variable assignments for the user environment.

starts.</para>

<para>It is recommended to use numerical prefixes for file names to simplify ordering.</para>

<para>For backwards compatibility, a symlink to <filename>/etc/environment</filename> is

installed, so this file is also parsed.</para>

<title>Configuration Format</title>
|
|
|
|
<para>The configuration files contain a list of
|
|
<literal><replaceable>KEY</replaceable>=<replaceable>VALUE</replaceable></literal> environment
|
|
variable assignments, separated by newlines. The right hand side of these assignments may
|
|
reference previously defined environment variables, using the <literal>${OTHER_KEY}</literal>
|
|
and <literal>$OTHER_KEY</literal> format. It is also possible to use
|
|
|
|
<literal>${<replaceable>FOO</replaceable>:-<replaceable>DEFAULT_VALUE</replaceable>}</literal>
|
|
to expand in the same way as <literal>${<replaceable>FOO</replaceable>}</literal> unless the
|
|
expansion would be empty, in which case it expands to <replaceable>DEFAULT_VALUE</replaceable>,
|
|
and use
|
|
<literal>${<replaceable>FOO</replaceable>:+<replaceable>ALTERNATE_VALUE</replaceable>}</literal>
|
|
to expand to <replaceable>ALTERNATE_VALUE</replaceable> as long as
|
|
<literal>${<replaceable>FOO</replaceable>}</literal> would have expanded to a non-empty value.
|
|
No other elements of shell syntax are supported.</para>
|
|
|
|
<para>Each <replaceable>KEY</replaceable> must be a valid variable name. Empty lines
|
|
and lines beginning with the comment character <literal>#</literal> are ignored.</para>
