As Code Listing 8.14 (on the next page) shows, you look at your ksh configuration files using more or the editor of your choice. Keep in mind that configuration files are run in a specific order:
System-wide configuration files (such as /etc/profile) run first upon log in.
Configuration files specific to your Unix account (such as ~/.profile) run next if they’re available.
To look at your ksh configuration files:
1. | more /etc/profile ~/.profile Type more followed by the names of traditional Korn shell configuration files. You’ll see something similar to Code Listing 8.14. As before, look for any other filenames or ENV statements in the listings that would indicate other files that play a role in getting your ksh environment configured. |
2. | For your own information, list the system configuration files that your system uses and the order in which they’re called. For our system, we have

Code Listing 8.14. Look for file and path names or ENV statements in the configuration file listings (for the files you have) to identify all of the files that help set up your environment.
