Liquibase provides an update command, which executes all the ChangeSets in a ChangeLog file. To verify the executed ChangeSets, Liquibase provides a history command that lets the DBA inspect the history of all the ChangeSets to ensure they have been executed successfully.
The history command will list all the deployed ChangeSets along with its deploymentId
