[Fedora-directory-users] Question on hierarchy tree deletion

[J. Hartman]

I can't remember how exactly I did it, but I recall I used awk and sort in
between to count the line length (awk) and do numeric sort on the resulting
line.

Something like this:

$ ldapsearch -b BASEDN "objectclass=*" | awk '/dn:/ {l=length($0);
sub(/dn:/,""); print l $0}' | sort -n | cut ... | ldapdelete ...

Gets a bit nasty but something like that should work.

Hope that helps!
