The prompt for bash shells can be changed by altering the PS1 variable.
PS1 can be declared in the global /etc/bashrc file or in ~/.bashrc.
My shell prompt looks like the following
[Sat Jun 30 15:32 andy@prosentia andy]>
The PS1 variable in my ~/.bashrc file looks like the following
PS1="[\d \t \u@\h \W]>"
\d is date
\t time
\u user
@\h @hostname
\W basename for current directory
the bash man file has details on different flags to alter the prompt
if your current directory was /usr/bin
PS1="me \W>" would show: me bin>
PS1="me \w>" would show: me /usr/bin>

ENVIRON(5) File Formats Manual ENVIRON(5)
NAME
environ - user environment
SYNOPSIS
extern char **environ;
DESCRIPTION
An array of strings called the `environment' is made available by exec(2) when a process begins. By convention these strings have the form
`name=value'. The following names are used by various commands:
PATH The sequence of directory prefixes that sh, time, nice(1), etc., apply in searching for a file known by an incomplete path name.
The prefixes are separated by `:'. Login(1) sets PATH=:/bin:/usr/bin.
HOME A user's login directory, set by login(1) from the password file passwd(5).
TERM The kind of terminal for which output is to be prepared. This information is used by commands, such as nroff or plot(1), which may
exploit special terminal capabilities. See term(7) for a list of terminal types.
Further names may be placed in the environment by the export command and `name=value' arguments in sh(1), or by exec(2). It is unwise to
conflict with certain Shell variables that are frequently exported by `.profile' files: MAIL, PS1, PS2, IFS.
