Is there an easy way to find the lowest and highest number in a set of variables with values? (Bash script) (Linux)

#!/usr/bin/bash
for i in {1..10}
do
      read integer”$i”
done
sum=$((integer1+integer2+integer3+integer4+integer5+integer6+integer7+integer8+integer9+integer10))
echo Sum is $sum

I don’t know how to find the highest/lowest of the 10 variables and output them.

>Solution :

Compute the sum, max and min on the fly, as you would do in any programming language. And prefer an indexed array to store your integers (and access to their value with ${integer[1]}, ${integer[2]},...:

#!/usr/bin/bash
declare -ai integer=()
declare -i max min sum
for i in {1..10}; do
  read integer[i]
  if (( i == 1 )); then
    max="${integer[i]}"
    min="${integer[i]}"
    sum="${integer[i]}"
  else
    (( max = integer[i] > max ? integer[i] : max ))
    (( min = integer[i] < min ? integer[i] : min ))
    (( sum += integer[i] ))
  fi
done
printf 'max is %d\n' "$max"
printf 'min is %d\n' "$min"
printf 'sum is %d\n' "$sum"
