SUMMARY:Weird find & rm behaviour

Thanks to all who gave inputs. Although most of the folks suggested using
-exec and find command combination, it did not work.

Since the NFS mounted filesystem was from IBM mainframe, I believe it has a
different file structure implementation(MVS file structure implementation).
Hence some incompatibilities.

By trial and error, I was able to find a way to overcome the problem. If the
NFS filesystem from IBM mainframe is mounted with "-noac" (no attribute
caching) option, the same old command worked.(# find . -type f -mtime +14
-print | xargs rm -f) .    -exec and find combination works too.

Here is a note from IBM's support knowledge base which MORE or LESS gives
some hint of the NFS problem.


  8) Symptom: Recursive Remove ( rm -rf ) does not always clean
     up the directory. Users receive "Directory not empty"
     messages and may need to issue the command again.
     Due to the uniqeness of MVS file architecture, it is not
     possible to make rm -rf work the same as Sun. Development
     tested and confirmed that this command does work with AIX
     using V2 NFS protocol.
