I don't understand the parameters in a statement that uses the sh library

[RedSkeleton007]

I'm putting together a hacking program for a school project. I found the following ping sweep script on youtube:

#PingSweep.py
#This program will find all of the active ip addresses in a network
import ipaddress
import sh

print("Enter a network address with a slash number.")
chooseNetworkAddress = input("")
network = ipaddress.ip_network(unicode(chooseNetworkAddress))

for i in network.hosts():
    try:
        sh.ping(i, "-c l")
        print(i, " is active")
    except sh.ErrorReturncode_l:
        print(" no response from", i)

But I don't understand the "-c l" parameters used on line 12. Does anybody know what those are supposed to do?

It is probably ping -c 1. This causes ping to stop after 1 request, according to the ping command's manual.
