I would like to copy all the files created in the last 12 months to a new folder leaving behind everything else. Including sub folders.

  • Strictly speaking, this is almost impossible; most *nix systems don't keep track of files' creation date/times.  You can, however, look at when they were last changed or modified. Apr 23 '15 at 3:13
  • By “including sub folders”, do you mean that they should be copied, that files in them should be copied, or that they should be left behind? Apr 24 '15 at 4:53

assuming you are ok with a flat destination folder (everything moved to the same place):

find /<top_level_folder> -type f -ctime -365 -exec cp -f {} /<new_folder_destination> \;

  • To get all files changed in the past year, use -ctime -365 (or perhaps -366). Apr 23 '15 at 3:15

  • You could also use -mtime instead of -ctime to get all files modified in the last year

  • Well, yes; as I (somewhat obscurely) point out in a comment on the question, there are two different ways of interpreting the question.  They are not equivalent. Apr 23 '15 at 3:39

    This question probably calls for -mtime, not -ctime. All kinds of things can change the ctime, such as changing permissions. If you want to find files created or modified in a certain date range, then the mtime is exactly right, under the reasonable assumption that it was not deliberately modified. Apr 24 '15 at 4:52
