How to add values to 5 custom fields to issues in bulk using Jira Command Line Interface (CLI)

This article explains how to add values to five custom fields to multiple issues in bulk using Jira Command Line Interface (CLI).

Instructions

Create a JQL query to find the target issue(s), where the custom field values need to be added. Refer to the following:
```
project = ABC AND issuetype = Story
```
Use runFromIssueList and updateIssue actions to update any number of field values.
```
--action runFromIssueList --jql "project = ABC AND issuetype = Story" --common "-a updateIssue --issue @issue@ --field "field1=test1" --field "field2=test2" --field "field3=test3" --field "field4=test4" --field "field5=test5""
```
In the above action: field1, field2, field3, field4, field5 are the text type custom fields and test1, test2, test3, test4, test5 are the corresponding values of the fields.
--jql for the JQL query
--issue takes the issue key
--field accepts the custom field ID or name

To run the action against a CSV file, make sure the CSV file has the following columns as the following:

In the above screenshot, field1, field2, field3, field4, field5 are the custom field names.

Run the action using runFromCsv as the following:

--action runFromCsv --file "filename.csv" --common "--action updateIssue"

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 implementing it in production.
