Oh, is he trying to get the first non-null component of a /-delimited
pathname? I can never tell any more....
IFS=/ read -a tmp <<< '/home/'; echo "${tmp[1]}"
Using regular expressions to split a string into fields is so unnatural
to me. ${tmp[1]} is the second element of the array. If you need to
search through it for the first non-null element, you can write a loop
for that.
