Overview
In the previous chapter on the Korn and C shells we covered how to set variables (PS1 and HISTORY) to customize your environment and create aliases. These and other features can be automatically made available after login by modifying specific initialization files. This chapter will show you how to work with various initialization files to make these changes take effect each time you login. We will explain system-wide and user-specific initialization files and cover variables in more detail. You will work with Korn and C shell customization as well as CDE customization.
