When you do, your phone may store the picture and embed a metadata tag in the picture named Flash. For example, perhaps you take a picture with your phone. Tags are key-value pairs embedded into files that store information about that file. Tags are extremely important to understand as nearly everything in exiftool comes back to metadata tags in some way. Metadata is stored in these files as metadata tags or just tags. Metadata is information embedded into documents and media that are typically hidden from view.
DEBIAN EXIFTOOL HOW TO
Translating Tags into Different Languagesīefore you can understand how to use exiftool, you must understand metadata.Filtering with If/Then Conditional Logic.Exporting Tag Lists to CSV, HTML, JSON, and More.Displaying Only Tags in a Specific Group.Managing Duplicate Tag Names in Different Groups.Reading Metadata with ExifTool: A Simple Example.# remove metedata for all *gif/*GIF files in current dir and subdirsĮxiftool -all= -r -overwrite_original -ext gif. # remove metedata for all *bmp/*BMP files in current dir and subdirsĮxiftool -all= -r -overwrite_original -ext bmp. # remove metedata for all *png/*PNG files in current dir and subdirsĮxiftool -all= -r -overwrite_original -ext png. # remove metedata for all *jpg/*JPG files in current dir and subdirsĮxiftool -all= -r -overwrite_original -ext jpg. # remove all metadata of all *jpg files in current dirĮxiftool -all= -overwrite_original -ext jpg.

“Improper neutralization of user data in the DjVu file format in ExifTool versions 7.44 and up allows arbitrary code execution when parsing the malicious image” ( src CVE-2021-22204) It is remarkable, that even the most simple tool, like exiftool seems to have (had?) a serious security problem: GNU Linux (Debian 10) – how to show and remove all (privacy intrusive) meta Exif meta info from jpg png tiff bmp pictures and now even mp4! :) Volunteer computing / World Community Grid / WCG.Virtualization / KVM / VirtualBox / xenserver.USV / UPS / Power / PowerSupply / Energie.Space / Cosmos / Kosmos / Galaxy / Galaxie / Weltall.raspberry / carambola / atmel / embedded linux.
