Line 47 ⟶ 48:

The default {{Mono|modulefiles}} directory is empty initially. Copy the null module to the default modulefiles directory to have it shown by "module avail". The following uses the null and module-info modules to show use of a version file within a hierarchical organization and their effect on module avail and module show:

<syntaxhighlight lang="bash">

mkdir /etc/modulefiles/test

cp ${MODULESHOME}/modulefiles/null /etc/modulefiles/test/2.0

cp ${MODULESHOME}/modulefiles/module-info /etc/modulefiles/test/1.0

module avail

module show test

</syntaxhighlight>

Set the first version as the default:

<syntaxhighlight lang="bash">

echo '#%Module' > /etc/modulefiles/test/.version

echo 'set ModulesVersion "1.0"' >> /etc/modulefiles/test/.version

module avail

module show test

module show test/2.0

</syntaxhighlight>

Switch to the newer version as the default with:

<syntaxhighlight lang="bash">

rm /etc/modulefiles/test/.version

echo '#%Module' > /etc/modulefiles/test/.version

echo 'set ModulesVersion "2.0"' >> /etc/modulefiles/test/.version

module avail

module show test

</syntaxhighlight>
