Or you could use the -exec option to the find command as follows:
find -regextype posix-extended \
-regex '.*/P[A-Z0-9][0-9]{6}\.(jpg|JPG|jpeg)' \
-exec date --reference="{}" '+%Y%m' \;
What follows -exec is executed once for each file found. The {} is
replaced with the file name. Note the command must be terminated by an
escaped semi-colon, i.e., \;

Tony.
