Dot Files

``Dot files'' are files which are named with an initial period rather than an alphanumeric character. These tend to be important files, but files which work in the background and that you don't ordinarily want to see or edit. Therefore, the simple command ls will not display these file names; you must use the -a option if you really want to see the dot files as well; ls -a

Some of your most important dot files, and what they do, are

.login
this file is read by the computer when you first log in. It tends to have commands that would only be of importance at the very beginning of a session; defining terminal type and display characteristics.

.profile
for those using the ``Korn shell'' this file gives information about where to find things (``PATH''), aliases, and other information which is used inside each text window and by other programs.

.kshrc
further information related to the Korn shell may be put here.

.plan and .project
Here is where you can put information that other folks can see when they use the command ``finger''.

.pinerc or .mailrc
depending on whether you use pine or mail to do your email, this is where your email configuration information is kept.

.netscape
this is a subdirectory of your home directory. Information about your preferences, bookmarks, and cache are kept here.

.exrc or .emacs
Configuration information for vi and emacs are kept in these files.

.newsrc
the list of Net News groups you subscribe to are kept here

.Xdefaults
Here is where to put your default information for the X Window System

.xinitrc
This file describes the initial arrangement of windows (xterms, clocks, buttons, etc.) you get when you start X.

.fvwm2rc
Here you can configure the window manager (fvwm2), defining what is in the root menu, what color frames get put on windows, what the L1-L10 and F1-F10 keys do, etc. If you use another window manager then the configuration file is named accordingly; .mwmrc for mwm, .twmrc for twm, etc.
