Question

It seems that ls doesn’t sort the files correctly when doing a recursive call:

ls -altR . | head -n 3

How can I find the most recently modified file in a directory (including subdirectories)?

Answer 1

find . -type f -printf '%T@ %p\n' \
| sort -n | tail -1 | cut -f2- -d" "

For a huge tree, it might be hard for sort to keep everything in memory.

%T@ gives you the modification time like a unix timestamp, sort -n sorts numerically, tail -1 takes the last line (highest timestamp), cut -f2 -d" " cuts away the first field (the timestamp) from the output.

Edit: Just as -printf is probably GNU-only, ajreals usage of stat -c is too. Although it is possible to do the same on BSD, the options for formatting is different (-f "%m %N" it would seem)

And I missed the part of plural; if you want more then the latest file, just bump up the tail argument.
