How to reverse a list of words in a shell string?

I have a list of words in a string:

str="SaaaaE SeeeeE SbbbbE SffffE SccccE"


I want to reverse it in order to get

"SccccE SffffE SbbbbE SeeeeE SaaaaE"


How I can do that with
ash
?

Answer

You can use awk as follows:

echo $str | awk '{ for (i=NF; i>1; i--) printf("%s ",$i); print $1; }'
