SYNOPSIS

       exiv2 [options] [action] file ...

DESCRIPTION

       exiv2  is a program to read and write Exif, IPTC and XMP image metadata

       and image comments. The following image formats are supported:

       Type   Exif         IPTC         XMP          Image comments

       o Support for GIF, TGA and BMP images is minimal: the image  format  is

         recognized,  a  MIME  type assigned to it and the height and width of

         the image are determined.

       o Reading other TIFF-like RAW image formats, which are  not  listed  in

         the table, may also work.

ACTIONS

       The  action  argument  is  only  required  if  it is not clear from the

       options which action is implied.

       pr | print

              Print image metadata. This is the default action, i.e., the com-

              mand  exiv2  image.jpg  will  print  a summary of the image Exif

              metadata.

       ex | extract

              Extract metadata to *.exv, XMP  sidecar  (*.xmp)  and  thumbnail

              image files.  Modification commands can be applied on-the-fly.

       in | insert

              Insert  metadata  from  corresponding *.exv, XMP sidecar (*.xmp)

              and thumbnail files.  Use option -S .suf 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.

       rm | delete

              Delete image metadata from the files.

       ad | adjust

              Adjust Exif timestamps by the given time. Requires at least  one

              of the options -a time, -Y yrs, -O mon or -D day.

       mo | modify

              Apply  commands  to modify (add, set, delete) the Exif, IPTC and

              XMP metadata of image files. Requires option -c, -m or -M.

       mv | rename

              Rename files and/or set file timestamps according  to  the  Exif

              create timestamp. Uses the value of tag Exif.Photo.DateTimeOrig-

              inal or, if not present, Exif.Image.DateTime  to  determine  the

              timestamp. The filename format can be set with -r fmt, timestamp

              options are -t and -T.

       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 stan-

              dard Exif ISO tag.

       fc | fixcom

              Fix  the  character  encoding  of  Exif  Unicode  user comments.

              Decodes the comment using the auto-detected or specified charac-

              ter encoding and writes it back in UCS-2. Use option -n to spec-

              ify the current encoding of the comment if necessary.

OPTIONS

       -h     Display help and exit.

       -V     Show the program version and exit.

       -v     Be verbose during the program run.

       -q     Silence warnings and error messages from the Exiv2 library  dur-

              ing  the program run (quiet). Note that options -v and -q can be

              used at the same time.

       -Q lvl Set the log-level to 'd'(ebug), 'i'(nfo), 'w'(arning), 'e'(rror)

              or  'm'(ute). The default log-level is 'w'. -Qm is equivalent to

              -q. All log messages are written to standard error.

       -b     Show large binary values (default is to suppress them).

       -u     Show unknown tags (default is to suppress tags which don't  have

              a name).

       -g key Only  output info for this Exiv2 key (grep). Multiple -g options

              can be used to grep info for several keys.

       -n enc Charset to use to decode Exif Unicode user comments.  enc  is  a

              name understood by iconv_open(3), e.g., 'UTF-8'.

       -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.

       -t     Set the file timestamp according to the Exif create timestamp in

              addition to renaming the file (overrides  -k).  This  option  is

              only used with the 'rename' action.

       -T     Only  set  the file timestamp according to the Exif create time-

              stamp, do not rename the file (overrides  -k).  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.

       -f     Do  not  prompt  before  overwriting existing files (force over-

              write).

       -F     Do not prompt before renaming files (Force rename). Appends '_1'

              ('_2', ...) to the name of the new file.

       -a time

              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 sec-

              onds.

       -Y yrs Time adjustment by a positive or negative number of  years,  for

              the 'adjust' action.

       -O mon Time  adjustment by a positive or negative number of months, for

              the 'adjust' action.

       -D day Time adjustment by a positive or negative number  of  days,  for

              the 'adjust' action.

       -p mode

              Print mode for the 'print' action. Possible modes are:

              s : print a summary of the Exif metadata (the default)

              a : print Exif, IPTC and XMP metadata (shortcut for -Pkyct)

              t : interpreted (translated) Exif tags (-PEkyct)

              v : plain Exif tag values (-PExgnycv)

              h : hexdump of the Exif data (-PExgnycsh)

              i : IPTC datasets (-PIkyct)

              x : XMP properties (-PXkyct)

              c : JPEG comment

              p  : list available image previews, sorted by preview image size

              in pixels

       -P flgs

              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:

              E : include Exif tags in the list

              I : IPTC datasets

              X : XMP properties

              x : print a column with the tag number

              g : group name

              k : key

              l : tag label

              n : tag name

              y : type

              c : number of components (count)

              s : size in bytes

              v : plain data value

              t : interpreted (translated) data

              h : hexdump of the data

       -d tgt Delete target(s) for the 'delete' action. Possible targets are:

              a : all supported metadata (the default)

              e : Exif section

              t : Exif thumbnail only

              i : IPTC data

              x : XMP packet

              c : JPEG comment

       -i tgt Insert target(s) for the 'insert' action. Possible  targets  are

              the same as those for the -d option, plus a modifier:

              X  :  Insert  metadata  from an XMP sidecar file <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.

