@_elena Here's another one.
Supposing you've just downloaded a file, got an output from a programme or summat.
ls -ltr
There "l" does what you already know.
The "t" orders the list in time (created or last modified), and the "r" puts the list in reverse order so the last saved file is there at the foot of he list, conveniently just above your prompt.
I use this a lot, it's so "baked in" to my fingers over so many years that I type it without thinking about it.
