check if contents of an array is empty
hi,

I have this array

Code:
a=("" "" "")

Is there a command that I can use to check if all members of the are empty?
I really don't like to use for or while loop.

thanks!

wait, I got it already

Code:
i=echo ${a[@]} | wc -w
if [ $i -eq 0] ; then
    echo empty
fi

anyway, any other solutions will be appreciated

Another way :
Code:
set -- ${a[*]}
if [ $# -eq 0 ] ; then
    echo empty
fi
