Where Can I Find the Definition of $LS_COLORS?

Just a heads up, make sure you're looking for `LS_COLORS` in all uppercase! Some distributions may handle this differently. Also, you could strace the bash command to see where it’s being set; that might help!

Have you tried running this command? `PS4='+${BASH_SOURCE}:${LINENO}[$?]> ' bash -xli < /dev/null | grep LS_COLORS` to see what the output is.

It really depends on your operating system and setup. For example, I found that for my configuration, the variable is not set at all. You can check by running `set | fgrep -i LS_Colors`.

You might need to check if you're using `dircolors` somewhere. It’s a command that can set up the LS_COLORS variable for you. You can find more information about it in the manual here: https://man7.org/linux/man-pages/man1/dircolors.1.html.

You could also use this command to search your system: `grep -ir "LS_Colors" / 2>/dev/null`. It might help you locate where this variable is defined.
