Check whether the directory is empty or not

I am writing korn shell script in linux for some task.
As a part of it I want to check whether the directory is empty or not. If the directory is empty I just want to come out of the loop. Otherwise continue processing.

Is it the best way of testing by using  find command with emtpy option. What find will return in this case.

while(find /home/user/directory1 -empty -print)
do
//statement

done

Please suggest me a best solution for this

Thanks,
Radha.

the simplest and most effective way is to use ls command with -A option:

$ [ "$(ls -A /path/to/directory)" ] && echo "Not Empty" || echo "Empty"

or
$ [ "$(ls -A /tmp)" ] && echo "Not Empty" || echo "Empty"

or

Use if..else.fi in a shell script:

#!/bin/bash
FILE=""
DIR="/tmp"
# init
# look for empty dir
if [ "$(ls -A $DIR)" ]; then
     echo "Take action $DIR is not Empty"
else
    echo "$DIR is Empty"
fi
# rest of the logic

if [ "$(ls -l /path/to/dir | head -1)" = "total 0" ]
then
  dir is empty
else
  is not empty
fi

I am sorry for no reply for these many days.

What is the problem if I use find command with -empty option? Just to know the difference.

find dir1 -empty -print will display the names of all empty directories under the dir1 directory, but also any zero-length files found in a those directories.  If there are no subdirectories, and dir1 is empty, it will indeed return just dir1.  If dir1 has no subdirectories but is not empty and has no zero-length files, the find will return no data.  The "-print" is usually omitted (it is assumed for most common "find" statements).

If you know that there are no subdirectories in dir1, and that none of the files are zero-length, you could do something like:
if [ "$(find dir1 -empty)" = "" ]
then
    # the directory is not empty
    : do work for non-empty directory
done
