[why] iozone-bs.yaml has combined multiple parameter to single, so, iozone tool also need change the way of parsing parameter. [how] change the way of parsing parameter.

small example for parsing parameter:

test=" write, read, rand_rw" OLD_IFS="$IFS" IFS="," array=($test) IFS="$OLD_IFS"

for ele in ${array[@]} do case $ele in "write") echo $ele ;; "read") echo $ele ;; "rand_rw") echo $ele ;; esac done

output: ~/workspace/shell_learning% ./test.sh write read rand_rw

if use "${array[@]}" in for loop, there will be no output.
