Hi!
Section 12.1.12.1 _Are all system users necessary?_[1] suggests a
command intended to "easily find users who don't own any files":
cut -f 1 -d : /etc/passwd | \
while read i; do find / -user "$i" | grep -q . && echo "$i"; done
I tried it out, and it seems to do just the opposite. In other words,
it finds the users who *do* own files.
Substituting a || for && seems to fix the problem.
