Nifty things to put in your ~/.bashrc

# syntax highlighting less:
# sudo apt-get install source-highlight
# and comment out a line in ~/.bashrc that looks like this:
# [ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"
export LESS=" -R "
export LESSCLOSE="/usr/bin/lesspipe %s %s"
export LESSOPEN="| /usr/share/source-highlight/src-hilite-lesspipe.sh \"%s\""

# syntax-highlighting cat:
# sudo apt-get install python-pygments
alias ccat='pygmentize -g'

# Or, cat your stuff in rainbows!
# sudo gem install lolcat
alias cat=lolcat
