Hi it means the if condition is not working correctly

can you try this

Code:
if [[ ( "$date" -eq "$DAT" ) && ( "$day" = "$DAY" ) && ( "$month" = "$MON" ) ]

Code:
if [ ("$date" -eq "$DAT") && ("$day" = "$DAY") && ("$month" = "$MON") ]

Message: ./new.sh[15]: syntax error at line 18 : `(' unexpected

Code:
if [ "$date" -eq "$DAT" && "$day" = "$DAY" && "$month" = "$MON" ]

It gives all the names as before

'IF' is not getting executed properly Smilie donno Y!

Looking at your execution log
Code:
+ [ 05 -eq 05 -a day = Thu -a month = Dec ]
+ [ 05 -eq 05 -a day = Thu -a month = Dec ]
+ [ 06 -eq 05 -a day = Thu -a month = Dec ]

it's surprising that anything is printed because every test is FALSE.
However, if I execute (in bash!)
Code:
while IFS=',' read name date day month year
  do  if [ "$date" -eq "$DAT" -a "$day" = "$DAY" -a "$month" = "$MON" ]
        then echo $name
      fi
  done < file
sreenadh

, you can see that the result is what you want. Are you sure you're sharing your code as is? Try the -v option.

Code:
#!/bin/ksh
#Initial Variables
IFILE="$HOME/bday.csv"
OFILE="bday_out"$$
MAILID="abc@xxx.com"
#get today's date & month
DAT=`(date '+%d')`
DAY=`(date '+%a')`
MON=`(date '+%b')`
while IFS=',' read name date day month year
do
set -x
if [ "$date" -eq "$DAT" -a "$day" = "$DAY" -a "$month" = "$MON" ]
set +x
   then echo $name
   fi
done < $IFILE > $OFILE
set -x
if [ -f $OFILE -a -s $OFILE ]
set +x
then
   sed -i '1i The following users celebrate their birthday:\n' $OFILE
   mailx -s "Birthday on: $DAT" $MAILID  < $OFILE
  # \rm $OFILE
   echo "Birthday mail sent"
else
   echo "No birthdays today"
fi

This is the code i am executing & i am trying this in my office, dont have bash here! Smilie

Tried this IF condition buddy, but still the result is same Smilie
Is it because i am executing it in Ksh ? i cant do it in bash though!

Strange enough. Well, last resort: Run the entire script with set -vx and attach the entire execution log here.
# 14  
Old 12-05-2013
Please find the log here

Code:
+ [[ 05 -eq 05 ]]
+ [[ Thu = Thu ]]
+ [[ Dec = Dec ]]
+ [[ 05 -eq 05 ]]
+ [[ Thu = Thu ]]
+ [[ December = Dec ]]
+ [[ 06 -eq 05 ]]
if [ -f $OFILE -a -s $OFILE ]
set +vx
then
   sed -i '1i The following users celebrate their birthday:\n' $OFILE
   mailx -s "Birthday on: $DAT" $MAILID  < $OFILE
  # \rm $OFILE
   echo "Birthday mail sent"
else
   echo "No birthdays today"
fi
+ [ -f bday_out1560592 -a -s bday_out1560592 ]
