I feel like `ls` or `find` and some creative sorting after the fact would do it. ls -laRrt sort of works, but it doesn't output subdirectory files in order. find doesn't have any sorting. You could use the `ls` flag `-D format`: When printing in the long (-l) format, use format to format the date and time output. The argument format is a string used by strftime(3). Depending on the choice of format string, this may result in a different number of columns in the output. This option overrides the -T option. This option is not defined in IEEE Std 1003.1-2001 (“POSIX.1”). Output the date as something that is more easily sortable, then pipe that through `sort -rn` and now you have a list of files in order of newest to oldest. Remove the directories with ` | egrep -v '^d'` and you've got a sorted list of files. Use `cut` to trim just the file path and you have a list of files. Maybe rsync can take in that list? Or you can use that list as an input for xargs or something? Get creative! web1 : / --> ls -lart -D '%Y%m%d%H%M%S' | sort -rnk 6 drwxrwxrwt 26 root wheel 323 20220427212946 tmp/ drwxr-xr-x 27 root wheel 117 20220415015709 etc/ drwxr-xr-x 21 root wheel 29 20200515173805 ./ drwxr-xr-x 21 root wheel 29 20200515173805 ../ -rw------- 1 root wheel 4096 20200515173805 entropy drwxr-xr-x 25 root wheel 25 20200515173804 var/ dr-xr-xr-x 11 root wheel 512 20200515173758 dev/ drwxr-xr-x 8 root wheel 8 20190830012952 data/ drwxr-xr-x 3 root wheel 3 20190830012952 zroot/ drwxr-xr-x 4 root wheel 17 20190510202515 root/ drwxr-xr-x 4 root wheel 61 20190303200651 lib/ drwxr-xr-x 16 root wheel 16 20190302233620 usr/ drwxr-xr-x 2 root wheel 150 20190302183503 rescue/ [...] On Wed, 27 Apr 2022, Andrea Venturoli wrote: > > Hello. > > Suppose I have a large storage of files and a smaller disk (backup). > I need to copy as much as I can from source to target and I want the most > recent files. > > Before I start scripting and reinvent the wheel, is there some tool already? > > bye & Thanks > av. > > --------------------------------------------------------------------------- Peter Beckman Internet Guy beckman@angryox.com https://www.angryox.com/ ---------------------------------------------------------------------------
