Takes a text file of IPs/hostnames to ping as an argument, and runs ping against all of them. Alternatively, uses cURL in the case of URLs. Runs timers for anything that is 'down'.

1. Clone this repo: git clone https://github.com/Starttoaster/pinger.git && cd pinger/

2. Make a text file to run the tests on. Can be named anything, and store the IPs/hostnames/URLs on new lines.

3. Run the script: ./pinger.sh <filename>

8.8.8.8
1.1.1.1
8.8.4.4
https://google.com
https://example.com
https://cloudflare.com
network-switch1
network-switch2
corerouter01

In order we have a few examples of valid IP addresses, a few valid URLs (for best results please use the full URL including http/https), and some network hosts if configured on your private network. Here is the output after running the script against this example document:

Hostname              : Status    : Method    : Timer
8.8.8.8               : ONLINE    : ping      :
1.1.1.1               : ONLINE    : ping      :
8.8.4.4               : ONLINE    : ping      :
https://google.com    : ONLINE    : cURL      :
https://example.com   : ONLINE    : cURL      :
https://cloudflare.com: ONLINE    : cURL      :
network-switch1       : OFFLINE   : ping      : 00:00:16
network-switch2       : OFFLINE   : ping      : 00:00:16
corerouter01          : OFFLINE   : ping      : 00:00:16

Obviously, the internal hostnames show as "OFFLINE" because they don't exist in my local network. But if I had something named "corerouter01" specified in my /etc/hosts file then it would return ping.
