Yeah, that works - THANKS! I can see the integer comparing itself againist 11 - very nice. but the script is still ending and not notifying the update (when a server comes back up). The script is supposed to compare from the last time it ran and current time it runs and update files with the results and compare them to see if there are any changes. If there are, it should email the updates. Would you mind taking another look?

Current output when script runs
Code:
 + read NAME IP ROUTER
++ grep -w Winchester2 /admin/scripts/crons/ping_servers.sh.serverlist.downlastrun
+ WASDOWN=
++ grep -w Winchester2 /admin/scripts/crons/ping_servers.sh.serverlist.down
+ ISDOWN=
+ '[' -n '' ']'
+ '[' -n '' ']'
+ '[' -z '' ']'
+ '[' -n '' ']'
+ read NAME IP ROUTER
+ '[' -s /tmp/ping_servers.sh.serverlist.upagain -o -s /tmp/ping_servers.sh.serverlist.wentdown ']'
+ '[' -s /tmp/ping_servers.sh.serverlist.stilldown ']'
++ date +%H
+ '[' 12 -eq 11 ']'
+ echo not time for daily notification of servers that are still down
not time for daily notification of servers that are still down
+ '[' -f /tmp/ping_servers.sh.stilldownsent ']'
root@mpt1a02:/admin/scripts/crons#

Here is the code of the script where it compares:

Code:
# look for differences
# in this section, we are looking for what servers just went down,
#  which ones just came back up, and which ones are still down from before
echo lists of recent downs and returns, and servers that remain down
>/tmp/$SCRIPTNAME.serverlist.wentdown
>/tmp/$SCRIPTNAME.serverlist.stilldown
>/tmp/$SCRIPTNAME.serverlist.upagain
while read NAME IP ROUTER
do
  WASDOWN=`grep -w $NAME  /admin/scripts/crons/$SCRIPTNAME.serverlist.downlastru
n`
  ISDOWN=`grep -w $NAME  /admin/scripts/crons/$SCRIPTNAME.serverlist.down`
  if [ -n "$WASDOWN" -a -n "$ISDOWN" ]; then
    echo "$ISDOWN (still down)" >>/tmp/$SCRIPTNAME.serverlist.stilldown
  fi
  if [ -n "$WASDOWN" -a -z "$ISDOWN" ]; then
    echo "$NAME $IP $ROUTER (up again)" >>/tmp/$SCRIPTNAME.serverlist.upagain
  fi
  if [ -z "$WASDOWN" -a -n "$ISDOWN" ]; then
    echo "$ISDOWN (just went down)" >>/tmp/$SCRIPTNAME.serverlist.wentdown
  fi
done</tmp/$SCRIPTNAME.serverlist
# cat /tmp/$SCRIPTNAME.serverlist.upagain /tmp/$SCRIPTNAME.serverlist.wentdown /
tmp/$SCRIPTNAME.serverlist.stilldown
