CPU & Memory Hash Table like implementation in unix
Hi all,

I just downloaded this example from the net. I was looking around for a hash table like implementation in unix when I came across this.

Code:
ARRAY=( "cow:moo"
        "dinosaur:roar"
        "bird:chirp"
        "bash:rock" )

for animal in ${ARRAY[@]} ; do
    KEY=${animal%%:*}
    VALUE=${animal##*:}
    printf "%s likes to %s.\n" $KEY $VALUE
done

Can anyone please help me how does the ${animal%%:*} match to cow , is it a regular expression ?

Thanks in advance ...
