Problem
1. You have to toggle repeatedly between /usr/include and /usr/lib. What shortcut will you use?
2. How do you copy all files from henry's home directory even if you don't know its absolute pathname?
3. Why does every UNIX system have /etc/profile? When is this file executed?
4. If you have the files .bash_profile and .profile in your home directory, will Bash read them both on login?
5. A shell script also runs the login file. True or false?
