, there is another frequently used tool to edit exif data: exiftool (

 ). When you execute exiftool to display the exif data, you get a list like this:&lt;code&gt;user@laptop:~$ exiftool IMG_001.jpgExifTool Version Number : 10.80File Name : IMG_001.jpg[…]Date/Time Original : 2018:09:02 13:20:13Create Date : 2018:09:02 13:20:13[…]&lt;/code&gt;However, in order to modify a value you need to address the individual tag and the tag name that the command line expects is NOT the same that is given in the list (the tag for &amp;ldquo;Create Date&amp;rdquo; is e.g. &amp;ldquo;CreateDate&amp;rdquo;):&lt;code&gt;exiftool -CreateDate='2009:11:32 09:11:24.991000' IMG_001.jpg&lt;/code&gt;Exiftool is probably the most capable tool, but for the same reason, it is not the most easy to use.IN order to remove all exif data, try:&lt;code&gt;exiftool -all=IMG_001.jpg&lt;/code&gt;&lt;/p&gt;</description></item></channel></rss>
