As shared by Robert [1], the command to retrieve the serial number is as 
follows: 

sudo hexdump -e '8/1 "%c"' /sys/bus/i2c/devices/0-0050/eeprom -n 28 | 
cut -b 5-28 

Is there anyway to get the serial number without using sudo? My use case is 
that I wish to let other programs use the serial number, but I do not wish 
for these progams to have sudo privilege. What are the possible approaches?
