You can add as many directories as you want to the path. Just be sure
they are the complete directory and that each entry is separated by a
semi-colon.
This adds the user's name ( \u ), the at symbol ( @ ), the host's name
( \h ) and the current working directory ( \w ) to the prompt and makes
the prompt symbol the dollar sign ( $ ). It also changes the colours for
each of these. The user's name is now bold and red, the at symbol and
the host's name are now green, the working directory is cyan, the prompt
symbol is bold red and the command line text is white. Note that the
colour code appears before the various prompt additions.
