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

| 62 | <para>Most of the instructions below are used to create files located in
|

| 63 | the <filename class='directory'>/etc</filename> directory structure which
|
|---|
| 64 | requires you to execute the commands as the
|
|---|
| 65 | <systemitem class='username'>root</systemitem> user. If you elect to create
|
|---|
| 66 | the files in user's home directories instead, you should run the commands
|
