sorry if re post. i just wanna be careful, and also i didn't find any answer that suit with my case.

i have few folder name under /home/user/www
say it: f1, f2, f3, f4, f5
and there are few files under folder f1-f5 as well

i usually use: rm -rf /home/user/www/* to delete them all [f1-f5]

but how to delete all of them except folder f1?

thanks
