Laas's questions

I recently installed QupZilla, but the speed dial won't work. When I try to add a new page it adds the sign but shows "unable to load". It is not only unable to load the title and preview picture (there are reports about that issue on win and mac), but it doesn't take the url regardless of the webpage I insert (I tried several). I opened it in a terminal in the hope that it gives me an error message, but it didn't.

Does anyone have an idea what the problem might be? I'm completely at a loss.

Ubuntu: 16.04.1
QupZilla: 1.8.9
WebKit: 538.1

EDIT:
I didn't see that it is possible to add new pages to the speed-dial via the "bookmark this page"-function. This doesn't solve the problem but at least it's possible to use the speed-dial now.

I just started my journey into bash scripting and I wrote a little script which copies certain files to my USB stick and external harddrive as a backup. So far it copies the entire directory with all files including those which I didn't change which naturally takes quite some time. In order to change that, I want it to compare the two files (on the pc and on the USB stick) with regards to the time when they were modified. So now I wonder how I can convert the output from

stat -c %y /test_folder/test.txt

into the format "YmDHMS"? Or maybe someone knows a better way to compare the files.
