This prompt is color-scheme-able. You can invoke it thus:
|
||||
|
||||
prompt adam2 [ simple ] <color1> <color2> <color3>
|
||||
prompt adam2 [ 8bit ] [<color1> [<color2> [<color3>] [<color4>]]
|

where the colors are for the hyphens, current directory, and user@host
|
||||
bits respectively.
|
||||
where the colors are for the hyphens, current directory, user@host,
|
||||
and user input bits respectively. The default colors are cyan, green,
|
||||
cyan, and white. This theme works best with a dark background.
|
||||
|
||||
And you probably thought adam1 was overkill. If you've ever seen a
|
||||
more complex prompt in your whole life, please e-mail it to me at
|
||||
<adam@spiers.net>; I'd love to know that I'm not the saddest person
|
||||
on the planet.
|
||||
If you have the `nexus' or `vga' console fonts or similar, you
|
||||
can specify the `8bit' option to use 8-bit replacements for the
|
||||
7-bit characters.
