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
[73e1db21]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>
[3f8be484]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
[c58eb217]40 invoked as an interactive login shell. Create a base
[56155f9]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
[c58eb217]44 sets the <envar>INPUTRC</envar> environment variable that makes Bash and
