Bash will do this for you. To have `prog' executed before each primary
prompt, do the following:
PROMPT_COMMAND=prog
Bash also expands a number of control strings in the prompt before it
is printed; if you want the prompt to change to include one of the
following it's not necessary to run a script
\t the time
\d the date
\n CRLF
\s the name of the shell
\w the current working directory
\W the last element of PWD
\u your username
\h the hostname
\# the command number of this command
\! the history number of this command
\$ a $ or a # if you are root
\<octal> character code in octal
\\ a backslash
