Yeah? No looking it up, give me a bash script for a ping scan of a subnet with a 24 bit mask.
-
#!/bin/bash
ping 255.255.255.0 > checker &
sleep 5
kill "$!"
grep unreachable checker || echo '255.255.255.0'
ping 255.255.255.1 > checker &
sleep 5
kill "$!"
grep unreachable checker || echo '255.255.255.1'
ping 255.255.255.2 > checker &
sleep 5
kill "$!"
grep unreachable checker || echo '255.255.255.2'
...
Did I do it coach? 😭

nmap -sn x.x.0.0/24 I think, was a while. Pure coincidence how I know.
Edit: no, it's one less x because 16 is the middle.

Close!

That's not a bash script silly.

Just add
#!/bin/bashbefore the code from above. -
Dang.

-
#!/bin/bash
for i in 0..254; do ping -c 4 10.0.0.$i &; done
wait
Throwing that many background tasks at once is a little risky, but awesome
