Gnome-terminal shows default coloring for files and directories but konsole doesn’t. Those who love Kubuntu always see this difference.Here is the simple trick to add the file highlighting in konsole.

alias ls=’ls –color=auto’

This will highlight the different colors for  ls output.To save this permanently for your konsole just add this line to bash.bashrc file.

sudo vi /etc/bash.bashrc 

Add ls=’ls –color=auto’ at the end of bash.bashrc file.And you are done.
