ESXi esxcli 错误：未知命令或命名空间 vm 进程 kill –t=soft –w=67909

我正在运行 ESXi 6.5 嵌入式主机客户端。当我 ssh 进入系统时，我可以运行esxcli vm process list并获得预期的输出：

testserver1
   World ID: 67909
   Process ID: 0
   VMX Cartel ID: 67908
   UUID: someuuid
   Display Name: testserver1
   Config File: /vmfs/volumes/somelocation/testserver1/testserver1.vmx

但是如果我运行esxcli vm process kill –t=soft –w=67909我会得到错误Error: Unknown command or namespace vm process kill –t=soft –w=67909

为了确认我正在运行正确的命令，我运行esxcli vm process kill -help并得到

Error: Invalid option -h

Usage: esxcli vm process kill [cmd options]

Description: 
  kill                  Used to forcibly kill Virtual Machines that are stuck and not responding to normal stop operations.

Cmd options:
  -t|--type=<str>       The type of kill operation to attempt. There are three types of VM kills that can be attempted:   [soft, hard, force]. Users should always
                        attempt 'soft' kills first, which will give the VMX process a chance to shutdown cleanly (like kill or kill -SIGTERM). If that does not work
                        move to 'hard' kills which will shutdown the process immediately (like kill -9 or kill -SIGKILL). 'force' should be used as a last resort
                        attempt to kill the VM. If all three fail then a reboot is required. (required)
  -w|--world-id=<long>  The World ID of the Virtual Machine to kill. This can be obtained from the 'vm process list' command (required)

你能看到我做错了什么可能会阻止这个命令工作吗？我意识到文档中vim-cmd有替代方案，但我试图弄清楚为什么文档中的第一个选项会响应，就像它甚至不是有效的命令一样。
