Command and Batch Processing
As of version 2.9, Picard will try to only run a single instance of the program at a time.
When the program is started, it checks to see if there is another instance of that version,
configuration file and plugin startup status
-P already running. If the same version
is already running, any files or directories specified on the command line of the new
instance, along with any executable commands specified with the
will be passed to the already running instance for processing and the new duplicate instance
will be shut down. This allows batch processing of files to be initiated automatically from
other processes. If there is no instance of that version already running, Picard will start
For example if there is an instance of Picard running and a second instance is started with the command line:
picard -e load mbid://release/dbd0ce67-cae6-33eb-8f5a-1143a30c2353
the load command will be passed to the running instance to load the specified release, and the second instance will be closed.
This allows the user to set up dynamic batch processing of commands to automate the tagging
process, especially when used with the
FROM_FILE command to load a standard processing
command sequence such as:
CLUSTER LOOKUP_CLUSTERED SAVE_MATCHED REMOVE_SAVED REMOVE_EMPTY
LOOKUP_CD path/to/ripper.log SAVE_MATCHED FINGERPRINT SUBMIT_FINGERPRINTS REMOVE_SAVED REMOVE_EMPTY
or even something like:
# Load a directory of files to process LOAD path/to/directory/of/unprocessed/files # Try clustering and lookup the clusters first CLUSTER LOOKUP_CLUSTERED # Save matched clusters SAVE_MATCHED # Calculate and submit fingerprints for the matched files FINGERPRINT SUBMIT_FINGERPRINTS # Clean up and remove the saved files REMOVE_SAVED REMOVE_EMPTY # Try scanning the remaining files to find matches SCAN # Save matched files from the scans SAVE_MATCHED # Clean up and remove the saved files REMOVE_SAVED REMOVE_EMPTY # Any files remaining in the cluster pane could not be # matched automatically
