This is the finished release version of a script requested by simo, with extra options requested by Gulio.
You can see the original script request here http://forum.egghelp.org/viewtopic.php?t=20951


Code:

#####################################################################################
# Public Kick/Ban Script (with stored nick!uhost info & extended mute bans)
#
# pkb.tcl version 1.5 by SpiKe^^ (29July2021)
#####################################################################################
# This script saves the nick!uhost of everyone leaving the channel (quit/part/kick).
# The info is saved for 15 minutes & allows for setting a ban on a nick that is gone.
#
# This script will not target any protected nicks. Protected nicks are anyone who:
#   a)  is/was op or halfop in the target channel
#   b)  has a +o or +b access flag in the eggdrop userfile
#   c)  is/was in any one of the admin channels
#
# This script has 6 basic public commands (all 6 can be prefixed with a . or a !)
#   !kb nick     :kick and ban nick from the channel the command was typed in
#   !k nick      :kick nick from the channel the command was typed in
#   !b nick      :set a ban on nick in the command channel (use default ban_masktype)
#   !m nick      :set an extended mute ban on nick (use default mute_masktype)
#   !ub nick     :remove any and all bans/mutes keeping nick from joining/talking
#   !um nick     :remove any and all mutes keeping nick from talking
#
# There are also several command options for all of the public commands
#   !kb nick nick2 nick3     :kick and ban all listed nicks from the command channel
#   .k nick .A new reason    :set a new custom kick reason for this kick command
#   !b nick nick2 10         :set the ban time for these two bans to 10 minutes
#   .m #sumchannel nick      :change the target channel for this mute to #sumchannel
#   !kb #chan #chan2 nick    :kick/ban nick from both #chan and #chan2
#
# You can also set and remove specific ban masks
#   .kb nick!*@ahost.com *!me@*.host.org   :set 2 bans and kick any nicks that match
#   !b bart! @host.org 30    :set bans bart!*@* and *!*@host.org for 30 minutes
#

# set only username bans on these domains (ex. *!uid123457@*) #
set pkb(phosts) "*.irccloud.com *.mibbit.com *.kiwiirc.com *.8C39393E.IP"


# set one or more admin channels (or leave empty for no admin chan) #
# note: these channels must be limited access! everyone in these channels #
#         will have access to all the commands in this script. #
# note: all pkb commands done in these channels will apply to pkb(main_chan) #
set pkb(admin_chan) ""

# set one or more default target channels (or leave empty for no default chan) #
# note: these apply to all pkb commands done in a pkb(admin_chan) #

# change the number of minutes to store nick!uhost info (default = 15 minutes) #
# note: leave empty for default 15 min  (set 0 to not store any nick!uhost info) #
set pkb(store_time) ""

# when setting a ban, this script will check if isvoiced nick, and -v if needed #
#   0 = never mix modes -v and +b in the same mode command to the server #
#   1 = when possible, mix modes -v and +b in the same mode command to the server #

Greetz,

today in channel a chanop kickbanned someone (we use this version of stored hosts tcl)

and churail (wich is an anope services bot) beat eggbot setting ban wich is fine but eggbot sets a ban on the kickreason as well wich is odd since that is not a nick in channel:



Quote:

13:47:09 (&admin) : !kb Maidcaughtme Out!
13:47:10 Maidcaughtme Kicked from #channel By &Churail ( Out! )
13:47:10 &Churail Sets Mode on #channel to: +b *!*@cloaked-l1i8he.cable.virginm.net
13:47:10 @Falcon Sets Mode on #channel to: +b Out!*@*



churail is chanserv and falcon is the eggdrop

According to the most recent script header above, a dot is used for the separator between the nick(s) and the new kick reason...
Code:
#   .k nick .A new reason    :set a new custom kick reason for this kick command


Have your channel operator use the command as designed...
Quote:

!kb Maidcaughtme .Out!



Tip: Try changing the script triggers so they are not the same as your servers services bot triggers:)

but why does it set a ban on a non existing nick ?
from the code i believe there is a section that checks for that it works fine except when a char is used like out! for some reason it sets ban on that while if
!kb realnick out it doesnt set ban on out wich is the expected behaviour

Quote:


16:18:02 <+Simo> !kb Moseley out
16:18:03 Moseley Kicked from #test By &ChanServ ( out )
16:18:03 &ChanServ Sets Mode on #test to: +b *!*@sid-33643.lymington.irccloud.com
16:18:03 -Falcon- : out is not on channel #test
16:18:03 @Falcon Sets Mode on #test to: +b *!sid33643@*



am aware trigger is the same for chanserv and the tcl thats fine provided the tcl doesnt set bans on non existing nicks

That falls under this part of the scripts intended usage cases...
Code:
 # You can also set and remove specific ban masks
 #   .kb nick!*@ahost.com *!me@*.host.org   :set 2 bans and kick any nicks that match
 #   !b bart! @host.org 30    :set bans bart!*@* and *!*@host.org for 30 minutes


When using this "set and remove specific ban masks" part, the script must assume the operator wants to set or remove a specific ban.

Tip: Try changing the script triggers so they are not the same as your servers services bot triggers:)

so a non existing nick can get banned as well ?

as i expected the part that checks if nicks are in channel to trigger and halt bans on non existing nicks

the issue is not the trigger ! or . tho the issue is it sets bans on non existing nicks

There is no end to the number of ways an "operator" can misuse a command.

If they set a specific ban on a nick, or in your case a partial specific banmask, as that string does, the bot has no choice but to do as they asked.

That part of the script is working as intended and documented. Please feel free to remove or modify the "set and remove specific ban masks" part of the script.
Code:
    } elseif {[string match {*[!@]*} $item]} {
      if {[string match u* $do]} {  set orig $item  }

      set item [regsub -all -- {\*{2,}} $item {*}]
      set len [llength [set ils [split $item "!@"]]]

      if {$len == 2} {   incr len
        if {[string first "!" $item] > -1} {  lappend ils "*"
        } else {  set ils [linsert $ils 0 "*"]  }
      }

      if {$len == 3} {   lassign $ils n u h
        if {$n eq $mmpre} {  set n "${n}*"
        } elseif {$n eq ""} {  set n "*"  }
        if {$u eq ""} {  set u "*"  }
        if {$h eq ""} {  set h "*"  }
        set bmask $n!$u@$h
      } else {  set bmask $item  }

      if {![string match u* $do]} {
        if {$len > 3 || $bmask eq "*!*@*" || $bmask eq "$mmpre*!*@*"} {
          putserv "NOTICE $nk :Error: $item is not a valid user mask."
        } else {  lappend nickls $bmask  }
      } else {
        if {$bmask eq $orig} {  lappend nickls $orig
        } else {  lappend nickls "$orig $bmask"  }
      }
