please any one can suggest me how to use bitesie || opearator to do this
#initallize a=0 b=0
#condition
if [ $? -ne 0 ]then
a=0
else a=1
fi
#bitwise or opeartion b = a || b

Bitwise or operation-
Bit_or () {
a=0
b=0
if [[ `expr "$a" + "$b"` > 0 ]]
then
echo "1";
else
echo "0";
fi
}
Bitwise and operation-
Bit_and () {
a=1
b=1
if [[ `expr "$a" \* "$b"` > 0 ]]
then
echo "1";
else
echo "0";
fi
}
||
is a logical-OR, not a bitwise-OR (in both sh and C).

Plain sh does not have bitwise operators.
BASH does, though.
$ echo $((1|2|4|8|16|32|64|128))
255
$ echo $((0^0))
0
$ echo $((0^1))
1
$ echo $((1^0))
1
$ echo $((1^1))
0
$ echo ((1<<4))
16
$ echo $((255 & 7))
7

etc.
