Before uploading a photo or image to a forum, I may typically strip the metadata to remove identifying material with
exiftool. The thing is, the Linux file system itself seems to leave some metadata on a file:
cardamom@pluto ~ $ ls -la insgesamt 1156736 drwx------ 145 cardamom cardamom 20480 Mär 16 08:58 . drwxr-xr-x 9 root root 4096 Apr 21 2021 .. -rw-r--r-- 1 cardamom cardamom 123624 Mai 24 2018 IMG_20200627_215609.jpg
So I feel tempted to change the user and group of a file as well. Is that a good idea? There is always a user called
nobody and a group called
nogroup who look like they were almost made for the purpose.
Is that everything or is there more metadata that Linux is leaving on its files?
