Hello guys,

This truly is a newbie question. I'm trying to make a loop to execute simultaneous commands indefinitely while using variable. Here is how my mess looks like (this is just an example):

#!/bin/bash
IP=`shuf -n 1 IP.txt`  # I figured this would be easier to select random lines from a file
TIMES=`shuf -n 1 TIMES.txt`

while :
do
ping -c $TIMES $IP &  # "&" to execute commands simulatenously, right?
ping -c $TIMES $IP &
ping -c $TIMES $IP &
	sleep 1
done

Where is your script "reading" the new IP for the while loop ? (I see not...)

I would have expected:

...
..
while read IP
do
   .
   .
#or 
while IP=`command...`
do
   .
   .

In the stupid mind of mine, I thought that using $IP should execute `shuf -n 1 IP.txt` each time $IP is used...

So youve got the logic right now ?

Yes, the logic, thanks vbe. I've got some reading to do now

ping -c `shuf -n 1 TIMES.txt` `shuf -n 1 IP.txt`  does the trick !
