<title>The Bash Shell Startup Files</title>
|
|
|
|
<para>The shell program <filename>/bin/bash</filename> (hereafter
|
|
referred to as just "the shell") uses a collection of startup files to
|
|
help create an environment. Each file has a specific use and
|
|
may affect login and interactive environments differently. The files in
|
|
the <filename class="directory">/etc</filename> directory generally provide
|
|
global settings. If an equivalent file exists in your home directory it may
|
|
override the global settings.
|
|
</para>
|
|
|
|
<para>An interactive login shell is started after a successful login, using
|
|
<filename>/bin/login</filename>, by reading the <filename>/etc/passwd</filename>
|
|
file. This shell invocation normally reads <filename>/etc/profile</filename>
|
|
and its private equivalent <filename>~/.bash_profile</filename> upon
|
|
startup.</para>
|
|
|
|
<para>An interactive non-login shell is normally started at the command-line
|
|
(e.g., <prompt>[prompt]$</prompt><command>/bin/bash</command>) or by the
|
|
<command>/bin/su</command> command. An interactive non-login shell is also
|
|
started with a terminal program such as <command>xterm</command> or
|
|
<command>konsole</command> from within a graphical environment. This type of
|
|
shell invocation normally copies the parent environment and then reads the
|
|
user's <filename>~/.bashrc</filename> file for additional startup configuration
|
|
instructions.</para>
|
|
|
|
<para>A non-interactive shell is usually present when a shell script is
|
|
running. It is non-interactive because it is processing a script and not
|
|
waiting for user input between commands. For these shell invocations, only
|
|
the environment inherited from the parent shell is used.</para>
|
|
|
|
<para> The file <filename>~/.bash_logout</filename> is not used for an
|
|
invocation of the shell. It is read and executed when a user exits from an
|
|
interactive login shell.</para>
|
|
|
|
<para>To the standard files, <filename>/etc/bashrc</filename> is called from
|
|
the user's <filename>~/.bashrc</filename> for system wide initialization of
|
|
non-login shells.</para>

<para>Here is a base <filename>/etc/profile</filename>. This file starts by
|
|
setting up some helper functions and some basic parameters. It specifies some
|
|
<filename>bash</filename> history parameters and, for security purposes,
|
|
disables keeping a permanent history file for the root user. It also sets a
|
|
default user prompt. It then calls small, single purpose scripts in the
|
|
<filename class='directory'>/etc/profile.d</filename> directory to provide most
|
|
initialization. </para>
