Tree View

[Sandeep]

hi list,

this is the first time i am posting in the list. i am working to create
a utility that rsyncs the desired folder of the volume to a sepecified
destination. i can get the list of all the folders in a particular
volume. the format i am getting is below
-------Format Begin-----
..
demo
demo/bulkmail
demo/images
demo/images/bulkmail
demo/productivity
demo/webpresence
errors
htmlasp
images
images/defaultlogo
info
info/htmlasp
info/images
info/mew
newsletter
newsletter/newyear05
newsletter/november04
newsletter/october04
newsletter/september04
others
photos
public_html
public_html/menu
-------Format End-----
and the tree structure is
..

thanks john, that was indeed helpful, thanks a lot. can you suggest

If you really want deep insight into regular expressions, you want
Jeffrey Friedle's "Mastering Reguar Expressions", now in its second
edition from O'Reilly (http://www.oreilly.com/catalog/regex2/).

It's not exclusively perl, but it is probably the most detailed book on
regular expressions you'll ever see.
