For sorting the array bubble sort is the simplest technique. Bubble sort works by swapping the adjacent elements if they are in wrong order .
Example:
Given array - (9, 7, 2, 5)
After first iteration - (7, 2, 5, 9)
After second iteration - (2, 5, 7, 9)
and so on...
In this way, the array is sorted by placing the greater element at the end of the array .

# Sorting the array in Bash  
# using Bubble sort \
# Static input of Array 
arr = (10 8 20 100 12) 
echo "Array in original order"
echo ${arr[*]} 
# Performing Bubble sort  
for ((i = 0; i<5; i++)) 
do
    for((j = i; j<5-i-1; j++)) 
    do
        if ((${arr[j]} > ${arr[$((j+1))]})) 
        then
            # swap 
            temp = ${arr[$j]} 
            arr[$j] = ${arr[$((j+1))]}   
            arr[$((j+1))] = $temp 
        fi
    done
done
  
echo "Array in sorted order :"
echo ${arr[*]} 
Output :
Array in sorted order :
8 10 12 20 100
