Automated Account & Principle Creation

[Dew Ediho]

I need to automate user account creation (useradd) in FreeBSD, I have
a list of user information in comma seperated file.

I also need to automate kerberos principle creation with the same set
of information.

any suggestions?

I have considered autoexpect  and perl, but is there a script out
there that already achieves the same goal?

Thanks.
