How to list files that were changed in a certain range of time?

Using Gilles' solution and after reading the man find(1) again I found a more simple solution. The best option is the -newerXY. The m and t flags can be used.

m   The modification time of the file reference
t   reference is interpreted directly as a time

So the solution is

find . -type f -newermt 20111222 \! -newermt 20111225

The lower bound in inclusive, and upper bound is exclusive, so I added 1 day to it! And it is recursive. It works well on find v4.5.9.

Generally speaking, when you're looking for files in a directory and its subdirectories recursively, use find.

The easiest way to specify a date range with find is to create files at the boundaries of the range and use the -newer predicate.

touch -t 201112220000 start
touch -t 201112240000 stop
find . -newer start \! -newer stop

In addition to the answers already given, note that you can directly specify your dates:

find -type f -newermt "2011-12-22" \! -newermt "2011-12-24"

or

find -type f -newermt "2011-12-22 00:00:00" \! -newermt "2011-12-24 13:23:00"

if you additionally want to specify the time.
