Hello, I am writing a script that is going to ping a remote host but I want the user to be able to enter in the interval and size when he runs the program. For example the user would enter this to initialize the script.
The code that I have running so far is:
#!/bin/bash
host=db.macom.com
ping $host $1 $2 $3 $4
ok so now for example my output is:
64 bytes from host: icmp_seq=0 ttl=64 time=2.22 ms
64 bytes from host: icmp_seq=1 ttl=64 time=0.537ms
64 bytes from host: icmp_seq=2 ttl=64 time=0.575 ms
64 bytes from host: icmp_seq=3 ttl=64 time=0.585 ms
64 bytes from host: icmp_seq=4 ttl=64 time=0.578 ms
And then once the ping either times out or the user presses cntrl C you get
5 packets transmitted, 5 received, 0% packet loss, time 12009ms
etc...
My question is how do I reference that number of packets transmitted and received so that I can calculate if they are equal or not. I know i would put those values into variables but what do I set each variable equal too?
