result=`expr $first + $second`
first=$second
second=$result
i=$result

Something's wrong in the syntax of the if/then/else statements.

I tried to fix it but still couldnt find it :wall: .. Can u help me please??!!

Its assignment given by teacher

Thanks

Lets just say that every if needs a fi , and every do needs a done .

We will help you, but we won't do your work for you.

echo "enter a number "
read n
z=0
a=0
fib=0
b=1
echo " fibancci series is "
while [ $z -le $n ]
do
fib=`expr $a + $b`
a=$b
b=$fib
x="true"
m=$fib
for((y=$m-1;y>=2;y--))
do
if [ `expr $m % $y` -eq 0 ]
then
x="false"
break
else
x="true"
fi
done
if [ $x ="true" ]
then
echo "$m"
fi
z=`expr $z + 1`
done

Hi,

did nu check my syntax?! i mean the new one?!!

Run the script in debug mode by placing

set -x

after the shebang line.

What do you want? to print the fib. series? What are the conditions you are trying to avoid?

I want the prime numbers from the fib.series number which the user enter as input!!

I want to print the prime numbers of the fib. number which the user put as input. For example the user enter 5 then the output will be the prime number of fib. series of number 5..

The submisstion of this assignment is tomorow and i couldnt get the right output so far

Try to figure out why this is wrong:

if [ $x ="true" ]

how is it wrong?!!
Oh god i am really going mad out of this script..

My mind jammed :wall:

Remember these statements in a shell need you to put spaces everywhere.

if [ $x = "true" ]
