The line "Last metadata expiration check: [...]" is not printed by tail
at all. It is printed by dnf to standard _error_ output. You will see
it even if you redirect dnf's standard output to /dev/null:
$ dnf repoquery --requires bash --recursive --resolve >/dev/null
Last metadata expiration check: [...]
You can use `dnf --quiet ...` to suppress the message.
