Chapter 7. Batch Processing
Batch processing allows multiple operation requests to be grouped in a sequence and executed together as a unit. If any of the operation requests in the sequence fail, the entire group of operations is rolled back.
Batch mode does not support conditional statements.
Enter batch mode with the
batchmanagement CLI command.batch
Batch mode is indicated by the hash symbol (
#) in the prompt.Add operation requests to the batch.
Once in batch mode, enter operation requests as normal. The operation requests are added to the batch in the order they are entered.
You can edit and reorder batch commands. You can also store a batch for processing at a later time. See Batch Mode Commands for a full list of commands available for working with batches.
Run the batch.
Once the entire sequence of operation requests is entered, run the batch with the
run-batchcommand.run-batch
The entered sequence of operation requests is completed as a batch and prints the result to the terminal:
The batch executed successfully.
Batch Commands in External Files
Frequently-run batch commands can be stored in an external text file and can be loaded either by passing the full path to the file as an argument to the batch command or executed directly by being passed as an argument to the run-batch command.
You can create a batch command file by using a text editor and placing each command on its own line.
The following command will load the myscript.txt file in batch mode. The commands from this file can then be edited or removed. New commands can be inserted. Changes made in this batch session do not persist to the myscript.txt file.
batch --file=myscript.txt
The following will immediately run the batch commands stored in the file myscript.txt
run-batch --file=myscript.txt
The entered sequence of operation requests is completed as a batch.
