dircolors issue

Perhaps a dummy question:
I noticed that on my Slackware box the output of dircolors looks like:

LS_COLORS=3D'no=3D00:fi=3D00:di=3D01;34:ln=3D01;36:pi=3D40;33:so=3D01;35

But on my Gentoo 2004.2 its only

The version on both is the same (fileutils 4.0). The real downer is
that I've updated my /etc/profile on the Gentoo box to make the same
statements as what the Slackware box says but it doesn't show me the
output of ls in color!? If, however, I login then run the commands it
will show the output in color. Isn't /etc/profile read each time bash
is invoked? Shouldn't it load my dircolrs? Do I need to add those
aliases? Seems odd, man ls says that if LS_OPTIONS is set that it will
use it by default, but seems not to.

Slackware patches ls & dircolors to do spiffier stuff than the rest of
us. Among other fanciness, Slackware adds those aliases you see in the
output of dircolors(1) and, presumably, that LS_OPTIONS variable you
mention. With any other distro, you will have to add those aliases
yourself.

I have something like the following in my .bashrc:

bashrc> eval $(dircolors -b /etc/DIR_COLORS)
bashrc> sl() { ls --color ${@+"$@"} ; }

You may find dir_colors(5) helpful. Be sure to read the manpages on your
Gentoo system, though. My version of ls(1) doesn't mention anything
about LS_OPTIONS.

No ;-)
Please, look at the bash man page, section "INVOCATION" (or info bash -> "Bash
Features" -> "Bash Startup Files").
Briefly:
-- when you login: /etc/profile -> ~/.bash_profile
-- when you open an xterm window: ~/.bashrc

The info page says: " So, typically, your `~/.bash_profile' contains the line
`if [ -f ~/.bashrc ]; then . ~/.bashrc; fi' "

So you should put something like

eval `dircolors -b /etc/DIR_COLORS`
alias l='ls -lF --color'
alias ll='ls -alF --color'

into your ~/.bashrc

and

[ -f ~/.bashrc ] && . ~/.bashrc

into your ~/.bash_profile.

You need LS_COLORS, which is set by dircolors -b /etc/DIR_COLORS.
