[SOLVED] Use GREP on array to find words

Issue

Given the following array in Shell Programming

foo=(spi spid spider spiderman bar lospia)

I would like to use GREP to search for all words in the array which has the 3 letters spi

Correct output : spi spi spider spiderman lospia

I have tried something like this

foo=(spi spid spider spiderman)

grep "spi" foo

But it seems it is wrong , what is the correct way to go about it ???

Solution

The following will print out all words that contain spi:

foo=(spi spid spider spiderman bar)
for i in ${foo[*]}
do
    echo $i | grep "spi"
done
