Ubuntu :: Find Files With Directories And Sort By Mod Time?

what i wanted to do was find all the files with a specific name from a tree, sort them by modification time and have their directory appended to them so that i knew where they were (because they all have the same name). i tried a whole bunch of different things and finally did this:

Code:
find . -type f -name world.sav -exec ls -l '{}' ; > ~/dfsaves.txt; gawk '{$1=""; $2=""; $3=""; $4=""; $5=""; print}' ~/dfsaves.txt | sort -n > ~/dfsavessorted.txt

this did the trick pretty well, but as you can see it is far from elegant and i think i'm doing some things wrong and kludgy

first thing i tried was "ls -lRt | grep world.sav" which worked except i couldnt distinguish the files because there were no directories. that took a lot of looking till i accepted i couldnt make ls print directories as well and append them to the files somehow that their relationship would be clear. i tried piping ls to find, doing it in reverse, passing them from grep etc. etc. until i read some more stuff online that got me using gawk and sort. the questions:

1. is there some other, more elegant and simple way to do this kind of detection and sorting?

2. is there any way to use a pipe after using exec? the semicolon seems to prevent this entirely, forcing me to use an intermediate file as above. i could just remove it later, but i'd prefer a straight piping.
