How to delete particular files in a directory?

ipjyo asked
Last Modified: 2012-05-11

I have two types of files in a directory as below. Both of them are text files but distinguished by the name prefix "PST" or "SEQ".

PST-051311, PST-051211 etc
SEQ-051311, SEQ-051211, SEQ-051011 etc

I need to look at the directory and for each of those files that start with SEQ, get the date part after the hyphen and if there is no PST file with the same date after the hyphen then delete the SEQ file. In the above example, the file SEQ-051011 should be deleted.

I am looking for some ideas how to do this? Thanks for any ideas.
