I have files in the format YYYY_MM_DD_HH:MM:SS.swf that dump into a folder /home/user/dump/I want to move these files into a new directory tree /home/user/save/year/month/day/ based on the YYYY_MM_DD from the filename. Alternatively, if these can be modified by the file modification date, that is acceptable as well. I've found a couple other scripts on here, but they don't seem to have all the info I'm looking for.
Move files based on filename into directory Year/Month/Day
files;timestamps;mv
while read file do      f=$(basename $file)     year=$(echo $f|cut -f1 -d_)     day=$(echo $f|cut -f3 -d_)     month=$(echo $f|cut -f2 -d_)     new_dir=/home/user/save/$year/$month/$day     mkdir -p $new_dir     mv $file $new_dirdone < <(find /home/user/dump -type f -name *_*_*_*:*:*.swf)
