linux. how to get images from a (short) video

You can use this code:

ffmpeg -i [nameofthevideo] -r 10 -f image2 image-%3d.jpeg

where 10 after -r is the number of images per second. So you can change it, according to your needs.

linux: keep open the terminal

you can add at the end of your command ;bash
for example:
rclone sync mega:ebooks /mnt/zippati/ebooks/ebooks/ -l -v ;bash

alternative browsers

I'm very disappointed by Midori and Epiphany: too minimalist.
