From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I like this graphic, some of my favourites:

git log --oneline is super useful for getting just a list of title of commits and nothing else

git bisect is a little known but extremely useful git archaeology command that automates binary searching for a regression.

You're gonna love this then:

alias gl='git log --graph --abbrev-commit --no-decorate --date=format:'\''%Y-%m-%d %H:%M:%S'\'' --format=format:'\''%C(8)%>|(16)%h  %C(7)%ad  %C(8)%&lt;(16,trunc)%an  %C(auto)%d %>|(1)%s'\'' --all'

I have a whole rc file full of shortcuts like this for Git and Docker.

Nobody loves pedantic escaped single quoting more than I.

Except for you wow.

Show us the rc.

I just learned git bisect from https://ohmygit.org/! You run it, then checkout other commits all over the project, and mark them with git bisect good or git bisect bad. Then it paints all commits that led to the good one as good, and all the ones after the bad one as bad, so you just keep narrowing your window by playing checkout Jezzball until there's only one commit left: the one that introduced the bad state.

The technical term is binary search.

Yeah but I didn't know that term until I looked it up. Also OhMyGit didn't cover using tests and automating it.

Definitely a useful tool and one you should've learned in a college algorithms course. Binary search backs a lot of high performance data structures
