NAME
       devlink - Devlink tool

SYNOPSIS
       devlink [ OPTIONS ] { dev|port|monitor|sb|resource|region|health|trap }
               { COMMAND |  help }


       devlink [ -force ]  -batch filename



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


       -b, -batch <FILENAME>
              Read commands from provided file or standard input and invoke
              them.  First failure will cause 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
              When combined with -j generate a pretty JSON output.


       -v, --verbose
              Turn on verbose output.


       -s, --statistics
              Output statistics.


       -N, -Netns <NETNSNAME>
              Switches to the specified network namespace.


       -i, --iec
              Print human readable rates in IEC units (e.g. 1Ki = 1024).


       -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.
