ip


SYNOPSIS

       ip [ OPTIONS ] OBJECT { COMMAND | help }

       ip [ -force ] -batch filename

       OBJECT := { link | address | addrlabel | route | rule | neigh | ntable
               | tunnel | tuntap | maddress | mroute | mrule | monitor | xfrm
               | netns | l2tp | tcp_metrics | token }

       OPTIONS := { -V[ersion] | -h[uman-readable] | -s[tatistics] |
               -d[etails] | -r[esolve] | -iec | -f[amily] { inet | inet6 | ipx
               | dnet | link } | -4 | -6 | -I | -D | -B | -0 | -l[oops] { max-
               imum-addr-flush-attempts } | -o[neline] | -rc[vbuf] [size] |
               -t[imestamp] | -ts[hort] | -n[etns] name | -a[ll] }


OPTIONS

       -V, -Version
              Print the version of the ip utility and exit.

       -h, -human, -human-readable
              output statistics with human readable values followed by suffix.

       -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
              Output 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)

       -6     shortcut for -family inet6.

       -B     shortcut for -family bridge.

       -D     shortcut for -family decnet.

       -I     shortcut for -family ipx.

       -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.  Actually
              it just simplifies executing of:

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

              to

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

       -a, -all
              executes specified command over all objects, it depends if com-
              mand supports this option.

       -t, -timestamp
              display current time when using monitor option.

       -ts, -tshort
              Like -timestamp, but use shorter format.

              - 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.

       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.

       delete and show (or 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 com-
       mands 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.
