我有一些在tcp / 8051上侦听的REST服务
我在同一主机的无限循环中用curl查询这个服务：
while true; do curl --header "Authorization: Bearer NDkwMjM3NzEtN2U2NS00ZDVkLThhYzItOThmZTliODljNWJj" -k "https://xx7.131:8051/status/service"; done
在其他窗口中，我正在检查与netstat （在根目录下）的连接：
while true; do netstat -antep |grep :8051 && echo ""; done
netstat输出

为什么我看不到PID？
