16  <para>The shell program <command>/bin/bash</command> (hereafter
17  referred to as <quote>the shell</quote>) uses a collection of startup
18  files to help create an environment to run in. Each file has a
19  specific use and may affect login and interactive environments
20  differently. The files in the <filename class="directory">/etc</filename>
21  directory provide global settings. If an equivalent file exists in the
22  home directory, it may override the global settings.</para>
23
24  <para>An interactive login shell is started after a successful login,
25  using <command>/bin/login</command>, by reading the
26  <filename>/etc/passwd</filename> file. An interactive non-login shell
27  is started at the command-line (e.g.,
28  <prompt>[prompt]$</prompt><command>/bin/bash</command>). A
29  non-interactive shell is usually present when a shell script is
30  running. It is non-interactive because it is processing a script and
31  not waiting for user input between commands.</para>

38  <para>The files <filename>/etc/profile</filename> and
39  <filename>~/.bash_profile</filename> are read when the shell is
40  invoked as an interactive login shell. Create a base
41  <filename>/etc/profile</filename> that will read locale information from
42  <filename>/etc/locale.conf</filename> and load
43  any Bash auto completion files that may be on the system. This script also
44  sets the <envar>INPUTRC</envar> environment variable that makes Bash and
45  Readline use <filename>/etc/inputrc</filename>:</para>
