       syslogout - modular centralized shell logout mechanism


       syslogout  is  a  generic  approach  to enable centralized shell logout
       actions for all users of a given system in a  modular  and  centralized
       way mostly aimed at avoiding work for lazy sysadmins.  It has only been
       tested to work with the bash shell.

       It basically consists of the small /etc/syslogout  shell  script  which
       invokes  other  small  shell  scripts  having  a .bash suffix which are
       contained in the /etc/syslogout.d/ directory.  The system administrator
       can  drop  in  any  script he wants without any naming convention other
       than that the scripts need to have a .bash suffix to  enable  automagic
       sourcing by the /etc/syslogout script.

       For  shell sessions, the contents of /etc/syslogout.d/" will be sourced
       by every user at logout if the  following  lines  are  present  in  his

           if [ -f /etc/syslogout ]; then
               . /etc/syslogout

       If  used for X sessions it is advisable to include the former statement
       into the Xreset script of the X display manager instead to prevent that
       closing  of  an  terminal  emulator window yields unexpected results in
       your running X session if your X11 terminal emulator is using  a  login
       shell.   Be  sure  then  to run it under the user-id of the X session’s
       user.   See  the  example  files   in   /usr/share/doc/syslogout/   for

       Users  not  wanting  /etc/syslogout to be sourced for their environment
       can easily disable it’s automatic mechanism.  It  can  be  disabled  by
       simply  creating  an empty file called $HOME/.nosyslogout in the user’s
       home directory using e.g. the touch(1) command.

       Any single  configuration  file  in  /etc/syslogout.d/  can  simply  be
       overridden  by  any  user  by  creating  a  private $HOME/.syslogout.d/
       directory which may contain a user’s own version of  any  configuration
       file to be sourced instead of the system default.  It’s names have just
       to match exactly the system’s default  /etc/syslogout.d/  configuration
       files.     Empty   versions   of   these   files   contained   in   the
       $HOME/.syslogout.d/ directory automatically  disable  sourcing  of  the
       system wide version.

       Naturally,  users  can  add and include their own private scripts to be
       automagically executed by /etc/syslogout at logout time.


       There are no options other than those dictated  by  shell  conventions.
       Anything is defined within the configuration scripts themselves.


       The    README   files   and   configuration   examples   contained   in
       /usr/share/doc/syslogout/ and the manual  page  for  bash(1),  xdm(1x),
       xdm.options(5), and wdm(1x).  Recommended further reading is everything
       related with shell programming.

       If you need a similar mechanism for executing code at login time  check
       out  the  related package sysprofile(8) which is a very close companion
       to syslogout.


       syslogout in its current form is mainly restricted to  bash(1)  syntax.
       In fact it is actually  a rather embarrassing quick and dirty hack than
       anything else - but it works.  It  serves the practical need to  enable
       a  centralized  bash  configuration   until  something  better  becomes
       available.  Your constructive criticism in making  this  into something
       better"  is  very  welcome.   Before  i  forget  to mention it: we take
       patches... ;-)


       syslogout   was   developed   by   Paul   Seelig   <>
       specifically  for the Debian GNU/Linux system.  Feel free to port it to
       and use it anywhere else under the conditions of either the GNU  public
       license or the BSD license or both.  Better yet, please help to make it
       into something more worthwhile than it currently is.
