<P>
When an interactive login shell starts, it automatically executes
one or more pre-defined files. Different shells execute different
files; see the documentation of each shell for further information.
<P>
Most shells first run some global file, for example, the Bourne
shell (<tt>/bin/sh</tt><A NAME="2708"> </A>) and its derivatives execute <tt>/etc/profile</tt><A NAME="2710"> </A>;
in addition, they execute <tt>.profile</tt><A NAME="2712"> </A> in the user's home directory.
<tt>/etc/profile</tt><A NAME="2714"> </A>
allows the system administrator to have set up a common user
environment, especially by setting the PATH to include local
command directories in addition to the normal ones. On the other
hand, <tt>.profile</tt><A NAME="2716"> </A> allows the user to customize the environment
to his own tastes by overriding, if necessary, the default
environment.
