11  <title>Setting The ${CLFS} Variable</title>
13  <para>Throughout this book, the environment variable <envar>CLFS</envar> will
14  be used several times. You should ensure that this variable is always defined
15  throughout the CLFS build process. It should be set to the name of the
16  directory where you will be building your CLFS system - we will use
17  <filename class="directory">/mnt/clfs</filename> as an example, but the
18  directory choice is up to you. If you are building CLFS on a separate
19  partition, this directory will be the mount point for the partition.
20  Choose a directory location and set the variable with the
21  following command:</para>
23<screen><userinput>export CLFS=<replaceable>[/mnt/clfs]</replaceable></userinput></screen>
25  <para>Having this variable set is beneficial in that commands such as
26  <command>install -dv ${CLFS}/tools</command> can be typed literally. The shell
27  will automatically replace <quote>${CLFS}</quote> with
28  <quote>/mnt/clfs</quote> (or whatever the variable was set to) when it
29  processes the command line.</para>
31  <para>Do not forget to check that <envar>${CLFS}</envar> is set whenever
32  you leave and reenter the current working environment (such as when doing a
33  <command>su</command> to <systemitem class="username">root</systemitem> or
34  another user). Check that the <envar>CLFS</envar> variable is set up
35  properly with:</para>
37<screen><userinput>echo ${CLFS}</userinput></screen>
39  <para>Make sure the output shows the path to your CLFS system's build
40  location, which is <filename class="directory">/mnt/clfs</filename> if the
41  provided example was followed. If the output is incorrect, use the command
42  given earlier on this  page to set <envar>${CLFS}</envar> to the correct
43  directory name.</para>
