Hi,
I want to delete all empty directories in a long directore tree structure. I want to use that from a script that will run on HP-UX 11. My definition of empty directory is that there is no regular file under it and directly beneath it. To elaborate, I have below directories.
/app/dev/java
/app/dev/java/src/
/app/dev/java/env
/app/dev/java/param
/app/dev/java/src/logger

There are two files -- ciim.dat at /app/dev/java/env and log.config under /app/dev/java/src/logger.
The scipt should delete only /app/dev/java/param and none else. This directory does not contain any file directly beneath it.
I could not make much progress searching on the web. Can you please help me ?
Thanks.

try this command and let me know whether it displays only the empty directory

Code:

find /app/dev/java -type d -empty

I responded to this reply today morning. Not sure if I missed to hit the sumbmit button!
I am geting error when using empty option. It says
find: bad option -empty

Can you please let me know any equivalent of empty compatible on HP-UX ?

try this

Code:

for v in targetdir/*; do [ $(ls -lA $v | wc -l) -eq 1 ] && rmdir $v; done;

That for-loop will never descend so it cannot determine if a chain of subdirectories is otherwise empty.

The only thing that's needed to solve this problem is a depth-first traversal.

Code:

find . -type d -depth -exec rmdir {} + 2>/dev/null

How about this (A bit of pseudocode):

Code:

for a in `find . -type d`; do
find a -type f
<If don't get anything>
rm -rf a

That approach would remove a directory which contains directories which contain files.
