15 <title>The Bash Shell Startup Files</title>
16
17 <para>
18 The shell program <filename>/bin/bash</filename> (hereafter referred to
19 as just "the shell") uses a collection of startup files to help create
20 an environment. Each file has a specific use and may affect login and
21 interactive environments differently. The files in the <filename
22 class="directory">/etc</filename> directory generally provide global
23 settings. If an equivalent file exists in your home directory it may
24 override the global settings.
25 </para>
26
27 <para>
28 An interactive login shell is started after a successful login, using
29 <filename>/bin/login</filename>, by reading the
30 <filename>/etc/passwd</filename> file. This shell invocation normally reads
31 <filename>/etc/profile</filename> and its private equivalent
32 <filename>~/.bash_profile</filename> (or <filename>~/.profile</filename>
33 if called as <command>/bin/sh</command>) upon startup.
34 </para>
35
36 <para>
37 An interactive non-login shell is normally started at the command-line
38 using a shell program (e.g.,
39 <prompt>[prompt]$</prompt><command>/bin/bash</command>) or by the
40 <command>/bin/su</command> command. An interactive non-login shell is also
41 started with a terminal program such as <command>xterm</command> or
42 <command>konsole</command> from within a graphical environment. This type
43 of shell invocation normally copies the parent environment and then reads
44 the user's <filename>~/.bashrc</filename> file for additional startup
45 configuration instructions.
46 </para>
47
48 <para>
49 A non-interactive shell is usually present when a shell script is
50 running. It is non-interactive because it is processing a script and not
51 waiting for user input between commands. For these shell invocations, only
52 the environment inherited from the parent shell is used.
53 </para>
54
55 <para>
56 The file <filename>~/.bash_logout</filename> is not used for an
57 invocation of the shell. It is read and executed when a user exits from an
58 interactive login shell.
59 </para>
60
61 <para>
62 Many distributions use <filename>/etc/bashrc</filename> for system wide
63 initialization of non-login shells. This file is usually called from the
64 user's <filename>~/.bashrc</filename> file and is not built directly into
65 <command>bash</command> itself. This convention is followed in this
66 section.

77 Most of the instructions below are used to create files located in the
78 <filename class='directory'>/etc</filename> directory structure which
79 requires you to execute the commands as the <systemitem
80 class='username'>root</systemitem> user. If you elect to create the
81 files in user's home directories instead, you should run the commands
82 as an unprivileged user.

97 Here is a base <filename>/etc/profile</filename>. This file starts by
98 setting up some helper functions and some basic parameters. It specifies
99 some <command>bash</command> history parameters and, for security
100 purposes, disables keeping a permanent history file for the <systemitem
101 class="username">root</systemitem> user. It also sets a default user
102 prompt. It then calls small, single purpose scripts in the <filename
103 class='directory'>/etc/profile.d</filename> directory to provide most
104 of the initialization.

227 Using the bash completion script below is controversial. Not all
228 users like it. It adds many (usually over 1000) lines to the bash
229 environment and makes it difficult to use the 'set' command to
230 examine simple environment variables. Omitting this script does
231 not interfere with the ability of bash to use the tab key for file
232 name completion.

643 This is because the clear is handled in the

672 If you want to use the <filename>dircolors</filename> capability, then
673 run the following command. The <filename class="directory">/etc/skel

675 a <filename>~/.dircolors</filename> file when a new user is set up.
676 As before, just change the output file name on the following command
677 and assure the permissions, owner, and group are correct on the files
678 created and/or copied.
