How to update issues in bulk from a CSV file using Jira Command Line Interface (CLI)

This article explains how to update issues in bulk from a CSV file using Jira Command Line Interface (CLI).

Instructions

Create a CSV file with the below columns:
- issue refers to the issue key.
- summary is the issue summary.
- description is the issue description.
- priority is the issue priority.
- assignee refers to the issue assignee.
Combine runFromCsv with the --file parameter and updateIssue action to create issues in bulk. This example works because the CSV file contains the data that is required for the updateIssue action with relevant parameters.
```
--action runFromCsv --file updatessues.csv --common "--action updateIssue"
```

Additional columns can be added for custom fields and a list of supported custom fields have been documented in Custom Field Types.
It is recommended to test this scenario in a non-production environment or run the action with the --simulate parameter, to verify the behavior before deploying on a production environment.
