coreutils ls color (was: another question...)

[Rodolfo Aramayo]

Ryan, Alexander,

Ok this is the deal.

To solve the problem you need to add the following into your: "/etc/profile
or ~.profile"

==========
PS1='\[\e]1;My Desk\a\e]2;${PWD}\a\
\e[0;34m\]\
[\t][\u at MYCOMPUTERNAME]\n \#\$ \
\[\e[m\]'
==========

Rationale:

Apple's good old "/bin/ls" is different from GNU's

In Apple's "/bin/ls" the flags are different. For example: ls -alFG gives
you a colorized output in the terminal, of course assuming you allowed color
to be used in: Terminal>Preferences>Settings>"Display ANSI colors"

In GNU's "/opt/local/bin/gls" the flag -G, which in Apple's is "Enable
colorized output" actually eliminates the -Group from the listing, -G =
--no-group and GNU's ls does not have a flag equivalent to the "-G" flag in
Apple's "ls"

Which explains why Groups were lost...on my listings

Simply installing coreutils changes nothing.

The terminal uses Apple's "ls", for example and "cat "and so on.

To use GNU's ls you need to either create an alias, example alias ls="gls"
OR what I did as recommended during the Ports installation, added the
"export PATH=/opt/local/libexec/gnubin:$PATH" to /etc/profile or ~.profile.

When you do that, Terminal replaces Apples basic stuff and uses GNU's "ls"
and other programs as specified in "/opt/local/libexec/gnubin/ls" for
example

As a result you lose color and as much as I tried, simply using: ls --color
does not work.

The confusing part  for me was that using ls -G was not working either for
reasons explained above.

Yes there is a ton of documentation about "dircolors" and LS_COLOR and
--color, but I was unable to get that to work.

I am sure there is a way, but I could not find it...

So that is it and I Thank Doug Barton for his guidance (
