#include "ip_common.h" /* #include "libbb.h" is inside */

/* iproute2-5.17.0:
-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 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 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 }
-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. If specified multiple times, the last
one takes precedence. This flag is ignored if -json is also given.
Used color palette can be influenced by COLORFGBG environment variable.
-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 , ip link show
& ip neigh show commands.
-j, -json
Output results in JavaScript Object Notation (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.
