How to solve: netstat: command not found

netstat has been deprecated in favor of ss

For example:
$ sudo ss -a | grep nfs
tcp    LISTEN     0      64                   *:nfs                   *:*       
tcp    LISTEN     0      64                  :::nfs                  :::*    

$ ss --help
Usage: ss [ OPTIONS ]
       ss [ OPTIONS ] [ FILTER ]

   -l, --listening display listening sockets
   -o, --options       show timer information
   -e, --extended      show detailed socket information
   -m, --memory        show socket memory usage
