My humble apologies of this is a question beneath contempt in simplicity.

I am simply trying not to reinvent the wheel or oxcart here, and only come hither after weary hors on google in a fruitless pursuit.

What I am trying to do is sort out my copies of thousands of debian modules, keep the LATEST ones and move the older dups to another directory.

bar_123.10.0_deb foo_123.10.0_deb foo_123.2.8_deb

I can split by underscore, grab $2, split by dots, specially process or ignore $3 (and/or) $2 is it has anything non-mumeric - I'll deal with those another day.

I am looking for a 'uniq' type commad that will only spot foo (as having one or more duplicates on the first split $1 and then permit a real comparison of version numbers.

A simple sort may well fail here, for obvious reasons.

But... this is something that SHOULD HAVE been done many times before. I am certainly not requesting a script, but just a pointer to something I can learn from on this issue!

Perhaps it is already a module in the VCI::VCS libraries.

The problem for me is not as much in finding the answers, but learning to ask the right questions.....
