Your X system uses a few dotfiles in your home directory to configure just about everything; they determine which X utilities and programs to run at startup, which window management system to use, and which fonts and colors you will see. Dealing with these files can be a little overwhelming if all you want to do is change the size of your font from young-programmer's size to middle-aged professor's size. We present Sample Dot Files in Appendix 6 and encourage you to modify our dotfiles to your preferences and system (but do keep backups). If you want to customize your display with something really personal, feel free to skim through the 600 page X User's Guide.
To see these and other normally invisible dot files, issue the
ls -a Unix command:
$ls -a List all files including dot ones. ./ .cshrc .mwmrc .xinitrc bin/ ../ .kshrc .profile Mail/ proj/ .Xdefaults .login .sh_history News/ src/
