+<title>The Bash Shell Startup Files</title>
 
-<para>NEW PAGE TO BE WRITTEN</para>
+<para>The shell program <filename>/bin/bash</filename> (hereafter
+refered to as just "the shell") uses a collection of startup files to
+help create an environment to run in.  Each file has a specific use and
+may affect login and interactive environments differently.</para>
+
+<para>An interactive login shell is started after a successful login by
+<filename>/bin/login</filename> by reading the /etc/passwd file.  An
+interactive non-login shell is started at the command line (e.g.
+[prompt]$<userinput>/bin/bash</userinput>).  A non-interactive shell is
+usually present when a shell script is running.  It is non-interactive
+because it is processing a script and not waiting for user input between
+commands.</para>
+
+<para>For more information see <filename>info bash</filename> -- Nodes:
+Bash Startup Files and Interactive Shells</para>
+
+<para>The following files are needed to make sure that the correct
+environment is read for each of the ways the shell can be invoked:
+<filename>/etc/profile</filename>, <filename>/etc/bashrc</filename>,
+<filename>~/.bash_profile</filename>, and
+<filename>~/.bashrc</filename>.  The file
+<filename>~/.bash_logout</filename> is not used for an invokation of the
+shell.  It is read by the shell when a user logouts of the system.  The
+files <filename>/etc/profile</filename> and
+<filename>~/.bash_profile</filename> are read when the shell is invoked
+as a interactive login shell.  The file <filename>~/.bashrc</filename>
+is read when the shell is invoked as an interactive non-login
+shell.</para> 
+
+<para>Here is a base <filename>/etc/profile</filename>.</para>
