Shell Programming and Scripting

Hi,

I have written the following UNIX for HP-UX 11i. The script basically checks for files older then 45mins in 2 repective directories and then sends and email to the administrator about them.

Problem with the script is that I can run it from the command line and crontabtab but 80% of the time it errors out with the following error message "date: bad conversion".

I'm puzzled as to why it works brilliantly sometimes and why majority of the times it errors out with the above error message. Can a UNIX scripting guru please advise. Script displayed below:

#!/usr/bin/ksh
mailgroup='testuser@xxx.com'

LOGFILEIN=/tmp/sipstimein.log
LOGFILEPROC='/tmp/sipstimeproc.log'

#GET AND PARSE THE CURRENT DATE
date "+%m %d %H %M" | while read MONTH DAY HOURS MINS
do

#SUBTRACT 45 MIN
MINS=$(($MINS-45))

if [ $MINS -lt 0 ]
then
HOURS=$(($HOURS-1))
MINS=$(($MINS+60))
fi

#TOUCH A FILE SO THAT IT IS 45 MINUTES OLD
touch -t ${MONTH}${DAY}${HOURS}${MINS} /tmp/oldtime
done

#Find files older then 45mins condition
find /interface/data8/sips/proc ! -newer /tmp/oldtime | while read FILENAME
do
#CHECK THAT IT IS A REGULAR FILE, AND NOT A DIR OR
# CHARACTER FILE, BEFORE RUNNING THE COMMAND AGAINST IT
if [ -f $FILENAME ]
then
echo "$FILENAME" >$LOGFILEIN
sleep 4
mailx -s "Files have been detected older then 45mins in PROD system for SIPS in the PROC directory" <$LOGFILEIN $mailgroup
2>&1
fi
done

find /interface/data8/sips/in ! -newer /tmp/oldtime | while read FILENAME
do
#CHECK THAT IT IS A REGULAR FILE, AND NOT A DIR OR
# CHARACTER FILE, BEFORE RUNNING THE COMMAND AGAINST IT
if [ -f $FILENAME ]
then
echo "$FILENAME" >$LOGFILEPROC
sleep 4
mailx -s "Files have been detected older then 45mins in PROD system for SIPS in the IN directory" <$LOGFILEPROC $mailgroup
2>&1
fi
done

#rm /tmp/oldtime

THANKS and help appreciated.

I think your problem is with your $HOURS and MINS calculations. If you subtract 45 from 50, for example, you get "5" not "05". So your touch command gets confused because the timestamp is not formatted "MMDDhhmm".

Since you are using ksh, you could fix using...

Code:

typeset -Z2 HOURS MINS

However, if you have perl, perhaps try...

Code:

:
#GET AND PARSE THE CURRENT DATE. SUBTRACT 45 MIN (2700 SECONDS)
STAMP=$(perl -e '($ss, $mm, $hh, $DD, $MM, $YY) = localtime(time() - 2700);
printf "%04d%02d%02d%02d%02d", $YY + 1900, $MM + 1, $DD, $hh, $mm')

#TOUCH A FILE SO THAT IT IS 45 MINUTES OLD
touch -t $STAMP /tmp/oldtime

Thanks Ygor, problem fixed.
