ExifTool by Phil Harvey (philharvey66 at gmail.com)

ExifTool is a customizable set of Perl modules plus a full-featured command-line application for reading and writing meta information in a wide variety of files, including the maker note information of many digital cameras by various manufacturers such as Canon, Casio, DJI, FLIR, FujiFilm, GE, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Nikon, Nintendo, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Phase One, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon and Sony.

Below is a list of file types and meta information formats currently supported by ExifTool (r = read, w = write, c = create):

RUNNING

The exiftool script can be run right away without the need to install Image::ExifTool. For example, from within the exiftool directory you can extract the information from one of the included test files by typing:

./exiftool t/images/ExifTool.jpg

If you move the exiftool script to a different directory, you must also either move the contents of the lib directory or install the Image::ExifTool package so the script can find the necessary libraries.

Note: If you are using the Windows cmd shell, you may need to rename 'exiftool' to 'exiftool.pl' to run it directly from the command line. Alternatively, you can run exiftool with the command 'perl exiftool'.

IF YOU ARE STILL CONFUSED

The exiftool script is a command line application. You run it by typing commands in a terminal window. The first step is to determine the name of the directory where you downloaded the ExifTool distribution package. Assuming, for example, you downloaded it to a folder called "Desktop" in your home directory, then you would type the following commands in a terminal window to extract and run ExifTool:

cd ~/Desktop gzip -dc Image-ExifTool-13.59.tar.gz | tar -xf - cd Image-ExifTool-13.59 ./exiftool t/images/ExifTool.jpg

Note: These commands extract meta information from one of the test images. To use one of your images instead, enter the full path name of your file in place of "t/images/ExifTool.jpg".

INSTALLATION

You can install the Image::ExifTool package to make it available for use by other Perl scripts by typing the following:

perl Makefile.PL make make test make install

Notes: i) You need root access for the last step above.

ii) Some Perl installations (like the standard OSX installation) may not contain the necessary files to complete the first step above. But no worries: You can install ExifTool manually by moving 'exiftool' and the 'lib' directory to any directory in your current PATH (ie. /usr/bin).

iii) In Windows, "dmake" or "nmake" may be used if "make" is not available.

(Also see html/install.html for more help with installation.)

DEPENDENCIES

Requires Perl version 5.004 or later. No other special libraries are required, however the following modules are recommended for decoding compressed and/or encrypted information from the indicated file types, and for calculating digest values and providing other features listed below:

Archive::Zip (ZIP, DOCX, PPTX, XLSX, ODP, ODS, ODT, EIP, iWork) Compress::Zlib (DNG, PNG, PDF, DCM, MIE and SWF files) Digest::MD5 (PDF files, IPTC information, and JPG Extended XMP) Digest::SHA (PDF with AES-256 encryption) IO::Compress::Bzip2 (RWZ files) Time::HiRes (for generating ProcessingTime tag) POSIX::strptime (for inverse date/time conversion) Time::Piece (alternative to POSIX::strptime) Unicode::LineBreak (for column alignment of alternate-language output) Win32::API (for proper handling of Windows file names/times) Win32::FindFile (for Windows Unicode directory support, app only) Win32API::File (for Windows Unicode file names and file times) File::StatX (for reading FileCreateDate on Linux systems) Compress::Raw::Lzma (for reading encoded 7z files) IO::Compress::RawDeflate (for writing FLIF images) IO::Uncompress::RawInflate (for reading FLIF images) IO::Compress::Brotli (for writing compressed JXL metadata) IO::Uncompress::Brotli (for reading compressed JXL metadata)

and if you have installed Image::ExifTool, you can also consult perldoc or the man pages:

perldoc exiftool perldoc Image::ExifTool perldoc Image::ExifTool::TagNames

man exiftool man Image::ExifTool man Image::ExifTool::TagNames

Note: If the man pages don't work, it is probably because your man path is not set to include the installed documentation. See "man man" for information about how to set the man path.
