Listing partitions names and mount points

I'm trying to get list of partitions and their mount points in terminal, but I'm not so succesfull. "ls -l /dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/” (found this path by using "cat /proc/mounts" but it return me a 'permission denied, I guess I need root, but I don't have one. So how to get partitions names and mount points without root? Also there is one weird thing: when I go with Total commander in /dev folder there isn't /block folder inside just file named 'block' with size 0 and not readable (becase lack of root). How is that possible?
