I have a bunch of operating system and distro-sensitive aliases for installing, removing and upgrading software using whatever package manager the system has:
<a href="https://github.com/eudoxia0/dotfiles/blob/master/home/.shell/sys.sh" rel="nofollow">https://github.com/eudoxia0/dotfiles/blob/master/home/.shell...</a>
It really depends on what you're looking for (more towards development or sys admin stuff?)<p>I started out with <a href="http://dotfiles.github.io/" rel="nofollow">http://dotfiles.github.io/</a> and then populated a Git repo from there.<p>Personally, I have things that make it easy to apply patches, create diffs, change to frequently used dirs and the likes.
Personally, I use `.` as an alias for a very flagged `ls`, and `..` as an alias for `cd .. && .`. It clobbers the existing `.` but it saves me a good bit of time navigating directories.
