dataset update COLLECTION_NAME KEY
update will replace a JSON document in a dataset collection for a given KEY. By default the JSON document is read from standard input but you can specific a spefic file with the “-input” option. The JSON document should aready exist in the collection when you use update.
In this example we assume there is a JSON document on local disc
named jane-doe.json. It contains {"name":"Jane Doe"}
and the
KEY is “jane.doe”. In the first one we specify the full JSON document
via the command line after the KEY. In the second example we read the
data from jane-doe.json. Finally in the last we read the JSON
document from standard input and save the update to “jane.doe”.
The collection name is “people.ds”.
dataset update people.ds jane.doe '{"name":"Jane Doiel"}'
dataset update people.ds jane.doe jane-doe.json
dataset update -i jane-doe.json people.ds jane.doe
cat jane-doe.json | dataset update people.ds jane.doe
