« To find files in the /nas/images directory tree that are newer than the file /tmp/foo file, enter:

find /etc -newer /tmp/foo

You can use the touch command to set date timestamp you would like to search for, and then use -newer option as follows

touch --date "2010-01-05" /tmp/foo
# Find files newer than 2010/Jan/05, in /data/images
find /data/images -newer /tmp/foo »

Et donc, pour trouver des fichiers entre deux dates (ici entre janvier 2014 et avril 2014 inclus) :
touch --date "2014-04-30" /tmp/older
touch --date "2014-01-01" /tmp/newer
find . -newer /tmp/newer ! -newer /tmp/older
