need shell script to sort numbers including decimal numbers

Question

(This question already has answers here): question from:https://stackoverflow.com/questions/66059690/need-shell-script-to-sort-numbers-including-decimal-numbers

Answer 1

i want the list to be as follow: -20 1.2 8 10 100

1. Output numbers one per line.
2. Sort
3. Join with space

$ arr=(10 8 -20 100 1.2)
$ printf "%s
" "${arr[@]}" | sort -g | paste -sd' '
-20 1.2 8 10 100

Don't reimplement sort using shell - it's going to be incredibly slow. The -g option to sort may not be available everywhere - it's for sorting floating point numbers.

[: 1.2: integer expression expected Array

The [ command handles integers only. 1.2 has a comma, [ can't handle it. Use another tool. Preferable python.

${arr[$((j+1))]}

No need to use $(( - stuff inside [ is already expanded arithmetically. Just ${arr[j+1]}.

j<5-i-1

is strange condition. When i=4 then it's j<0 and loop will not run at all. Just iterate from i instead of up to i - ((j=i;j<5;++j)).

echo "Array in sorted order :" echo ${arr[*]}

Will print echo to output. Just echo "Array in sorted order : ${arr[*]}" or echo "Array in sorted order :" "${arr[@]}"
