edit your ~/.bashrc file. Mine looks like this:
Code:
# ~/.bashrc: executed by bash(1) for non-login shells.
export PS1='\h:\w\$ '
umask 022
# You may uncomment the following lines if you want `ls' to be colorized:
export LS_OPTIONS='--color=auto'
eval `dircolors`
alias ls='ls $LS_OPTIONS'
alias ll='ls $LS_OPTIONS -l'
alias l='ls $LS_OPTIONS -lA'
# Some more alias to avoid making mistakes:
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
