maybe...with any modification...
Code:
for element in $(ls -d *)
do
   if [ -d $element ]
   then
      echo "directory: $element"
      reciente=$(ls -lt $element | head -2 |tail -1)
      echo $reciente
   fi
done

What Operating System and version do you have. What shell(s) do you have available (e.g. ksh) ?

If this is unix rather than certain Linux variants it will not be possible to do what you require in one command. It will need a shell script.

I checked in Solaris and -P is not working u can use the find command without -P option
Code:
find . -name *.log -type f -mtime +1 -print 2>/dev/null

One way is to walk the tree then look at each directory for the newest file, taking into account that there may be non-files in the directory.


Code:
#!/bin/ksh
DIR_START="$1"
if [ "${DIR_START}""X" = "X" ]
then
        DIR_START="`pwd`"
fi
#
find "${DIR_START}/" -type d -follow -print | while read DIR
do
        # Look for newest file in directory (which is definitely a file)
        cd "${DIR}"
        ls -1t | while read FILENAME
        do
                if [ -f "${FILENAME}" ]
                then
                        ls -lad "${DIR}/${FILENAME}"
                        break
                fi
        done
done

Thanks guys!
albertogarcia and methyl - I've checked your code and both of them are exellent.
merajh - also this command fails in Solaris (version 10).
Probably, writing small code is better than one "find" command ...

Actually, you most definitely want to quote that glob, using "*.log" or '*.log' or \*.log. If unescaped, the shell expands that glob before the find command ever sees it. That command worked because there were no matches to *.log in the current directory, which from the looks of it is the top level /. When there are no matches, the shell leaves the pattern as is. Had there been one match, find would have been looking for a file with that specific name throughout the entire file hierarchy. Had there been multiple matches, the glob would've been expanded by the shell into a list and most likely would've lead to a find syntax error.

An illustrative example with sh tracing enabled (after `set -x`, each line beginning with a "+" is the command that the shell is actually executing):
Code:
$ mkdir tmp
$ cd tmp
$ ls -a
.       ..
$ set -x
$ find . -name *.log
+ find . -name '*.log'
$ touch 1.log
+ touch 1.log
$ find . -name *.log
+ find . -name 1.log
./1.log
$ touch 2.log
+ touch 2.log
$ find . -name *.log
+ find . -name 1.log 2.log
find: 2.log: unknown expression primary
$ find . -name \*.log
+ find . -name '*.log'
./1.log
./2.log
