Well, from "The problem is that if the user is already in the userfile i have to say that he is already is an autovoice of an op or whatever." I have understood what I've typer earlier. Then if this not what you need the what you want? Be more precisly..

Then use something like this:

proc pub_addavoice {nick uhost hand channel text} {
global botnick
set person [lindex [split $text] 0]
if {$person == ""} {
puthelp "NOTICE $nick : You must give a nick to add. Use !addavoice <nick_to_be_added>"
return 0
}
set per_ip [getchanhost $person]
set per_host [maskhost $person!$per_ip]
set host [lindex [split $text] 1]
if {$host == ""} {
set host $per_host
}
set kadd [adduser $person $host]
if {$kadd == 1} {
chattr $person +h|+gv $channel
pushmode $channel +v $person
putserv "NOTICE $nick :Successfully added $person as an autovoice with host $host "
putserv "NOTICE $person :You were added to my user list by $nick as an autovoicesubop with host $host.Please set up y$
} (

if {$hand != "*"} {
if {[matchattr $hand -|g $channel]} {
putserv "NOTICE $nick :The user is already in the bot as an autovoice .."
return 0
}
if {[matchattr $hand -|o $channel]} {
putserv "NOTICE $nick :This user is already in the bots as an channelops .."
return 0
}
}
}
