ping-t script

[mo jaber]

I need a script that recievs an IP adress and a number of seconds (X secodns). and every X seconds reports if the IP replies.

[Fred Ruffet]

#!/bin/sh

IP=$1
SECS=$2
while true
do
ping -c 1 $IP
sleep $SECS
done

You can add controls, but it might work...

[mo jaber]

thanks for this answer.
but can you write it without using "do" or "while".

[Fred Ruffet]

I made a mistake :
it is ping $IP -n 1 (-c 1 must be on other system)

If you want it without while and do, just do :
alias bloup=while
aliad foo=do
bloup true
foo
ping $IP -n 1
sleep $SECS
done

here it is :)

Mo -
As Fred suggests, you will wnat this to run in some window of time and most likely not into infinity.
Thus you will want a conditional statement of some sort to limit this window.
i.e.
limit=`date +%H`
while [ $limit -lt 17 ]
do
ping 10.0.0.45 -n 5 > /tmp/ping_file
limit=`date +%H`
done
