shell - Create a "Recently Added Albums" m3u playlist -

i trying create playlist same idea "recently added albums" playlist see in itunes using $num_of_days_before parameter.

i've used ideas post: how recursively find , list latest modified files in directory subdirectories , times?

i've created script can run following params:

create_m3u /dir_root/with/mp3s 60 

where $1 directory root of mp3s (that have folders within have mp3s) $2 number of days backwards today i'd create m3u playlist file.

the main part of script command:

find $1 -type f -iregex '.*\.mp3' -mtime -$2 -exec stat --format '%y %y %n' {} \; | \ sort -n | \ cut -d' ' -f5- | \ sed -e 's/^/\./'  

now problem is, above command , including the

cut d' ' -f5- 

part gives me type of output:

which way want (partially) - sorted date when album added filesystem/pc. additionally want have each album sorted song number 01, 02, 03, 04... each folder/album , not unordered numbers seen above.

does have advice on how can differently can desired result?

your original command has redundancies - question linked requires date in output, whereas don't, can skip of fields being outputted stat. can skip stat using find -printf. should work (partly untested, sorry):

find $1 -type f -iregex '.*\.mp3' -mtime -$2 --printf "%t@~.%h~%f\n" |\ sort -t~ -nk1 -nk3 |\ cut -d~ -f2- |\ tr '~' '/' 

the find finds same files, prints out in following format:

[modified date in seconds since unix epoch]~.[file directory]~[filename] ex: 1234512345~./ratking - goes - 2014 [v0]~09. protein.mp3 

we sort firstly date, , secondly filename (both numerically, , using ~ field separator). strip off date field, replace remaining ~ forward slash give full file path.

note: work if files have track number @ beginning of filename, , not give correct results file ~ anywhere in file path (directory or filename). not chosen special reason, can replace more suitable character if necessary. character replacement required (as opposed using forward slash sort delimiter) (i assume!) level of subdirectory each file in potentially vary.
