    11 <para>Create the <filename>/etc/profile</filename> file:</para>
     12<para>The shell program <command>/bin/bash</command> (hereafter
     13referred to as <quote>the shell</quote>) uses a collection of startup
     14files to help create an environment to run in. Each file has a
     15specific use and may effect login and interactive environments
     16differently. The files in the <filename
     17class="directory">/etc</filename> directory provide global settings.
     18If an equivalent file exists in the home directory, it may override
     19the global settings.</para>
     20
     21<para>An interactive login shell is started after a successful login,
     22using <command>/bin/login</command>, by reading the
     23<filename>/etc/passwd</filename> file. An interactive non-login shell
     24is started at the command-line (e.g.,
     25<prompt>[prompt]$</prompt><command>/bin/bash</command>). A
     26non-interactive shell is usually present when a shell script is
     27running. It is non-interactive because it is processing a script and
     28not waiting for user input between commands.</para>
     29
     30<para>For more information, see <command>info bash</command> - Nodes:
     31Bash Startup Files and Interactive Shells.</para>
     32
     33<para>The files <filename>/etc/profile</filename> and
     34<filename>~/.bash_profile</filename> are read when the shell is
     35invoked as an interactive login shell.</para>
     36
     37<para>A base <filename>/etc/profile</filename> below sets some
     38environment variables necessary for native language support. Setting
     39them properly results in:</para>
     40
     41<itemizedlist>
     42<listitem><para>The output of programs translated into the native
     43language</para></listitem>
     44<listitem><para>Correct classification of characters into letters,
     45digits and other classes. This is necessary for Bash to properly
     46accept non-ASCII characters in command lines in non-English
     47locales</para></listitem>
     48<listitem><para>The correct alphabetical sorting order for the
     49country</para></listitem>
     50<listitem><para>Appropriate default paper size</para></listitem>
     51<listitem><para>Correct formatting of monetary, time, and date
     52values</para></listitem>
     53</itemizedlist>
     54
     55<para>This script also sets the <envar>INPUTRC</envar>
     56environment variable that makes <application>Bash</application> and
     57<application>Readline</application> use the
     58<filename>/etc/inputrc</filename> file created earlier.</para>
     59
     60<para>Replace <replaceable>[ll]</replaceable> below with the
     61two-letter code for the desired language (e.g., <quote>en</quote>) and
     62<replaceable>[CC]</replaceable> with the two-letter code for the
     63appropriate country (e.g., <quote>GB</quote>). It may also be
     64necessary to specify (and this is actually the preferred form) the
     65character encoding (e.g.  <quote>iso8859-1</quote>) after a dot (so
     66that the result is <quote>en_GB.iso8859-1</quote>).  Issue the
     67following command for more information:</para>
     68
     69<screen><userinput>man 3 setlocale</userinput></screen>
     70
     71<para>The list of all locales supported by Glibc can be obtained by running
     72the following command:</para>
     73
     74<screen><userinput>locale -a</userinput></screen>
     75
     76<para>Once the proper locale settings have been determined, create the
     77<filename>/etc/profile</filename> file:</para>
    1278
    1379<screen><userinput>cat &gt; /etc/profile &lt;&lt; "EOF"
    … …  
    2187EOF</userinput></screen>
    2288
     89<note><para>The <quote>C</quote> (default) and <quote>en_US</quote>
     90(the recommended one for United States English users) locales are
     91different.</para></note>
     92
     93<para>Setting the keyboard layout, screen font, and
     94locale-related environment variables are the only internationalization
     95steps needed to support locales that use ordinary single-byte
     96encodings and left-to-right writing direction. More complex cases
     97(including UTF-8 based locales) require additional steps and
     98additional patches because many applications tend to not work properly
     99under such conditions.  These steps and patches are not included in
     100the LFS book and such locales are not supported by LFS in any
     101way.</para>
