Linux shell terminal uses dircolors to manage the color scheme. To change the color setting for the ls output, we can do the following.
Step 1 Add the following into file ~/.bashrc so that the changes will be made permanent
if [ "$TERM" != "dump" ]; then
if [ -e $HOME/.dircolors ]; then
eval "`dircolors -b $HOME/.dircolors`"
fi
fi
Step 2 Print current color scheme and save it to file ~/.dircolors
dircolors -p >~/.dircolors
Step 3 Edit color settings for different file types as specified in file ~/.dircolors, e.g., change the color code for directory as "DIR 01;36" where 01 stands for bold font face and 36 indicates cyan for text color.
Step 4 Test the changes
source ~/.bashrc
ls -l ~/
