Re: some usefull command lines.

Also it would've been better if you had posted this in the Tips & Tricks session. Other than that, that list should prove useful to some of the new guys

Re: some usefull command lines.

@cc7046, I was just fearful that some newbies might think CrunchBang is still based on Ubuntu.. but I guess the big debian swirls should stop that

Re: some usefull command lines.

@cc7046 - I've add code tags to your post to make it more organized. Also I noticed lots of redundant commands in the first section and the package management section. You might wanna sort that out.

Only for LTS. I think the regular releases go so far as to use Unstable

Re: some usefull command lines.

yeah, long term has to be stable i suppose but run of the mill realease's maybe based on unstable, ie kubuntu 10.10 can be upgraded to kde 4.6 but cannot be done on kubuntu 10.04:)

Unless you update the repo's, which is kinnda pointless..........
