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

This article explains how to add values to five custom fields to issues at once to several issues in bulk, by using Jira Command Line Interface (CLI).

Instructions

Form a JQL query to find the target issue, where the custom field values need to be added. Please refer below sample JQL for reference:
```
project = ABC AND issuetype = Story
```
Using runFromIssueList and updateIssue actions, any number of field values can be updated.
```
--action runFromIssueList --jql "project = ABC AND issuetype = Story" --common "-a updateIssue --issue @issue@ --field "select1=test1" --field "select2=test2" --field "select3=test3" --field "select4=test4" --field "select5=test5""
```
In the above action:
select1, select2, select3, select4, select5 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
If you want the action to be run against a CSV file, make sure the CSV file has the following columns as shown in the below screenshot:

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

Run the action using runFromCsv as shown below:

--action runFromCsv --file "/Users/Downloads/Atlassian/atlassian-cli-9.4.0-SNAPSHOT/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.
