If you’re reading this on GitHub, it may be out of date. The canonical copy of this repository lives on code.p1k3.com.
This repo is for dotfiles, utility scripts, and other things in my personal setup. Ideally, it includes most of the bits and pieces that make a personal machine usable for me. It may occasionally serve as a testbed for things that will eventually become standalone projects.
I generally use Debian and Debian-like GNU/Linux systems (including Ubuntu), with the xmonad tiling window manager rather than a full desktop environment like Gnome or KDE. I usually edit text in Vim, with Vimwiki for notes. I maintain a blog called p1k3 using wrt.
I have a partially-finished book about the command line which may be relevant.
As of February 2019, this collection is actively maintained, although it doesn’t meet the standards of quality, consistency, or documentation you might want from a real software project.
(Then again, neither do most software projects.)
Except as noted below or in the body of specific files, and to the extent possible under law, I, Brennen Bearnes, waive all copyright and related or neighboring rights to the contents of bpb-kit. Go to town.
home/bin/grab, written Tyler Cipriani, is probably GPLv3 or later, I’ll clarify that.
In the general case, I am a firm believer in Free Software, and correspondingly in the pragmatic value of strong copyleft licenses like the GNU General Public License. Where I have the option, I’ll generally license more substantial projects under the GPL, with a view towards impeding the corporate capture of every available computational resource and generally throwing a little grit in the gears of capital in these latter days before it finishes murdering the entire biosphere. (As no one uses my software, this is a purely symbolic gesture, but what the hell.)
People have invested a lot of time and effort in telling us the GPL is uncool, just as they’ve invested a lot of time and effort in promoting the practical business-friendly benefits of “Open Source” as a development methodology while tucking the political implications of Free Software away out of sight so as not upset the billionaires. These are not unrelated phenomena.
All that said, this is a trivial repository of configuration fragments and small utility scripts for a very limited audience. It seems likely to do the most good if nobody has to worry about the bureaucracy of grabbing bits and pieces of it.
From time to time, I may incorporate code from other sources in this collection, as long as it’s in the public domain or under a license that meets the Debian Free Software Guidelines. In those cases, I’ll do my best to ensure that said code is clearly marked.
I routinely thief ideas and bits of configuration from the following projects and people:
These days I use ZSH on personal systems and Bash when writing tutorials or doing tech support. I like to keep lots and lots of history. I think shell scripting is a nightmare for most real tasks, but I do it sometimes anyway.
.zshrc- nothing fancy
.sh_common- aliases and variables for both Bash and ZSH; no Bash compatibility guarantees here, since I mostly don’t use custom aliases in Bash
Scripts here fall into a handful of categories:
Many of these are unlikely to be portable, useful, or documented.

snowday: is it a snow day for the Boulder Valley School District?
ssh-nofucks: SSH to an address, I don’t really care if the key has changed
st: get status using myrepos

timeslice: aggregate some data for a given date range or file’s implied date
today: print a date
todaydir: find a p1k3 dir for the current date
uni: search unicode codepoint names (via @chneukirchen)

wip: move a p1k3 file into a work-in-progress directory
words: split input into individual words

xm: call xmodmap
xmonad.start: personal version of xmonad startup script
xtfix: do a subtle color shift within the current xterm
put-mv: stash a file path, copy or move it to the current directory
The fragments directory is for code snippets that I write in the course of testing some idea, checking a technique, or trying to solve a problem posed by friends on IRC.
They’re typically the kind of thing I’d throw in a random file called something
test.sh and overwrite later. It seemed useful to start collecting these
The cheatsheets directory is mostly empty, but may become a repository of useful shorthand documentation for the increasingly-many things I use that are not discoverable or memorable enough for my deteriorating long-term memory.
tmux for terminal multiplexing (i.e., most of what GNU Screen does).
In practice, this means that I rely on it for
.tmux.conf is brief, but does contain one useful
snippet for correcting weird Esc-key behavior in Vim.
.vimrc- see file for installation details
.hacksrcif it exists
.Xresourcestweaks xterm behavior and a number of fonts
.hacksrcis linked to
bin/xmonad.startfor a drop-in replacement for default XMonad startup on some Debian-like systems, including Gnome/Unity stuff and the like. Perpetually not-quite-right.
