If I need to rename a file, yeah, I can do that by right-clicking it in the file explorer, and selecting ‘rename’ from the menu. Two files? Painful but doable. Three files? Oh hell no, I’m switching to my always-open-in-background terminal window, and write a quick c=1; for f in *.jpeg; do mv “$f” $c.jpeg; c=expr $c + 1 ; done and it takes twice less time than clicking things through with mouse.
And yes, I wrote that shell command off the top of my head on the first try and without edits.
