Unix command to get list of directories over remote host

I am trying to do ssh to a remote machine and get list of directory names present at pathA(/home/abc/mydata) which has any file that has been modified in last 1 hours.

Directory:-

/home/abc/mydata
    -> Directory a
        ->file1   last modified 1 hour back
        ->file2   last modified 1 year back
        ->file3   last modified 1 day back
    -> Directory b
        ->file11  last modified 1 year back
        ->file22  last modified 1 year back
        ->file33  last modified 1 year back
        ->Directory b1
          ->fileb1-11 last modified 1 hour back
    -> Directory c
        ->file111  last modified 1 year back
        ->file222  last modified 1 year back
        ->file333  last modified 1 year back

I am trying to get output as

   a  => as it has 1 file which was modified 1 hour back(file1)
   b  => as it has 1 file under sub directory of directory b (fileb1-11)

I am trying the following command

         ssh "host" -t "find /home/abc/mydata -type d  -mmin -60 -ls"

however I want the final output as

  a
  b

but this command lists the sub directories also as the output.

  a
  b
  b1

Some help will be great.

Solution

Try:

ssh "$host" '
find /home/abc/mydata -mindepth 1 -maxdepth 1 -type d |
while read -r d; do
    [ "$(find "$d" -mmin -1 -type f -print -quit 2>/dev/null)" ] &&
    ls -ldi "$d"
done
'

Notes:

With mindepth/maxdepth, the first find will look only at level 1.
A separate find will look inside each subfolder for regular files (-type f) recently modified. If other recently modified file types (subdirectories/sockets/symlinks) should trigger the output, remove -type f.
The -t parameter to ssh is only necessary if you want colorized ls output.
The output of ls -ldi ... is slightly different from that of find ... -ls, but I'm guessing it will do.
The return value of the second level find is too vague to use here. Instead, we simply test if its output is nonempty.
