Example 1. Invoke neo4j-admin database info against a database store
bin/neo4j-admin database info healthcare
Output
Database name:                healthcare
Database in use:              false
Store format version:         block-block-1.1
Store format introduced in:   5.14.0
Last committed transaction id:29
Store needs recovery:         false
Example 2. Invoke neo4j-admin database info against all databases
bin/neo4j-admin database info --from-path=../data/databases
Output
Database name:                healthcare
Database in use:              false
Store format version:         block-block-1.1
Store format introduced in:   5.14.0
Last committed transaction id:29

If you are parsing the results of this command, you may use the --format=json option to receive the output as JSON. All the same fields are included and all values are strings.

bin/neo4j-admin database info --from-path ../data/databases --format=json foo
Output
{"databaseName":"healthcare","inUse":"false","storeFormat":"block-block-1.1","storeFormatIntroduced":"5.14.0","storeFormatSuperseded":null,"lastCommittedTransaction":"29","recoveryRequired":"false"}
