[SOLVED] Colours not displaying in bash prompt

Hi Everyone

I'm trying to configure URxvt to use the Solarized scheme by Ethan Schoonover, but I can't get colours to display in the bash prompt.  URxvt is clearly diplaying colours because vim is showing syntax highlighting nicely.

I'm missing something really fundamental here, but I don't know what it is.  Do I need to configure something in bash?

Here are my files (Yeah, pretty basic right now):

.Xresources

!! URxvt Settings ..............................................................

!! Use colours
URxvt.useColor:         true

!! Hide scroll bar
URxvt.scrollBar:        false

!! Colour Settings .............................................................

!! drop in Solarized colorscheme for Xresources/Xdefaults

Re: [SOLVED] Colours not displaying in bash prompt

Well ... you need to put colors in the prompt.

There are no color codes in your PS1.

edit: in retrospect I see this may look a bit abrupt.  I could instead give examples of how to put color codes into PS1, but there are so many examples out there I hope it is sufficient to point you in the right direction: the PS1= string needs to set which colors you want it to use, there are no defaults.  A quick googling will give plenty of examples.  Color codes will look like either \033[Xm or \e[Xm with X replaced by a suitable number (31-37 to get you started).  It's also good to enclose these in \[ \] pairs, any site with examples will probable explain why.

Re: [SOLVED] Colours not displaying in bash prompt

You can also get a bunch of ideas for fancy colored prompts in this thread: https://bbs.archlinux.org/viewtopic.php?id=50885

I like to define the colors before I use them so I don't have to use the messy escape sequences in the actual prompt:

RS="\[\033[0m\]"    # reset
HC="\[\033[1m\]"    # hicolor
FBLE="\[\033[34m\]" # foreground blue
FRED="\[\033[31m\]" # foreground red

PS1="$HC$FBLE\w$RS $ "
#PS1="$HC$FRED[\u:$FBLE\w]$RS# "

The first prompt is my normal user prompt, and the next one (commented out) I use in root's .bashrc.

Re: [SOLVED] Colours not displaying in bash prompt

Thanks for your replies, guys.

I realise I wasn't asking the right question.  I know how to modify my PS1, what I wanted to know was how (if it's possible) I can get coloured output in URxvt for commands like ls.  i.e. highlighting directories, files, executables, symlinks etc.

In retrospect, I don't know why I hadn't phrased my question like that.

Edit: @2ManyDogs, predefining colours is a nice tip!

See trapd00rs colours for an incredibly detailed example...
