Running out of memory? Learn how Redis Enterprise enables large dataset analysis with the highest throughput and lowest latency while reducing costs over 75%! 

For the latter part of the week, I've been running some tests against Neo4j that generate a bunch of log files. I wanted to filter those files based on the time they were created to do some further analysis.

This is an example of what the directory listing looks like:

$ ls -alh foo/database-agent-*

But I wanted to split the files in half so that I could have the ones created before and after noon on June 23.

I discovered that this type of filtering is actually quite easy to do with the "find" command. So, if I want to get the files after noon, I could write the following:

$ find foo -name database-agent* -newermt "Jun 23, 2016 12:00" -ls

And to get the ones before noon:

Or we could even find the ones last modified between noon and 2 p.m.:

$ find foo -name database-agent* -not -newermt "Jun 23, 2016 14:00" -newermt "Jun 23, 2016 12:00" -ls

Or we can filter by relative time (e.g. to find the files last modified in the last one day, five hours):

$ find foo -name database-agent* -mtime -1d5h -ls
121939705        8 -rw-r--r--    1 markneedham      wheel                2524 23 Jun 14:00 foo/database-agent-mac17f73-1-logs-archive-201606231300176.tar.gz

There are lots of other flags you can pass to find but these ones did exactly what I wanted!
