Question 1. In bash, if I type "ls > logfile", what program opens logfile, bash or ls? Why?

Question 2. If you wanted to change a user's uid, what is one file that you would definitely have to change? Why?

Question 3. When a process creates a file, the file's owner is set to the filesystem uid of the creating process. The filesystem uid is normally set to be equal to the process's effective uid. If you make a program setuid root, will that change the default ownership of the files it creates? Explain.
