Question Write a script to send alert for some particular hours in a day

Hi All,
I have a have a script which checks for some processes whether they are running or not and if they are not running then it send a mail specifying that the processes are not running.
This particular script example abc.ksh is runs in a cron like this
Code:
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/usha/abc.ksh

Now my problem is everyday for total four hours say morning 6 to 8 and evening 6 to 8 these processes will not run and there is a scheduled downtime.And i have been told that cron entry should not be changed.
So, is there any way to add any condition in my script itself to the part where i am sending a mail to check for the time and if it is between morning 6 to 8 and evening 6 to 8 then it will not send a mail.Else if it is any other time of the day then it will send a mail..
Thanks to all in advance.

Hi,

Just include condition inside your script..before checking the process status..

check current timestamp which should not be 6-8 AM
if that condition is true..
then check for current timestamp which also should not be 6-8 PM
if both the condition is true then go ahead and check for process..
if anyone of the condition is true then give exit..withou checking process..

Thanks

its better to share yur codes...rather than giving different solutions..

Code:
if [ condition ]
true
exit 1;
if [ condition ]
true
exit 1;
  fi
    fi

Thanks

Thanks, for your reply.But i am aware of if condition syntax but my problem how to test that the time is between morning 6to 8 and evening 6 to 8 and the not to send mail alert during that time.I have a problem incorporating this in my script.
do i need to assign some variable with the date command but then how to check cor two hours as my script has to run 24 hours.but inside my script the mail alert will not be sent for some amount of time.but it sends alerts for the rest of the time.

Thanks

Code:
#!/bin/ksh
echo "Print Current Time"
v=`date +%H`
echo $v
                if [[ $v -ge 6 ]] && [[ $v -le 8 ]]; then
                        echo "please get exit"
                        exit 1;
                                else
                if [[ $v -ge 18 ]] && [[ $v -le 20 ]];then
                        echo "Please get exit"
                        exit 1;
                                else
                        echo "check for process"
                        echo "mail part"
                  fi
                fi

Thanks
