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
Edit: Trying Turn's answer, I did this:
values='{"hello1":"world1","hello1.world1.abc1":"hello2.world2.abc2","testk":"testv"}'
for s in $(echo $values | jq -r "to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]" ); do
export $s
done
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 export
ing 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")[]')
