# tink target create --help
create a target

Usage:
  tink target create [flags]

Examples:
tinkerbell target create '{"targets": {"machine1": {"mac_addr": "02:42:db:98:4b:1e"},"machine2": {"ipv4_addr": "192.168.1.5"}}}'

Flags:
  -h, --help   help for create

It should be:

tink target create '{"targets": {"machine1": {"mac_addr": "02:42:db:98:4b:1e"},"machine2": {"ipv4_addr": "192.168.1.5"}}}'

not:

tinkerbell target create '{"targets": {"machine1": {"mac_addr": "02:42:db:98:4b:1e"},"machine2": {"ipv4_addr": "192.168.1.5"}}}'
