|
---|
[f45b1953] | 4 |
|
---|
[b554263] | 5 | <para>The shell program <filename>/bin/bash</filename> (hereafter
|
---|
[64d97b7c] | 6 | referred to as just "the shell") uses a collection of startup files to
|
---|
[1a396398] | 7 | help create an environment. Each file has a specific use and
|
---|
[cfc2a54] | 8 | may affect login and interactive environments differently. The files in
|
---|
[8604d92f] | 9 | the <filename class="directory">/etc</filename> directory generally provide global
|
---|
[cfc2a54] | 10 | settings. If an equivalent file exists in your home directory it may
|
---|
| 11 | override the global settings.
|
---|
| 12 | </para>
|
---|
| 13 |
|
---|
| 14 | <para>An interactive login shell is started after a successful login, using
|
---|
[1a396398] | 15 | <filename>/bin/login</filename>, by reading the <filename>/etc/passwd</filename>
|
---|
| 16 | file. This shell invocation normally reads <filename>/etc/profile</filename>
|
---|
| 17 | and its private equivalent <filename>~/.bash_profile</filename> upon startup.</para>
|
---|
| 18 |
|
---|
| 19 | <para>An interactive non-login shell is normally started at the command-line
|
---|
| 20 | (e.g. <prompt>[prompt]$</prompt><command>/bin/bash</command>) or by the
|
---|
| 21 | <command>/bin/su</command> command. An interactive non-login shell is also
|
---|
| 22 | started with a terminal program such as <command>xterm</command> or
|
---|
| 23 | <command>konsole</command> from within a graphical environment. This type of
|
---|
| 24 | shell invocation normally copies the parent environment and then reads the
|
---|
| 25 | user's <filename>~/.bashrc</filename> file for additional startup configuration
|
---|
| 26 | instructions.</para>
|
---|
| 27 |
|
---|
| 28 | <para>A non-interactive shell is usually present when a shell script is
|
---|
| 29 | running. It is non-interactive because it is processing a script and not
|
---|
| 30 | waiting for user input between commands. For these shell invocatinos, only
|
---|
| 31 | the environment inherited form the parent shell is used.</para>
|
---|
| 32 |
|
---|
| 33 | <para> The file <filename>~/.bash_logout</filename> is not used for an
|
---|
| 34 | invocation of the shell. It is read and executed when a user exits from an
|
---|
| 35 | interactive login shell.</para>
|
---|
| 36 |
|
---|
| 37 | <para>To the standard files, we also add <filename>/etc/bashrc</filename>
|
---|
| 38 | which is called from the user's <filename>~/.bashrc</filename> for
|
---|
| 39 | system wide initialization of non-login shells.</para>
