PS1

The following piece of code fits nicely in the /etc/profile file. It makes sure the PS1, the prompt is set in such a way, that you can see who is logged in at what system and what the current path is. At the same time it also sets the window title the same way. 

H=`uname -n`
if [ $(whoami) = "root" ] ; then
PS1='^[]2;${USER}@(${H}) ${PWD##/*/}^G^M${USER}@(${H}) ${PWD##/*/} # '
else
PS1='^[]2;${USER}@(${H}) ${PWD##/*/}^G^M${USER}@(${H}) ${PWD##/*/} $ '
fi
Note: to type the special characters, such as ^], you have to type first CRTL-V, and then CTRL-]. Likewise for ^G: type it as CTRL-V and then CTRL-G.

Second note: the escape characters only work properly when setting the window title using PuTTY. If you or any of your users use Reflection to access the servers, the escape codes don't work. In that case, shorten it to: 
if [ $(whoami) = "root" ] ; then
PS1='${USER}@(${H}) ${PWD##/*/} # '
else
PS1='${USER}@(${H}) ${PWD##/*/} $ '
fi
