Try Test Filesystem

Check the plugin descriptor for the plugin that includes the command. Do you see a line of the form

&ltalias name="AllFSTest" class="org.jnode.some.ClassName">

If you can add the alias permanently by editing the descriptor and rebuilding, temporarily using the "alias" command.

Alternatively, you should be able to run the command using its fully qualified className.

Can you explain me how can I check the plugin descriptor please?

I have tried in the folder of the code source

[vinicio@localhost jnode]$ grep -R AllFSTest *
./fs/build.xml:
The only file ./fs/build.xml seem have the key word "AllFSTest"

After inside the file ./fs/build.xml i see:
&l ttarget name="tests" depends="compile" description="Run FS tests with JUnit">
&lt junit fork="yes" haltonerror="false" haltonfailure="false" printsummary="on" includeantruntime="true">
&lt classpath refid="cp-jnode" />
&lt formatter type="plain" usefile="false" />
&lt test name="org.jnode.test.fs.AllFSTest" />
...

After I entered the command:
[vinicio@localhost jnode]$ grep -R alias * | grep AllFSTest
The search result is empty
So I don't find any lines like:
&ltalias name="AllFSTest" class="org.jnode.some.ClassName">

(I'm not on my dev't box at the moment ... so searching the tree is a bit hard ...)

The build.xml reference seems to imply that AllFSTest should be a JUnit test suite class that runs in your dev't sandbox. But I cannot see the class at all! (... I might be looking in the wrong place ... see above.) So I suspect that is the problem.

If this was a real command, should be looking for the alias in the plugin descriptors in "*/descriptors/*.xml". For example, the fs command plugin descriptor is in the file "fs/descriptors/org.jnode.fs.command.xml"
