If you don't want ls colors at all, you can use "ls --color=never". You can set that up as an alias/function. If you DO want colors, just not the ones you're currently getting, then you need to look at the LS_COLORS environment variable.[trimmed interesting stuff about dircolors] My reading of the OP is that his ls output is not colorised, and he probably does *not* want to hand-roll some custom color semantics. He just wants to enable the behavior he remembers.
TLDR: I ate some dog food and it tasted to me like Felix probably does
need to do some hand-rolling after all.
So I open an xterm and enter
$ setterm --background blue --foreground white --bold on --store
setterm: terminal xterm does not support --store
and hit Ctrl-L. Blue sky, white fluffy characters.
With a foreboding sense of doom, I then cd to a directory with a
broken link and try
$ ls --color=auto
and get .... eww.
The attributes are reset. Everywhere that gets redrawn is reset to my
defaults (steelblue1 on black, and no bold). And with a second Ctrl-L
the darkness is complete.
Then I re-read the man page for setterm
--store
Stores the terminal's current rendering options (foreground and
background colors) as the values to be used at
reset-to-default. Virtual consoles only.
^^^^^^^^^^^^^^^^^^^^^
It does indeed work fine in a VT. But the default foreground color
(bold blue?) for directories is unfortunate, given Felix's background
color. (Adding -p to ls helps a little...not enough)
If I launch an xterm with
$ lxterm -bg blue -fg white
then there's no need to use "setterm --store" to fix the rendering
defaults for background/foreground. White-on-blue is then the default
and the "ls --color=auto" test succeeds, modulo the unfortunate
default directory foreground color.
As for setterm's "--bold on", I don't know whether there are
equivalent xterm switches.
