In a folder with a single file (image.jpg) I run the following commands
$ ls -a
. .. image.jpg
$ tar cf target.tar image.jpg
Listing contents of the archive
$ tar tvf target.tar
-rwxrwxrwx 0 Oskar staff 190 8 Feb 12:14 ./._image.jpg
-rwxrwxrwx 0 Oskar staff 404968 8 Feb 12:14 image.jpg
Extracting archive
$ tar xzf target.tar
$ ls -a
. .. image.jpg target.tar
Why does the list of files in the archive show two files?
I'm running this in OSX 10.11.5.
$ tar --version
bsdtar 2.8.3 - libarchive 2.8.3
Extracting the same archive in Python using Tarfile.extractall() also extracts the ./._image.jpg file.
I've only seen this happen with .jpg files, .txt and .xml files works as expected.
