The Thunar bulk renamer is relatively good, but recently I wanted to name images based on the capture date. Probably very tedious without the right GUI tool, while it’s just one line using exiftool in the terminal. (I don’t know it off the top of my head)
Similarly, I just extracted the audio only from a video using ffmpeg in like 10s. ffmpeg -i video.mkv -c:a copy out.mka
