I have a text file in `/opt` which I would like to display to a particular user (e.g.: `/home/sunil`) during login (similar to welcome message).

I know about `/etc/motd` which displays the message for all users during login.

I don't want to use the respective users' `.cshrc`, `.bashrc` or `.profile` etc. because users will be added and deleted constantly.

Is it possible to display text to a particular user during login?
