Add this to ~/.bashrc or ~/.bash_profile

- -- cut --
PS1='[\u@\h:\w]\$ '

# the \[ and \] surrounding the prompt tell bash to count the escaped 
characters
# properly
export TITLEBAR='\[\033]0;\u@\h:\w \007\]'

# Terminal sets TERM_PROGRAM so we can tell it apart from regular VT100
case "$TERM_PROGRAM" in
         "Apple_Terminal")PS1="$TITLEBAR$PS1"
esac

# xterm windows set TERM
case "$TERM" in
         
"xterm"|"vt100"|"color-xterm"|"xterm-color")PS1="$TITLEBAR$PSRAW"
esac

export PS1
- -- cut --

This will set your environment so that your username, what host the 
window is connected to, and the current directory are shown in the 
title bar of the Terminal window, in addition to at the command prompt. 
If you run X Window, xterms & color xterms will also show the 
information in the title bar.

Human beings will generally exercise power when they can get it, and 
they will exercise it most undoubtedly in popular governments under 
pretense of public safety.
