export PS1="e[0;31mue[0;37m@e[0;36mhe[0;37m:e[0;33mwe[0;37m:e[0;33m e0m > "

Take this apart:

• export PS1=" - is the command, it exports the command line PS1
• e[0;31m - changes the color to red
• u - this adds the user to the prompt (kennyl)
• e[0;37m - changes the color back to white
• @ - adds the @ symbol to the prompt (@)
• e[0;36m = changes the color to cyan
• h - adds the hostname to the prompt (magnum)
• e[0;37m - changes the color back to white
• : - adds a colon to the prompt (:)
• e[0;33m - changes the color to yellow
• w - displays the current working directory (~/Downloads)
• [0;37m - turns the color back to white again
• : - adds a colon to the prompt after the current directory (:)
• e[0m - turns the color back to the default
• > - adds a > to the end of the prompt (>)

The resulting prompt looks like this:

kennyl @ magnum : ~/Downloads : 17:01:00
