Full Discussion: Delete all files created in specific year
Top Forums UNIX for Beginners Questions & Answers Delete all files created in specific year Post 303036576 by drysdalk on Wednesday 3rd of July 2019 08:50:25 AM

Hi,

In theory, this should be fairly straightforward. If you want to delete all files created from 2017 and beyond (i.e. also files from 2016, 2015, etc - anything older than 2017), then you could do something like this:

Code:
find /path/to/files -type f -mtime +549 -exec rm -fv \{\} \;

That would find all files older than 549 days (at the time of writing, the number of days since December 31st 2017) and remove them.

Now, if you really want to only remove files from 2017, and only 2017, then it's slightly more complicated, but not much so. Assuming your version of find supports it, this would do the trick:

Code:
find /path/to/files -type f -newermt 2017-01-01 \! -newermt 2018-01-01 -exec rm -fv \{\} \;

This will very specifically remove files whose modification time is newer than 1st January 2017, but not newer than 1st January 2018 (in other words - files from 2017).

Hope this helps. Please test carefully before running this with a live rm command - swap it out for an ls or switch out the -exec for a -print first just to be sure it really is going to catch what you want, and only what you want, before turning this loose on your filesystem for real.
