Shell script

I don't understand exactly what you are trying to do. I assuming you are 
using the grep 64 to simply extract the pings and not the other crap, 
such as the header and result. I don't understand why you expect the 
number 5?
if I use the command:x=` ping -c 5 entil-zha | grep 64`
Where the single quotes are the grave accent which causes the 
command to be executed, not the single quotes, I would expect x to 
contain:
64 bytes from 192.168.3.23: icmp_seq=0 ttl=255 time=0 ms 64 bytes 
from 192.168.3.23: icmp_seq=1 ttl=255 time=0 ms 64 bytes from 
192.168.3.23: icmp_seq=2 ttl=255 time=0 ms 64 bytes from 
192.168.3.23: icmp_seq=3 ttl=255 time=0 ms 64 bytes from 
192.168.3.23: icmp_seq=4 ttl=255 time=0 ms
