Yes. In your .bash_profile file, include a couple of lines like:
PS1='\h:s[\u] $PWD \$ '
export PS1
This sets the "prompt" so that it displays the computer's hostname (\h),
the shell you're using (\s), the name of the logged-in user (\u), and the
current working directory ($PWD) followed by a $ prompt. Some of the more
knowledgeable people might make suggestions for making this more
bullet-proof; I think the system may get confused as to the length of the
prompt which might cause wrapping problems etc unless other codes are
thrown in, etc. However, this prompt works for me.
You can experiment simply by typing at the prompt something like:
export PS1="$PWD"
and etc, then add the desired line to .bash_profile for future logins.
You can also take a look at man console_codes (or search in
www.linuxgazette.com for 2-cent tips concerning adding color to your
prompt) if you want to do such things as adding color to your prompt.
For example, on another machine I've got a prompt that looks like:
PS1="\[\n\t\]\n^[[44;01;33m\h[\u]:\$PWD^[[m\] "
which gives me the current time followed by a newline followed by the same
prompt mentioned above with yellow letters on a blue background. The ^[ is
a special escape sequence; I'm sorry, I don't remember how to enter that
sequence, maybe Ctrl-[ does it. At any rate, not all editors will let you
enter that sequence, but I did mine in vi.
