ls --color

[Patrick Dupre]

Hello,

If I do

ls --color=auto -lt "$@" --color | more

and that the last displayed color is red,
this red color is used for all my following ls

How can I reset the color setting?

Thank

BTW, what's in "$@" ? For example.

That's odd, and does not seem like correct behaviour. Does it do it if 
you do not pipe through "more"?

I can't reproduce this (Ubuntu 21.04 here, not Fedora).

The --color is supposed to only control ls's decisions about how to 
colour the output. Does making the trailing --color either --color=never 
change anything?

Have you tried something like:

ls --color=auto -lt a b --color | od -c

i.e. exactly 2 filenames, the first or second or which will be "red", 
and examined the ANSI colour sequences in the (now small) output?

There _should_ be a "default colour" as the final colour sequence to 
reset the output to the terminal's default colours. That should be "ESC 
[ 0 m". Example:

[~]borg*> ls -ld --color=always . | od -c
     0000000   d   r   w   x   r   -   s   r   -   x       5   5       c   a
     0000020   m   e   r   o   n       c   a   m   e   r   o   n       8   1
     0000040   9   2       D   e   c           6       0   7   :   4   2
     0000060 033   [   0   m 033   [   0   1   ;   3   4   m   . 033   [   0
     0000100   m  \n
     0000102

See the "033 [ 0 m" sequence? That is the one which restore's the 
terminal's colour output the the default.

Cheers,

The help facility built into the ls command may be useful to you.

ls --help

I've tried your command in F37 and your issue doesn't occur for me 
potentially. In my situation the last colour displayed was blue for a 
directory, and when I issue the next ls command the first display is a 
directory in blue, followed by an image file in purple, a failed partial 
download in grey and files in white, which is exactly the same colour 
scheme as your command.
