Hi, We had an use-case where we had to list nodes matching a particular pattern from a given path. While looking at the ZK client commands, it seems that it does not support wildcard/regex.
I did try to overcome this by making some basic changes to the LSCommand.java and adding a "-m" switch which accepts regex. Since I implemented this using java.util.regex, it supports everything that Java regex supports. I was thinking such functionality can be useful for ls as well as delete (and deleteall). Though I implemented this at the client code for ls - this can be done at the server side code as well and I have a preliminary plan on top of my head to do this for ls, delete, deleteall. Will it be worthwhile addition to make to zookeeper? If so, I can open up a Jira, start a discussion on this and work on submitting a patch. -Vivek
