batchmode adding user accounts

[David Bear]

I have migrated a linux box to freebsd.  I would like to add all the
user accounts from linux to bsd but the format of /etc/passwd vs
master.password is problematic. 

what I would like to try is pull out the user id from my old passwd
file and somehow batchmode add them to my new system.  I can use awk
to get the old ids.  But is there utility that will accept a list of
user ids to add to master.password?
