Delete Empty directories

DavidJ — Thu, 08 Feb 2007 04:20:01 GMT

Hi

Does anyone out there have a script which does a search and distroy for empty directories on your system?

The -empty option is not valid for "find" on HP-UX ;-(

David,
please see:

You can try the Perl sulution on a TEST filesystem. Seemed to work for me !

Or download gnu find and use the -empty option.

David,
bit slow at work here, so I put together this script. It may still need some fine tuning, so please test it first !

#!/usr/bin/sh
# Pull out a list of all directories
find . -depth -type d > /tmp/x.x
while read direc
do
# count the number of files in each directory
count=`ll -1a $direc | wc -l`
echo $direc $count
if [ $count -eq 3 ]
then
rmdir $direc
fi
done < /tmp/x.x
rm /tmp/x.x

Thanks Peter, I have similar shell script but was looking for something more 'eligant' and the perl script just did the trick. ;-) Ta

It seems you can just use find and rmdir and ignore the zillions of errors. I'm not sure if it is worth Peter's checking script:

find some-path -depth -type d -exec rmdir + 2>&1 | \
grep -v "rmdir.*Directory not empty"

Thanks All

The Perl script fits the bill perfectly.

perl -MFile::Find -e"finddepth(subrmdir},'.')"
