       -b, -batch <FILENAME>

              termination of devlink.

       -force Don't terminate devlink on errors in batch mode.  If there were any errors during execution of the
              commands, the application return code will be non zero.

       -n, --no-nice-names
              Turn off printing  out  nice  names,  for  example  netdevice  ifnames  instead  of  devlink  port
              identification.

       -j, --json
              Generate JSON output.

       -p, --pretty

       -i, --iec

       -x, --hex
              Print dump numbers in hexadecimal format.

   OBJECT
       dev    - devlink device.

       port   - devlink port.

       monitor
              - watch for netlink messages.

       sb     - devlink shared buffer configuration.

       resource
              - devlink device resource configuration.

       region - devlink address region access

       health - devlink reporting and recovery

       trap   - devlink trap configuration

   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 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 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.

EXIT STATUS

       Exit status is 0 if command was successful or a positive integer upon failure.
