For loop iterating over a list of IP addresses from a txt file
It's me again. I have the script working, but the script is not pinging the address 3 times and moving on to the next address. Also, the message that I want to display before each new ping session is not printing.
As always, any help is great.
Here's the cute little codelette I have so far...
Code:
#!/bin/bash
# Script to test server connectivity using ping
for addr in $(cat vms.txt)
do
echo "Pinging IP address "$addr
ping -c 3 "$addr"
done

Perfect. Thank you. It appears, since I was experimenting with Geany (I use VIM all the time), I hadn't saved the script so the changes were not registering. Thank you for everything! I am the crowned prince of making things harder than they need to be.

perhaps slowing down a bit and double checking your work might help.
No harm no foul.
Cheers!
