month= date +"%m"
if [ "$month" -eq 3 ] || [ "$month" -eq 6 ] || [ "$month" -eq 9 ] ||
[ "$month" -eq 12 ] ; then
inc_flg = 1
else
inc_flg = 2
fi

But i am getting inc_flg =2 always.please help me to solve this issue.Is there anyother way to write a script???please help me.thanks in advance

u can directly subtituite command in loop u can do this it works

#!/bin/sh

if [ `date +"%m"` -eq 3 ] | [ `date +"%m"` -eq 6 ] | [ `date +"%m"` -eq 9 ] | [ `date +"%m"` -eq 12 ] ; then
echo "inc_flg = 1"
else
echo "inc_flg = 2"
fi

You are missing the backticks.

"neater" way to write your if else statement

3,6,9,12 all have a remainder of zero when divided by 3. The other months will have a non-zero remainder. You can use month%3 as the test. If you must have variable called inc_flg with the above mentioned properties, you could just do:
((inc_flg=2-!(month%3)))

u have made my day gud gentlemen..i have used reborg's stuff.....But thanks for all.........
