ls -al –color /etc

Open the .bashrc file with your favorite text editor.
For example, you could type vi /root/.bashrc at the command line to open the file.

Under the line “# User specific aliases and functions” type:

alias ls=”ls -alh –color”
alias ll=”ls -alh –color”

Make sure to write your changes to the file and save them. The changes will not take effect until you close your terminal/session window and re-open a new terminal again.
