Problems in generating the mail from cron -- very urgent help me
Hi,
I wrote a script which generates a mail automatically under certain condition. When i execute the script manually in unix the script is getting executed and the condition works accordingly and the mail is also generated. But when it is pu into cron the mail is not generated and the condition also seems to be going wrong. The return code of the mail command is '1'. Please help me out.
Below is my sample format of my script,
#!/bin/sh
echo "The Job Successfully scheduled at : `date` "
cd **to some path**
ls **some condition** > filetmp.dat
while read line
do
grep $line file.dat > a1.dat
res=`echo $?`
echo "$res"
if [ $res = "1" ]
then
len=`echo $line | wc -c`
echo $len
if [ $len = "30" ]
then
subfile=`echo $line | cut -c1-18`
echo $subfile
cd **to some path**
grep TFS $subfile > a2.dat
tfs=`echo $?`
if [ $tfs = "0" ]
then
echo "FOUND"
else
echo "NOT FOUND"
while read address
do
echo "
Hi ,
This is an alert " | Mail -s "Test Mail" $address
echo "$? --> Mail Status for $address"
done < "addr.dat"
fi
elif [ $len = "44" ]
then
subfile=`echo $line | cut -c1-18`
echo $subfile
cd **to some path**
grep TFS $subfile > a2.dat
tfs=`echo $?`
if [ $tfs = "0" ]
then
echo "FOUND"
else
echo "NOT FOUND"
while read address
do
echo "
Hi ,
This is an alert " | Mail -s "Test Mail: " $address
echo "$? --> Mail Status for $address"
done < "addr.dat"
fi
else
subfile1=`echo $line | cut -c1-35`
echo $subfile1
cd **to some path**
grep TFS $subfile1 > a2.dat
tfs=`echo $?`
if [ $tfs = "0" ]
then
echo "FOUND"
else
echo "NOT FOUND"
while read address
do
echo "
Hi ,
This is an alert" | Mail -s "Test Mail:" $address
echo "$? --> Mail Status for $address"
done < "addr.dat"
fi
fi
fi
done < "filetemp.dat"
mv filetmp.dat file.dat
echo "The Job Successfully ended at : `date` "

calendar
CALENDAR(1) General Commands Manual CALENDAR(1)
NAME
calendar - reminder service
SYNOPSIS
calendar [-] [-r]
OPTIONS
- Work for every user and send mail to him
-r Restrict multiple execution on the same day
EXAMPLES
calendar # Check calendar file in current directory
calendar # Normary used under the control of cron(8)
calendar -r # Normary used in /etc/rc file
DESCRIPTION
Basically calendar program consults the file calendar in the current directory and display lines which contain today's or tomorrow's date.
Month-day formats such as '12/25', 'Dec. 25', 'december 25', '*/25', '12/*', '*/*' are recognized. The asterisk means 'all' days or 'all'
months. On weekends 'tomorrow' extends through next Monday without any consideration about holidays. To prevent ambiguity, the formats
'25 Dec.' and '25/12' are not recognized.
When an argument - is present, calendar works for all users with a file calendar in their login directories and sends them mail. Normally
this is done daily under the control of cron.
The -r option does its the same job as - option, but touches the calendar to prevents further access on the same day. Normally this is
done in the /etc/rc file on a machine which may be booted several times in one day.
