Re: Finding empty folders on IFS and QSH find

This works. find /home/kcrawford -type d

I am open to other solutions.

A simple shell-script will do also. I assume there are no blanks in the directory names!

Here, find generates a list of all directories starting from the current directory, listing the most nested directories first (so directories freeing directories can be probably identified as free, and deleted). For every entry, a "ls" command prints *all* entries, line by line. An empty directory has only two lines, two entries for . and .., so it's safe to assume that a directory with only two entries is empty and can be safely removed.

for DIR in `find . -depth -type d`; do
if [ `ls -1a ${DIR} |wc -l` -eq 2 ]; then
rmdir ${DIR}
fi
done

Tested in qsh with 7.2, no error messages. Can be used as one-liner, or saved in a *STMF with indents to help understanding at a later point in time. :-)

Important! The backticks are *not* apostrophes! You may see these like a braced expression in mathematics.
