How to run a snort rule over pcap file

I'm having a pcap file, and what i wanted to know is how can i apply the Snortrule below which i've already written within the rules folder in ma log folder:

alert icmp any any -> any any (msg:"TCP Packet"; sid:477; rev:3;)

How can i execute this rule over the pcap file i have? This is just a sample rule but what exactly i want to know is to filter the packets within the pcap file using the snort rule?

Any help would be appreciated.
