1) I have the following in my ~/.bashrc
# add a little color
alias lc="ls --color -F"
alias ll="ls -al"
alias llc="ls -al --color -F"
eval `dircolors -b`
The alias lines mean that if you type "ll" the output will be from "ls -al" and in color.
2) I had the same problem, the slack packages for these two are missing the install script, just go ahead and install them from source, thats what I did.
