Hi Monks,

Let's say I have a text file that has svn list output like so: 

testing123/
foobar/
helloworld/
helloworld/r1/
helloworld/r1/helloworld-5-0.noarch.rpm
helloworld/r1/testfile23.txt
helloworld/r1/tomcat-7.0.27.rpm
helloworld/r2/
helloworld/r2/helloworld-2-0.noarch.rpm
helloworld/r2/testfile12.txt
helloworld/r2/tomcat-5.0.52.rpm
hellotest/

[download]

The file can be of any length. I basically want to identify the terminal directories in the tree. In the above example, I am looking to isolate: 

testing123/
foobar/
helloworld/r1/
helloworld/r2/
hellotest/

[download]

Any tips? I was thinking about reading the file into a hash or something, and then iterate the hash. I suspect I might need something like recursion. But recursion is my achilles heal. Never can grok it properly.

Any help would be much appreciated. Thanks.
