Seen on Slashdot…
Code:
# (bash syntax, alter appropriately. BTW, not intended for *your* .profile :)
export PS1="\nYou are in a room with many doors, all alike\n# "
alias cd="echo That door is locked #"
alias pwd="echo You are lost #"
alias ls="echo It is too dark to see anything #"
alias cat="echo It is too dark to see anything #"
alias vi="echo You\\'re not strong enough to perform that action #"
alias startx="echo I don\\'t understand #"
alias exit="echo You don\\'t know the way out #"
# And in case they try to remove their .profile...
alias rm="echo I\\'m sorry Dave, I\\'m afraid I can\\'t do that #"