              Only JPEG thumbnails can be inserted (not TIFF thumbnails), they

              need to be named file-thumb.jpg.

       -e tgt Extract target(s) for the 'extract' action. Possible targets are

              the  same  as  those for the -d option, plus a target to extract

              preview images and a modifier to generate an XMP sidecar file:

              p[<n>[,<m> ...]] : 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 -pp.

              X  :  Extract  metadata  to  an XMP sidecar file <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.

       -r fmt Filename format for the 'rename' action. The format string  fol-

              lows strftime(3) and supports the following keywords:

              :basename:   - original filename without extension

              :dirname:    - name of the directory holding the original file

              :parentname: - name of parent directory

              Default filename format is %Y%m%d_%H%M%S.

       -c txt 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.

       -m file

              Command  file  for  the 'modify' action. This option can also be

              used with the 'extract' and 'insert' actions to modify  metadata

              on-the-fly.

       -M cmd 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.

       -l dir Location (directory) for files to be inserted or extracted.

       -S .suf

              Use suffix .suf for source files in 'insert' action.

COMMANDS

       Commands for the 'modify' action can be read from a command file, e.g.,

          exiv2 -m cmd.txt image.jpg

       or given on the command line, as in

          exiv2 -M"add Iptc.Application2.Credit String Mr. Smith" image.jpg

       Note the quotes. Multiple -m and -M options can be combined.

       When writing Exif, IPTC and XMP metadata, 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 exiv2 is able to read all

       metadata  that  it can write, other programs may have difficulties with

       images that contain non standard-conforming metadata.

   Command format

       The format of a command is

       set | add | del key [[type] value]

       set    Set the value of an existing tag with a matching key or add  the

              tag.

       add    Add a tag (unless key is a non-repeatable IPTC key; nothing pre-

              vents you from adding duplicate Exif tags).

       del    Delete all occurrences of a tag (requires only a key).

       key    Exiv2 Exif, IPTC or XMP key.

       type   Byte | Ascii | Short | Long | Rational | Undefined  |  SShort  |

              SLong | SRational | Comment for Exif keys,

              String | Date | Time | Short | Undefined for IPTC keys, and

              XmpText | XmpAlt | XmpBag | XmpSeq | LangAlt for XMP keys.

              A  default type is used if none is explicitly given. The default

              is determined based on key.

       value  The remaining text on the line is the value. It  can  optionally

              be   enclosed  in  single  quotes  ('value')  or  double  quotes

              ("value").

              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.

              The format of Exif Comment values includes an  optional  charset

              specification at the beginning:

              [charset=Ascii|Jis|Unicode|Undefined ]comment

              Undefined  is  used by default if the value doesn't start with a

              charset definition.

              The format for IPTC Date  values  is  YYYY-MM-DD  (year,  month,

              day),  that  for  IPTC  Time  values  is HH:MM:SS+|-HH:MM, where

              HH:MM:SS refers to local hour, minute and seconds  and  +|-HH:MM

              refers  to  hours  and minutes ahead or behind Universal Coordi-

              nated Time (+|- means either a + or a - sign is required).

              The format of XMP LangAlt values includes an  optional  language

              qualifier:

              [lang=language-code ]text

              x-default  is  used by default if the value doesn't start with a

              language qualifier.

       An additional command is available to register XMP namespaces:

       reg prefix namespace

   Command file format

       Empty lines and lines starting with # in a  command  file  are  ignored

       (comments). Remaining lines are commands as described above.

EXAMPLES

       exiv2 *.jpg

              Prints  a  summary of the Exif information for all JPEG files in

              the directory.

       exiv2 -pi image.jpg

              Prints the IPTC metadata of the image.

       exiv2 rename img_1234.jpg

              Renames  img_1234.jpg  (taken  on  13-Nov-05  at  22:58:31)   to

              20051113_225831.jpg

       exiv2 -r':basename:_%Y%m' rename img_1234.jpg

              Renames img_1234.jpg to img_1234_200511.jpg

       exiv2 -et img1.jpg img2.jpg

              Extracts   the   Exif   thumbnails   from  the  two  files  into

              img1-thumb.jpg and img2-thumb.jpg.

       exiv2 -it img1.jpg img2.jpg

              Inserts (copies) metadata from img1.exv  to  img1.jpg  and  from

              img2.exv to img2.jpg.

       exiv2 -ep1,2 image.jpg

              Extracts previews 1 and 2 from the image to the files image-pre-

              view1.jpg and image-preview2.jpg.

       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.

       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.

       exiv2 -M"set Exif.Photo.UserComment charset=Ascii New Exif comment" image.jpg

              Sets the Exif comment to an ASCII string.

       exiv2 -M"set Exif.GPSInfo.GPSLatitude 4/1 15/1 33/1" \

              -M"set Exif.GPSInfo.GPSLatitudeRef N" image.jpg

              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.

       exiv2 insert -l/tmp -S.CRW /data/*.JPG

              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.
