The given command is a loop command that retrieves information about multiple DNS zones using the Flare CLI tool, specifically the flarectl command.

Here's a breakdown of what each component does:

1. for domain in $(cat ${domains-txt}); do ... ; done: This starts a loop that iterates over each line in the ${domains-txt} file, where each line represents a domain. The domain variable will be set to each domain one by one as the loop iterates.

2. flarectl zone info --zone=$domain: This is the command executed inside the loop. It requests information about a DNS zone using the flarectl command with the zone info option. The --zone=$domain specifies the domain (retrieved from the loop variable) for which information is being fetched.

In summary, the loop reads each line from the ${domains-txt} file, sets the domain variable to that line, and then executes the flarectl zone info command with the respective domain. This way, it retrieves the zone information for each domain listed in ${domains-txt}.
