Also, it makes easier to correct wrong metadata quickly. Luckily, one strategy doesn’t preclude the other.Įmbedding metadata inside pictures with command-line tools has two great advantages: it may be much faster than working with GUI-based tools, especially when working with many files that never had metadata associated with them, such as scanned photos of your grandfather’s graduation.
EXIFTOOL DEBIAN ARCHIVE
You can be sure the metadata will always remain associated with the image and that nobody will have to manually enter it again, even if you change your picture management software, archive your pictures on DVDs, or give away copies to friends.
EXIFTOOL DEBIAN PORTABLE
On the other hand, storing as many metadata tags as possible inside the picture file they refer to is a much more portable solution. Where should metadata be stored, in some centralized database or inside each file? The first is more efficient if you have large numbers of digital pictures you want to search in many different ways. Several options allow recursive operations inside directory trees. By default a separate copy of the original file is saved with the “_original” suffix. You just need to type exiftool and then the name (prepended by a dash) and value of each EXIF tag to write. The basic syntax to add or modify EXIF tags is simple. So, for instance, to save a local, commented copy of a JPEG picture you found online, you can use a command like wget -qO - | exiftool -Comment="African Sunset" > localcopy.jpg. The utility can read and write data and pictures from pipes or (remote) files without any problem.
EXIFTOOL DEBIAN PLUS
It comprises a multiplatform bundle of some Perl modules for EXIF processing plus a small program called exiftool to use them from the command line.
EXIFTOOL DEBIAN HOW TO
In this article we’ll see how to use ExifTool to manage EXIF data inside JPEG files.ĭue to its architecture, ExifTool is very flexible. ExifTool is an efficient, flexible, and portable way to manage image, audio, and video metadata under Linux. For additional help or useful information, we recommend you check the official ExifTool website.Digital media files are more useful and accessible when tagged with metadata - that is, descriptive information about each photo that either can be embedded inside images themselves or stored in external databases. Thanks for using this tutorial for installing the latest version of the ExifTool on the Linux Mint system.
