如果我运行这个命令，我得到端口：

sudo lsof -t -i:9001

所以…现在我想运行：

sudo kill 'sudo lsof -t -i:9001'

我得到这个错误消息：

ERROR: garbage process ID "lsof -t -i:9001".
Usage:
  kill pid ...              Send SIGTERM to every process listed.
  kill signal pid ...       Send a signal to every process listed.
  kill -s signal pid ...    Send a signal to every process listed.
  kill -l                   List all signal names.
  kill -L                   List all signal names in a nice table.
  kill -l signal            Convert between signal numbers and names.

我尝试sudo kill’lsof -t -i：9001’以及
