    NAME
           ip - show / manipulate routing, devices, policy routing and tunnels
    
    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)
    	      means loop until all addresses are removed.
    
    
           -f, -family <FAMILY>
    	      Specifies the protocol family to use. The protocol family iden‐
    	      tifier can be one of inet, inet6, bridge, ipx, dnet 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.
    
    
           -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.
    
    
           -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).

    	      - multicast address.

    	      - watch for netlink messages.

           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.
    
    
           xfrm   - manage IPSec policies.
    
    
           The names of all objects may be written in full or abbreviated form,
           for exampe address can be abbreviated as addr or just a.
    
    
       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 (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.
