I use default Linux Mint .bashrc, here is full bashrc, the output is like:
some dir has green background, How to remove it?
To remove all background colors, stick the following into your ~/.bashrc :
eval "$(dircolors -p | \ sed 's/ 4[0-9];/ 01;/; s/;4[0-9];/;01;/g; s/;4[0-9] /;01 /' | \ dircolors /dev/stdin)"
