Shell command: ip

OBJECT

`address`	protocol (IP or IPv6) address on a device.
`addrlabel`	label configuration for protocol address selection.
`l2tp`	tunnel ethernet over IP (L2TPv3).
`link`	network device.
`maddress`	multicast address.
`monitor`	watch for netlink messages.
`mptcp`	manage MPTCP path manager.
`mroute`	multicast routing cache entry.
`mrule`	rule in multicast routing policy database.
`neighbour`	manage ARP or NDISC cache entries.
`netns`	manage network namespaces.
`ntable`	manage the neighbor cache's operation.
`route`	routing table entry.
`rule`	rule in routing policy database.
`tcp_metrics/tcpmetrics`	manage TCP Metrics
`token`	manage tokenized interface identifiers.
`tunnel`	tunnel over IP.
`tuntap`	manage TUN/TAP devices.
`vrf`	manage virtual routing and forwarding devices.
`xfrm`	manage IPSec policies.

Objects can be abbreviated (for example addr or a instead of address).

OPTIONS

`-V`	`-Version`		Print the version of the ip utility and exit.
`-h`	`-human`, `-human-readable`		Print statistics with human readable values followed by suffix (compare `ls -h`)
`-b`	`-batch`	`filename`	Read commands from provided file or standard input and invoke them. First failure will cause termination of ip.
	`-force`		Don't terminate ip on errors in batch mode. If there were any errors during execution of the commands, the application return code will be non zero.
`-s`	`-stats`, `-statistics`		print more information. If the option appears twice or more, the amount of information increases. As a rule, the information is statistics or some time values.
`-d`	`-details`		Output more detailed information.
`-l`	`-loops`	`<COUNT>`	Specify maximum number of loops the 'ip address flush' logic will attempt before giving up. The default is 10. Zero (0) means loop until all addresses are removed.
`-f`	`-family`	`<FAMILY>`	Specifies the protocol family to use. The protocol family identifier can be one of inet, inet6, bridge, mpls or link. If this option is not present, the protocol family is guessed from other arguments. If the rest of the command line does not give enough information to guess the family, ip falls back to the default one, usually inet or any. link is a special family identifier meaning that no networking protocol is involved.
	`-4`		shortcut for `-family inet`
	`-6`		shortcut for `-family inet6`
	`-B`		shortcut for `-family bridge`
	`-M`		shortcut for `-family mpls`
	`-0`		shortcut for `-family link`
`-o`	`-oneline`		output each record on a single line, replacing line feeds with the '\' character. This is convenient when you want to count records with wc(1) or to grep(1) the output.
`-r`	`-resolve`		use the system's name resolver to print DNS names instead of host addresses.
`-n`	`-netns`	`<NETNS>`	switches ip to the specified network namespace `NETNS`.
`-N`	`-Numeric`		Print the number of protocol, scope, dsfield, etc directly instead of converting it to human readable name.
`-a`	`-all`		executes specified command over all objects, it depends if command supports this option.
`-c`	`-color`	`[={always\|auto\|never}]`	Configure color output. If parameter is omitted or `always`, color output is enabled regardless of stdout state. If parameter is `auto`, stdout is checked to be a terminal before enabling color output. If parameter is `never`, color output is disabled. This flag is ignored if `-json is also given`.
`-t`	`-timestamp`		display current time when using monitor option.
`-ts`	`-tshort`		Like -timestamp, but use shorter format.
`-rc`	`-rcvbuf`	`<SIZE>`	Set the netlink socket receive buffer size, defaults to 1MB.
	`-iec`		print human readable rates in IEC units (e.g. 1Ki = 1024).
`-br`	`-brief`		Print only basic information in a tabular format for better readability. This option is currently only supported by `ip addr` show and `ip link` show commands.
`-j`	`-json`		Output results in JSON.
`-p`	`-pretty`		The default JSON format is compact and more efficient to parse but hard for most users to read. This flag adds indentation for readability.

-n, -netns

-n <NETNS> simplifies

ip netns exec NETNS ip [ OPTIONS ] OBJECT { COMMAND | help }

to

ip -n[etns] NETNS [ OPTIONS ] OBJECT { COMMAND | help }

COMMAND

COMMAND specifies the action to perform on the object.

The set of possible actions depends on the object type.

As a rule, it is possible to add, delete and show/list objects, but some objects do not allow all of these operations or have some additional commands.

The help command is available for all objects. It prints out a list of available commands and argument syntax conventions.

If no command is given, some default command is assumed. Usually it is list or, if the objects of this class cannot be listed, help.

Examples

Shows addresses assigned to all network interfaces.

ip addr

Show the current neighbour table in kernel:

ip neigh

Bring up interface x:

ip link set x up

Bring down interface x:

ip link set x down

Show table routes:

ip route

TODO

Show result in brief/tabular format:

$ ip -br -c a
