If you're reading this on GitHub, it may be out of date. The canonical copy of this repository lives on

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 2020, 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.

a philosophical note about copying

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 have thiefed ideas and bits of configuration from the following projects and people:


shell stuff

These days I use ZSH on personal systems and Bash when writing tutorials, doing tech support, or working on production server systems. 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.

  • .bashrc
  • .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 in home/bin/

Scripts here fall into a handful of categories:

  • Short wrappers for getting (or remembering) specific behavior from other tools
  • Screenshot and screencast tools used in my work as a writer for DigitalOcean and Adafruit
  • Things for working with the p1k3 repo and site
  • Text filters and template fragments, mostly for use with Vim aliases
  • Miscellaneous utilities

Many of these are unlikely to be portable, useful, or documented.

  • cheat: a place to hang a personal cheatsheet of sorts
  • chrome-incognito: run Google Chrome in incognito mode
  • dmenu_unique: run dmenu with big fonts and vertical, only showing each entry once
  • dog: concatenate argument strings with stdin
  • edit-clipboard: edit the current text selection in $EDITOR (requires xclip)
  • enterprise: play a sound like the USS Enterprise engines in TNG
  • filter-decorate: splat some text dingbats into HTML I write sometimes
  • filter-exec: replace text in-between markers with result of shell-script execution
  • filter-exec-raw: like above, but different
  • filter-exec-stdin: feed text in-between markers to standard input of a command, replace it with output
  • filter-markdownify: convert a few things in old DigitalOcean tutorials to Markdown
  • filter-vertical: verticalize a string
  • firefox-fromselection: open a selected url in firefox
  • fragment-bullet: print out a "random" dingbat character
  • fragment-entry: stub blog entry
  • fragment-entry-gallery: stub blog entry with gallery
  • fragment-entry-poem: stub blog entry with poem
  • get-external-ip: print public IP address
  • gif-sel, gif-sel-4, gif-sel-15: take an animated gif of selected screen region
  • git-diff-wrapper: use vim with git-diff-tool
  • git-local-to-remote-status
  • grab, grab-sel: take a screenshot, take a screenshot of a selected region
  • json_decode.php: decode JSON into PHP data structures
  • pretty-print JSON with Perl
  • jump-to-window: use wmctrl and dmenu to pick a window to jump to
  • listusers: print an HTML list of users
  • lynx-wrapper-edit: edit a p1k3 entry in vim and re-render everything
  • machine-status: use dsh to check status on a list of machines (stub)
  • mostrecent: print the name of newest file in the current directory
  • notesession: start a tmux named session for notes
  • photocp: copy photos from various media to a home directory location
  • pmwhich: find the on-filesystem location of a Perl module
  • rightnow: print the current time in a variety of formats
  • saytime: speak the time with Festival
  • 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
  • timelog: parse a timelogging format (I use this to bill for contracting)
  • 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)
  • unsorted-unique: print all lines of input once (just an awk one-liner)
  • wip: move a p1k3 file into a work-in-progress directory
  • words: split input into individual words
  • wthr: use unicode snowflakes to display CPU load
  • xm: call xmodmap
  • xmonad.start: personal version of xmonad startup script
  • xtfix: do a subtle color shift within the current xterm
  • yank, put, 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 like and overwrite later. It seemed useful to start collecting these instead.


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.


I use tmux for terminal multiplexing (i.e., most of what GNU Screen does). In practice, this means that I rely on it for

  • persistent shell sessions, sometimes attached to multiple machines
  • putting a bunch of shell / editor buffers inside one ssh or mosh session
  • capturing and scrolling back through a bunch of output

My .tmux.conf is brief, but does contain one useful snippet for correcting weird Esc-key behavior in Vim.

vim config

  • .vimrc - see file for installation details
  • uses Vundle to manage plugins and such
  • pulls in a ton of plugins, some more useful than others

window management

  • .xmodmap
    • capslock -> ctrl
  • .xinitrc
    • sources .hacksrc if it exists
  • .Xresources tweaks xterm behavior and a number of fonts
    • behavior changes depending on whether .hacksrc is linked to .hacksrc_hi_dpi
  • XMonad config -
    • .xmobarrc, .xmonad/
    • see bin/xmonad.start for a drop-in replacement for default XMonad startup on some Debian-like systems, including Gnome/Unity stuff and the like. Perpetually not-quite-right.
