Output JSON from Bash script

Question

So I have a bash script which outputs details on servers. The problem is that I need the output to be JSON. What is the best way to go about this?

Answer 1

I'm not a bash-ninja at all, but I wrote a solution, that works perfectly for me. So, I decided to share it with community.

First of all, I created a bash script called json.sh

arr=();

while read x y; 
do 
    arr=("${arr[@]}" $x $y)
done

vars=(${arr[@]})
len=${#arr[@]}

printf "{"
for (( i=0; i

And now I can easily execute it:

$ echo key1 1 key2 2 key3 3 | ./json.sh
{"key1":1, "key2":2, "key3":3}
