k-shell anyone?
Need some help on this script.. I've managed to get a fibianci script working but I want to find the sum sum of all the even-value terms which don't exceed 4 million
#!/bin/sh
# Shell scrpt to generate Fibonacci series using recursion
export MINIDX=2
fibonnacci()
{
case $n in
0) echo 0; return;;
1) echo 0 1; return;;
*) echo -n 0 1
a=0; b=1; c=2;
while [ $c -le $n ]
do
t=$(( a + b ))
echo -n " $t"
a=$b; b=$t;
c=$(( c + 1 ))
done
echo
return;;
esac
}
#
n=${1:-10}
if [ ! `expr $n + 1 2> /dev/null` ] ; then
echo "Value of the arguments < $n > IS NOT an integer!"
exit 1
fi
echo "Fibonnacci series for value $n is:"
while
fibonnacci $n
exit 0
thinking of something like,
while n < 4000000
sum +t
#!/bin/sh
# Shell scrpt to generate Fibonacci series using recursion
export MINIDX=2
fibonnacci()
{
case $n in
0) echo 0; return;;
1) echo 0 1; return;;

a=0; b=1; c=2;
while [ $c -le $n ]

fi

exit 0
