Re: Finding empty folders on IFS and QSH find

Thank you for this information. I have tested it and it is working for me.
To do an initial test I change rmdir to an echo.
Not very fluent in this scripting. trying to figure out the change so it
only searches the current level.

Thanks again.

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.

:wq! PoC
