Exporting JSON to environment variables

Question

If I have a JSON like this,

{     "hello1": "world1",     "testk": "testv" } 

And I want to export each of these key-value pairs as environment variables, how to do it via shell script? So for example, when I write on the terminal, echo $hello1, world1 should be printed and similarly for other key-value pairs? Note: The above JSON is present in a variable called $values and not in a file.

I know it will be done via jq and written a shell script for this, but it doesn't work.

for row in $(echo "${values}" | jq -r '.[]'); do     -jq() {         echo ${row} | jq -r ${1}     }     echo $(_jq '.samplekey') done 

Answer 1

Borrowing from this answer which does all of the hard work of turning the JSON into key=value pairs, you could get these into the environment by looping over the jq output and exporting them:

for s in $(echo $values | jq -r "to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]" ); do     export $s done 

If the variables being loaded contain embedded whitespace, this is also reasonable, if slightly more complex:

while read -rd $'' line do     export "$line" done < <(jq -r <<<"$values" \          'to_entries|map("\(.key)=\(.value)\u0000")[]')
