The main man page you want to look at is passwd(5), which documents the
formats of the /etc/master.passwd and /etc/passwd file. In FreeBSD, the
master.passwd file is the equivilent of the shadow file in Linux. What
you want to do is convert the Linux password files to the master.passwd
file in FreeBSD, and then run
pwd_mkdb -p /etc/master.passwd
This will cause /etc/passwd to be built from /etc/master.passwd, and also
cause the rebuilding of two hash files that cache the user data in a
machine-readable format to improve performance, /etc/pwd.db (cache of
passwd) and /etc/spwd.db (cache of master.passwd). You can use the -C
argument to simply test if a file has the correct format and run sanity
checking, which is useful if you want to test a conversion without
possibly installing the results. Take a look at the pwd_mkdb(8) man page
for details.
