Execute shell script everytime a new user is created

Question

What would be the easiest way to execute a command everytime a new user is added?

I checked through /etc/adduser.conf but nothing is in there which looks like it will do this?

I thought about added it to the users .bashrc so it jsut executes when they login, but I would rather have it setup before they have logged in.

Any Help would be appreciated.

Answer 1

From man adduser:

   If  the  file  /usr/local/sbin/adduser.local exists, it will be exe‐
   cuted after the user account has been set up  in  order  to  do  any
   local setup.  The arguments passed to adduser.local are:
   username uid gid home-directory

Looks like you can add your user-creation actions here.

Answer 2

I did this some years ago writing a custom script that does everithing I need and calling adduser inside the script to add the user to the system.
