linux changes directory display color instance detail

When listing directories in shell, the folders are all blue and the background is black, making it hard to see the blue file names. I have encountered this problem for several times and failed to record the solution, so I have to look up some information every time. This time, I decided to sort out this method so that I can use it in the future after encountering the same situation.

Solutions for files

To configure the current user, add the following parameters in the./bashrc directory of the current user home.

Here I simply changed the format of the folder to bold, the foreground color to yellow, the background color to black. There are also quotes in bold, cyan foreground, and black background. Here, focus on 1 di related parameters.

LS_COLORS='no=00:fi=00:di=01;33;40:ln=01;36;40:'
export LS_COLORS

See other articles that address the problem in the following ways

1. Copy /etc/DIR_COLORS file to.dir_colors of current home directory

 cp /etc/DIR_COLORS ~/.dir_colors

2. Modify the color corresponding to DIR in ~/.dir_colors

 vim ~/.dir_colors


  The first 59 Line: DIR 01;34 ( 01 : bold, 34 : blue)

  Is amended as: DIR 01;33 ( 01 : bold, 33 Yellow:)
