I was experimenting, and found this works:
sudo xterm -e "echo 1 > hello"
It created a file owned by root. But I found I was able to remove it
without being root even though group and world permissions were read
only.
thats because sudo exceutes a xterm as root
then this xterm executes a shell (as root) and this root shell does
the redirection.
Yes, but why did it allow me to delete the file? I was not root
then. Try it.
