Which command is used for renaming fields in a Splunk search?

The command used for renaming fields in a Splunk search is "rename." This command allows users to change the name of an existing field to a new name within the search results. When you use the rename command, you specify the current field name and the new name you'd like to assign to it. This can be particularly useful for improving the readability of your search results or making the field names more intuitive for your specific analysis needs.

For instance, if you have a field named "src_ip" and you want to change it to "source_ip," you would use the rename command in your search string. This command has the syntax rename source_ip as src_ip, making it very clear and straightforward to implement.

Other commands listed in the options serve different purposes. "Alias" is typically used for creating alternate names for fields but does not change the original field's name. "Transform" refers to a more complex set of functionalities that include modifying the structure or format of data, rather than simply renaming fields. Lastly, "change" is not a recognized command within the context of renaming fields in Splunk. Therefore, the use of the rename command is specific and direct for the task of renaming fields in a Splunk search,
