the convenience of setting aperture values. Aperture values are stored in Exif is an \fBAPEX\fP value which can be evaluated by the expression: .sp 1 apex-value = log(Fnumber) * 2.0 / log(2.0) .br Fnumber = exp(apex-value * log(2.0) / 2.0) .sp 1 The Rational format Fnumber is valid for any \fBRational\fP, even when the key is not an Aperture. More information about \fBAPEX\fP value is available from: http://en.wikipedia.org/wiki/APEX_system .sp 1 The format of XMP \fBLangAlt\fP values includes an optional language qualifier: .br .B lang="\fIlanguage-code\fP\fI" text\fP .sp lang="x-default" is used if the value doesn't start with a language qualifier. .sp 1 exiv2 -M'set Xmp.dc.title lang="de-DE" Euros' X.jpg .br exiv2 -M'set Xmp.dc.title lang="en-GB" Pounds' X.jpg .br exiv2 -M'set Xmp.dc.title lang="en-US" In God We Trust' X.jpg .br exiv2 -M'set Xmp.dc.title All others pay cash' X.jpg .sp 1 To remove a language specification, set the value to '' (empty string) .br exiv2 -M'set Xmp.dc.title lang="en-US"' X.jpg .sp 1 To remove all language specifications, delete the key: .br exiv2 -M'del Xmp.dc.title' X.jpg .TP To register additional XMP namespaces, combine the command with: .TP .nf \fBreg\fP \fIprefix\fP \fInamespace\fP .fi .SS Command file format Empty lines and lines starting with \fB#\fP in a command file are ignored (comments). Remaining lines are commands as described above. .SH EXAMPLES .TP exiv2 *.jpg Prints a summary of the Exif information for all JPEG files in the directory. .TP exiv2 \-pi image.jpg Prints the IPTC metadata of the image. .TP exiv2 rename img_1234.jpg Renames img_1234.jpg (taken on 13\-Nov\-05 at 22:58:31) to 20051113_225831.jpg .TP exiv2 \-r':basename:_%Y%m' rename img_1234.jpg Renames img_1234.jpg to img_1234_200511.jpg .TP exiv2 \-et img1.jpg img2.jpg Extracts the Exif thumbnails from the two files into img1\-thumb.jpg and img2\-thumb.jpg. .TP exiv2 \-it img1.jpg img2.jpg Inserts (copies) metadata from img1.exv to img1.jpg and from img2.exv to img2.jpg. .TP exiv2 \-ep1,2 image.jpg Extracts previews 1 and 2 from the image to the files image\-preview1.jpg and image\-preview2.jpg. .TP exiv2 \-eiX image.jpg Extracts IPTC datasets into an XMP sidecar file image.xmp and in the process converts them to "IPTC Core" XMP schema. .TP exiv2 \-iixX image.jpg Inserts IPTC and XMP metadata from an XMP sidecar file image.xmp into image.jpg. The resulting IPTC datasets are converted from the "IPTC Core" XMP schema properties in the sidecar file to the older IPTC IIM4 format. The inserted XMP properties include those in the "IPTC Core" XMP schema. .TP .nf exiv2 \-M"set Exif.Photo.UserComment charset=Ascii New Exif comment" image.jpg .fi Sets the Exif comment to an ASCII string. .TP .nf exiv2 \-M"set Exif.GPSInfo.GPSLatitude 4/1 15/1 33/1" \\ \-M"set Exif.GPSInfo.GPSLatitudeRef N" image.jpg .fi Sets the latitude to 4 degrees, 15 minutes and 33 seconds north. The Exif standard stipulates that the GPSLatitude tag consists of three Rational numbers for the degrees, minutes and seconds of the latitude and GPSLatitudeRef contains either 'N' or 'S' for north or south latitude respectively. .TP .nf exiv2 insert \-l/tmp -S.CRW /data/*.JPG .fi Copy all metadata from CRW files in the /tmp directory to JPG files with corresponding basenames in the /data directory. Note that this copies metadata as is, without any modifications to adapt it to the requirements of the target format. Some tags copied like this may not make sense in the target image. .SH SEE ALSO .TP .I http://www.exiv2.org/sample.html#modify Sample command files. .TP .I http://www.exiv2.org/metadata.html Taglists with \fIkey\fP and default \fItype\fP values. .SH AUTHORS .B exiv2 was written by Andreas Huggel and others.
