jk_jailuser8
A utility to put an existing user in a jail
Usage
jk_jailuser [OPTIONS]
<username>
[more
usernames]
jk_jailuser --jail=/path/to/jail
<username>
Overview
The jk_jailuser utility will change the shell of an existing user <username> to jk_chrootsh and change the home directory to <jail>/./<previous-home-directory>, and it will add the user to <jail>/etc/passwd. On *BSD systems this is <jail>/etc/master.passwd and pwd_mkdb is used to generate the other password files.
The jk_jailuser utility will abort if the <jail>/etc/passwd file is missing, or if the shell is missing in the jail.
If <previous-home-directory> was already inside the jail, a /./ separator is placed on the correct location in the path. If the previous home directory was not in the jail, it is changed. In interactive mode you are asked if you want to move the contents. In non-interactive mode the contents are only moved if the --move option is specified.
Options

The jail directory to use. This jail should exist, and should have at least <jail>/etc/passwd
-

Will give verbose output
-
-h --help -

- -s --shell=shell
-
The shell to use inside the jail. Defaults to /usr/sbin/jk_lsh
