I realized my script for deleting users was not working properly. For some reason it did delete the user account from the system but did not use the 'userdel -r' command. I think I may have left some home directories in the system that are from old deleted accounts. Is there a command or way I can see what directories under /home are not tied to accounts that are in /etc/passwd?

here's a "base" way to do it
grep home /etc/passwd > file1
ls -b /home > file2
diff -y file1 file2

I'm sure you could clean this up by replacing the grep with an awk or sed command.

Code:
#!/bin/bash
for dir in /home/*
do
    grep -q ":$dir:" /etc/passwd && echo $dir is a home directory || echo $dir is not a home directory
done
