You can combine commands. The pipe ( | ) character is used to separate the syntax of one command from the next command.

The following example reads from the main dataset and then pipes that data to the eval command. You use the eval command to calculate an expression. The results of that expression are placed into a field in the search results that are returned to you.

This search takes the data in the bytes field in the main dataset and converts the bytes into kilobytes. The results are stored in a new field called kbytes.

| from main | eval kbytes = bytes / 1024
