Usage

Arguments without any flag works as upsert operation - create new pair if the key does not exist, or update the value of the key if the key does exist.

echo -e "BUCKET=public\nREGION=ap-southeast-1" | kvu TOKEN=348a1912 REGION=eu-north-1
BUCKET=public
REGION=eu-north-1
TOKEN=348a1912

-c/--create Create new pair

Does nothing when the key exists.

BUCKET=public
REGION=ap-southeast-1

-u/--update Update existing pair

Does nothing when the key does not exist.

$ echo -e "BUCKET=public\nREGION=ap-southeast-1" | kvu --update TOKEN=348a1912
