Shell------randomly generate three-digit numbers

write a script to generate a random 3-bit number, and can be based on the user's input parameters to determine the output of a few groups. For example, the script name is number3.sh.
Execution Method:
Bash 2.sh
produces a set of 3-digit numbers directly.
Bash 2.sh
plug in 10 groups of 3 digits.

idea: You can use the Echo $RANDOM to get a random number, then divide by 10, take the remainder to get 0-9 random numbers, and get a set of three operations.
