#!/bin/bash
WTIME="60"
#here I defined the logfile's location
logfile=/home/user/pppd/con.log
#the heart of this script lies right here
#just ping google.com with one packet, pipe it's stderr to egrep and match either of those words
#egrep's -c tells to output the number of matches
status=$(ping -c 1 google.com 2>&1 | egrep -c "\<unknown\>|\<unreachable\>")
if [ $status -eq 0 ]; then
#the -n says stay in this line after outputting
#print an empty line
echo "" >> $logfile
echo -n "Already Connected - " >> $logfile
#output date to the logfile
date >> $logfile
#exit with success code
exit 0
fi
if [ ! $status -eq 0 ]; then
echo "" >>$logfile
echo -n "Not Connected - " >> $logfile
date >> $logfile
