2.8.9.2.6. Listing Options

-v — Displays verbose output, such as the number of packets and bytes each chain has processed, the number of packets and bytes each rule has matched, and which interfaces apply to a particular rule.

-x — Expands numbers into their exact values. On a busy system, the number of packets and bytes processed by a particular chain or rule may be abbreviated to Kilobytes, Megabytes, or Gigabytes. This option forces the full number to be displayed.

-n — Displays IP addresses and port numbers in numeric format, rather than the default hostname and network service format.

--line-numbers — Lists rules in each chain next to their numeric order in the chain. This option is useful when attempting to delete the specific rule in a chain or to locate where to insert a rule within a chain.

-t <table-name> — Specifies a table name. If omitted, defaults to the filter table.
