Apologies for the confusion...
My requirements are still the same.
1. Script should run only on sunday.
2. If my internal code runs to success in 3 attempts. Counter should reset to 1 and exit.
3. If the interal code failed on the 3rd attempt. It should send an email and exit. Here again the counter should be reset to 1.

---------- Post updated at 09:14 AM ---------- Previous update was at 09:11 AM ----------

Will post the code in some time as I am away from my laptop. .

With the modified code I gave those requirements are met.

You have a bonus too...

The value n=3 was deliberately chosen to execute the final "if" statement AND also give you an email to flag if someone was trying to run it on any other day than Sunday as well as resetting the value back to n=1 ...

Of course you can still exit 1 there if you so desire and not have these extra emails that is why it is just commented out...

Hi bakunin,

I had an error msg.

error msg:
Code:
grep: RE error 41: No remembered search string.

My mistake i have not mentioned absolute path of attempts.log

Please help me understand how the values of fLog are.

As per my understanding, fLog and attempts.log should be given with absolute path.
I have deployed my scripts in the below path

Code:
path: /usr/local/wam/scripts

Kindly suggest, Below is the code

Code:
PCheckDOW ()
{
typeset chDOW="${1:0:3}"
if [ "${chDOW}" != "Sun" ] ; then
     return 1
fi
return 0
}
pCheckAttempts ()

{
typeset fLog="${1}"
typeset iCurrDay="${2}"
typeset iNrOfAttempts=0
typeset iMaxAttempts=3
grep "$iCurrDay" "$fLog" > "${fLog}.tmp" 
mv "${fLog}.tmp" "${fLog}"
echo "$iCurrDay" >> "$fLog"
iNrOfAttempts=$(grep -c "$iCurrDay" "$fLog")
if [ "$iNrOfAttempts" -gt "$iMaxAttempts" ]
then
     echo "Attempts $iNrOfAttempts exceeded maximum of attempts $iMaxAttempts, Sending mail"

return 1
fi
return 0
}

I have no idea where that comes from.

It does not matter where your script is. Change the one line:

Code:
typeset fAttemptsLog="/tmp/attempts.log"

To put the attempts.log file somewhere else and/or name it differently. "fLog" will hold what is given to the function as the first argument. As long as it points to a valid file everything is fine.

I hope this helps.

Thanks bakunin, Sorry for my delayed response as i need to test it only on sundays.
So as i need attempts.log in
Code:
/usr/local/wam/scripts

I am modifying as below, suggest me if i am wrong.

Code:
typeset fAttemptsLog="/usr/local/wam/scripts/attempts.log"

------------


I Also realized a mistake that i did with out path....

Code:
typeset fAttemptsLog="attempts.log"

.

Exactly. In general, whenever you mention a file in a script you should ALWAYS do it with a full path. This way the script will work regardless of where it is run from.

This is exactly what you should avoid. This will place the log file whereever the script happens to be called at (this palce could differ from one run to the next) and is a first-rate device to clutter up your filesystems with an abundance of abandoned "attempts.log"-files.

I hope this helps.
