In bash you can use two special characters regarding hostname:

• 
  h to get host name up to the first dot


• 
  H to get full host name

If you want anything else you need to make your own version for example with HOSTNAME variable:

[root@digi ]# HOSTNAME=digi.master01.usa.com # this should be set automatically by bash

[root@digi ]# PS1="[u@$HOSTNAME%.*.* ]#"
[root@digi.master01 ]#

  @yael you would need to add this to your ~/.bashrc file. E.g: add the line export PS1="[u@H ]#". Then logout or source the file, . ~/.bashrc to make this active.
