The following should really only get the uid's (not the gids, parts of a password, comments and what not): for uid in $(jot - 2001 3000); do \ grep -E "^[^:]+:[^:]+:$uid:" /etc/master.passwd; done This doesn't migrate home dirs, but using the above and piping to: cut -f 9 -d ':' should give you a list of home dirs to work with. -- Mel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

awk -F: '{if($4 > 3000) if($4 < 5000) print $0}' /etc/master.passwd
You should do it as root.

I'd probably sort /etc/master.passwd and pipe through awk:
sort -t ':' -k3,3n /etc/master.passwd | \
awk -F ':' '$3 ~ /^3[0-9][0-9][0-9]/, $3 ~ /^5/ { print }'
This will sort /etc/master.passwd numerically on the third field, uid, and
then give you all the lines starting with the first one where the uid is a
3 followed by at least three digits, up to and including the first one after
that where the first digit of the uid is a 5.
If you capture the output you should be able to merge it on the new host.

Then in theory cat accountstokeep.txt >> /etc/master.passwd followed by pwd_mkdb -p /etc/master.passwd should be enough. Again care should be taken that there are no conflicting accounts already in the /etc/master.passwd file. (a quick for uid in $(jot 2001 3000); do grep $uid /etc/master.passwd ; done on the new machine before adding to it should give you a quick check.) dont forget to ensure shells and home directories are available as needed Vince Thanks ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Re: password file migration
I did the same thing a long time ago and i just created used pwd_mkdb, and it worked fine. Though i'm not entirely sure what this has to do with this topic.

They are backwards compatible formats, so why do you want to change? If you are concerned that the old password hash is insecure (if it's an ancient DES password, this is true), then you will need to generate a new password for each affected account. One way to do this is by using password expiry to force a change on next user login (see e.g. pw(8)).
