Recursively delete only specified directories with given pattern

Hi All,

We have a requirement to recursively delete the directories and its subdirectories older than 60 days based on timestamp (folder creation timestamp)under certain directory. However it has some specific requirements.

The directories will continue to be there upto any depth.
the directories of concern are of the format / pattern as below

1) YYYYMMDD
2) YYYYMMDD_abcd
3) YYYYMMDD_abcd.1

The requirement is

1) Go through whole hierarchy to find out directories and recursively its subdirectories older than 60 days based on timestamp
2) If a pattern of YYYYMMDD is encountered, it should be deleted to the completely including all its sub directories
3) If a pattern of YYYYMMDD_abcd, YYYYMMDD_abcd.1 is encountered, it should not be deleted at all. Even the subdirctories under YYYYMMDD_abcd, YYYYMMDD_abcd.1 directories should not be deleted at all.

Currently we are using the following command to find relevant files

find /path/ -mtime +30 -type d -a ! -name "*_abcd*" -depth

however it is entering into the directories YYYYMMDD_abcd, YYYYMMDD_abcd.1 and listing down the subdirectories under them which we do not want it to enter into those directories.

Please advise and your help is highly appreciated. Thanks in advance.
