#### Add user virtual ftp
# NOTE: The entry will be placed in the file ftpd.passwd by default
# ftpasswd --uid UserID --gid GroupID --gecos "Full Name" --name UserName --shell /bin/false --home Path --passwd

#### Delete an entry from the file ftpd.passwd:
# ftpasswd --uid UserID --gid GroupID --gecos "Full Name" --name UserName --shell /bin/false --home Path --passwd --delete-user

#### Adding Groups and Group Membership to ftpd.group ####
# If used with --group, ftpasswd creates a file in the group(5) format,
# suitable for use with proftpd's AuthGroupFile configuration directive.

# NOTE: Using --group Default will write output to "./ftpd.group".

# --gid
# Primary group ID for this user (optional, will default to given --uid value if absent).

# --name
# Name of the user account (required). If the name does not exist in the specified output-file, an entry will be created
# for her. Otherwise, the given fields will be updated.

# --member
# User name to be a member of the group. This argument may be
# used multiple times to specify the full list of users to be members of this group.

# --delete-group
#  Remove the entry for the given group name from the file.

#### Add a group entry use the following command:
#  ftpasswd --gid GroupID --name GroupName --group

# NOTE: The entry will be placed in the file ftpd.group by default.

#### Delete an entry from the file ftpd.group:
#  ftpasswd --gid GroupID --name GroupName --group --delete-group

#### Add a member to a group:
#  ftpasswd --gid GroupID --name GroupName --member MemberName --group

#### Setting Permissions ####
# Set permissions on the ftpd.passwd and ftpd.group files:
# chmod 400 /etc/proftpd/ftpd.passwd /etc/proftpd/ftpd.group
# chown proftpd.nogroup /etc/proftpd/ftpd.passwd /etc/proftpd/ftpd.group
#
# NOTE: You can also add or remove members from groups or add and remove groups
# themselves by editing the file ftpd.group directly.

#### Start script ftpasswd
