For the kind of thing you're talking about, you should use the
appropriate java classes.  Look at java.io.File.  Also, dig around on
search engines for "java reading directories".  I quickly found this;

which may help.

Now, if your example was merely a bad example, and you still have a
need to run external programs on linux, then you should check out the
'exec' method on class java.lang.Runtime.  It is a bit tricky to use
properly, but there is an excellent tutorial here;

Good luck.
