    1212<para>The shell program <command>/bin/bash</command> (hereafter
    13 referred to as just <quote>the shell</quote>) uses a collection of startup files to
    14 help create an environment to run in.  Each file has a specific use and
    15 may affect login and interactive environments differently.  The files in
    16 the <filename class="directory">/etc</filename> directory generally provide global
    17 settings. If an equivalent file exists in your home directory it may
    18 override the global settings.

    22 <command>/bin/login</command>, by reading the

    24 interactive non-login shell is started at the command-line (e.g.,

    26 shell is usually present when a shell script is running.  It is non-interactive
    27 because it is processing a script and not waiting for user input between
    28 commands.</para>

    96 writing direction. More complex cases (including UTF-8 based locales)
    97 require additional steps and additional patches because many applications
    98 tend to break in such conditions. Because of too little educational
    99 value for a typical reader, these steps and patches are not included
    100 in the LFS book and such locales are not supported by LFS in any way.
