The way to do this is discussed on the exiv2 forum: http://dev.exiv2.org/boards/3/topics/901 You combine the separate options
For example: ~/image.tests$ exiv2 -qpa blank.jpg Results in no output, but: ~/image.tests$ exiv2 -q pa blank.jpg pa: Failed to open the file blank.jpg File name : blank.jpg blank.jpg File size : 4691 Bytes blank.jpg MIME type : image/jpeg blank.jpg Image size : 229 x 83 blank.jpg: No Exif data found in the file ** Changed in: exiv2 (Ubuntu) Status: New => Invalid ** Changed in: exiv2 (Ubuntu) Assignee: (unassigned) => Alan Pater (alan-pater) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to exiv2 in Ubuntu. https://bugs.launchpad.net/bugs/1398251 Title: Options "-q" and "-Qm" not making quiet Status in exiv2 package in Ubuntu: Invalid Bug description: The option "-q" and "-Qm" should both suppress error messages. Both do not prevent the message "No Exif data found in the file", which is shown on stderr when there are no such data: $ exiv2 -Qm pr test.jpg File name : test.jpg File size : 241565 Bytes MIME type : image/jpeg Image size : 2338 x 1654 test.jpg: No Exif data found in the file (Same result for "exiv2 -q pr test.jpg") Option "-q" is described as "Silence warnings and error messages from the Exiv2 library...". Even though it's not obvious whether the message above is strictly from the library or from the "exiv2" tool using the library, the description makes me expect the message would be suppressed. Option "-Qm" is setting the log level (of the tool, I suppose) to "mute" - which should clearly suppress the message. Also, the description notes "-Qm is equivalent to -q" - implying that "-q" should also mute.
