Regex help for catching all log patterns in a given unix dir?

Question

I have logs in a common landing directory as follows

12345_ABCZ_AA_Loader.20141218.095950941319000.log 12345_ABCZ_AA_Loader.20141218.095950941319000.log.1 12345_ABCZ_AA_Loader.20141218.095950941319000.log.2

12345_ABCZ_AA_BB_Loader.20141218.095950941319000.log

and some plain logs as well

SCheckReport.log

I need a regular expression which satisfies both requirements and grabs all logs for todays date.

Thanks

How about "."? It does satisfy all requirements you listed ... — Dima

Wont work as it picks too many files and not limited to just .log files — V R

exactly. So, there is nothing to filter out :) If your requirement is to only match ".log" files, you should have mentioned it in your question. In that case, the regex you are looking for is \.log Try to be more clear next time. There are not telepaths here. — Dima

While the question isn't exactly clear, this would match those Strings:

^(.*).log(.\d+)?$

EDIT: This doesn't look at todays date, but from your example, one of the filenames doesn't contain a date.

If you want the date, then use:

^(.*)20141218(.*).log(.\d+)?$

I'll leave it to you to build the regex String from current locale date.

Thanks for the quick response, Just to be clear if i needed files from the sample one to be picked for 20141218 what changes would i need to make to your regex (ignore plain sample 2).

I've edited the post to show the required regex for enforcing presence of the date. Use the 2nd regex statement in the answer. It passes a quick sanity check at RegexPal.
