It's the first Jira I've created. Hopefully it is acceptable.

Good hunting down! The "^" is a valid regex symbol and hadoop-common's 'globbing' support adds a bit of regex support to itself. And since most FsShell funcs do glob matching by default, it is difficult to escape this from the shell. However, if you were to use a non globbing java API (pure FS.listStatus, instead of FS.globStatus) for doing the same operation in code with that string, it should work just fine. So while ^ is acceptable in DFS filenames, it means a different thing in the FsShell utils. Maybe adding a fix for this somehow (a glob switch?) can help in certain scenarios. Remember file a JIRA on this at https://issues.apache.org/jira/browse/HADOOP if you do want it fixed! :) -- Harsh J
