Dotfiles (Tom Ryder)
This is my personal repository of configuration files and scripts for `$HOME`,
including most of the settings that migrate well between machines.
$ git clone https://sanctum.geek.nz/code/dotfiles.git ~/.dotfiles
$ cd ~/.dotfiles
$ git submodule init
$ git submodule update
$ make -n install
$ make install
For the default `all` target, you'll need `bash(1)`, `make(1)`, and `m4(1)`.
The installation `Makefile` will overwrite things standing in the way of its
installed files without backing them up, so read the output of `make -n
install` before running `make install` to make sure you aren't going to lose
anything unexpected. If you're still not sure, install it in a temporary
directory so you can explore:
$ tmpdir=$(mktemp -d)
$ make install HOME="$tmpdir"
$ env -i HOME="$tmpdir" TERM="$TERM" bash -l
The default target will install the core terminal-only files: cURL, Git, GnuPG,
Vim, shell scripts and functions, and shell setup files. The remaining dotfiles
can be installed with the other targets. Take a look at the `Makefile` to see

The configurations for shells, GnuPG, Mutt, tmux, and Vim are the most
expansive, and most likely to be of interest. The i3 configuration is mostly
changed to make window switching behave like Vim windows and tmux panes do, and
there's a fair few resources defined for rxvt-unicode.
My `.profile` and other files in `sh` are written in POSIX shell script, so
they should work in most `sh(1)` implementations. Individual scripts called by
`.profile` are saved in `.profile.d` and iterated on login for ease of
management. Most of these boil down to exporting variables appropriate to the
system and the software it has available.
Configuration that should be sourced for all POSIX-fearing interactive shells
is kept in `~/.shrc`, with subscripts read from `~/.shrc.d`. There's a shim in
`~/.shinit` to act as `ENV`. I make an effort to target POSIX for my functions
and scripts where I can so that the same files can be loaded for all shells.
On GNU/Linux I use Bash, on BSD I use some variant of Korn Shell, preferably
`ksh93` if it's available.
As I occasionally have work on very old internal systems, my Bash is written to
work with [any version 2.05a or
newer](http://wiki.bash-hackers.org/scripting/bashchanges). This is why I use
older syntax for certain things such as appending items to arrays:
Compare this to the much nicer syntax available since 3.1-alpha1, which
actually works for arrays with sparse indices, unlike the above syntax:
Where I do use features that are only available in versions of Bash newer than
2.05a, such as newer `shopt` options or `PROMPT_DIRTRIM`, they are only run
after testing `BASH_VERSINFO` appropriately.
A terminal session with my prompt looks something like this:
~$ ssh remote
tom@remote:~$ cd .dotfiles
tom@remote:~/.dotfiles(master+!)$ git status
foobar: command not found
tom@remote:~/.dotfiles(master+!)<127>$ sleep 5 &
The username and hostname are elided if not connected via SSH. The working
directory is always shown. The rest of the prompt expands based on context to
include these elements in this order:
* Whether in a Git repository if applicable, and punctuation to show
repository status including reference to upstreams at a glance. Subversion
support can also be enabled (I need it at work), in which case a `git:` or
`svn:` prefix is added appropriately.
* The number of running background jobs, if non-zero.
* The exit status of the last command, if non-zero.
You can set `PROMPT_COLOR`, `PROMPT_PREFIX`, and `PROMPT_SUFFIX` too, which all
do about what you'd expect.
If you start up Bash, Ksh, or Zsh and it detects that it's not normally your
`$SHELL`, the prompt will display an appropriate prefix.
This is all managed within the `prompt` function. There's some mildly hacky
logic on `tput` codes included such that it should work correctly for most
common terminals using both `termcap(5)` and `terminfo(5)`, including \*BSD
systems. It's also designed to degrade gracefully for eight-color and no-color
If a function can be written in POSIX `sh` without too much hackery, I put it
in `sh/shrc.d` to be loaded by any POSIX interactive shell. Those include:
* Four functions for using a "marked" directory, which I find a more
manageable concept than the `pushd`/`popd` directory stack:
* `md()` marks a given (or the current) directory.
* `gd()` goes to the marked directory.
* `pmd()` prints the marked directory.
* `xd()` swaps the current and marked directories.
* Nine other directory management and navigation functions:
* `ad()` is a `cd` shortcut accepting targets like `/u/l/b` for
`/usr/local/bin`, as long as they are unique.
* `bd()` changes into a named ancestor of the current directory.
* `mkcd()` creates a directory and changes into it.
* `pd()` changes to the argument's parent directory.
* `rd()` replaces the first instance of its first argument with its
second argument in `$PWD`, emulating a feature of the Zsh `cd` builtin
that I like.
* `scr()` creates a temporary directory and changes into it.
* `sd()` changes into a sibling of the current directory.
* `ud()` changes into an indexed ancestor of a directory.
* `vr()` tries to change to the root directory of a source control
* `bc()` silences startup messages from GNU `bc(1)`.
* `ed()` tries to get verbose error messages, a prompt, and a Readline
environment for `ed(1)`.
* `env()` sorts the output of `env(1)` if it was invoked with no arguments,
just for convenience when running it interactively.
* `gdb()` silences startup messages from `gdb(1)`.
* `gpg()` quietens `gpg(1)` down for most commands.
* `grep()` tries to apply color and other options good for interactive use if
* `hgrep()` allows searching `$HISTFILE`.
* `keychain()` keeps `$GPG_TTY` up to date if a GnuPG agent is available.
* `ls()` tries to apply color and other options good for interactive use if
* `la()` runs `ls -A` if it can, or `ls -a` otherwise.
* `ll()` runs `ls -Al` if it can, or `ls -al` otherwise.
* `mysql()` allows shortcuts to MySQL configuration files stored in
* `path()` manages the contents of `PATH` conveniently.
* `scp()` tries to detect forgotten hostnames in `scp(1)` command calls.
* `sudo()` forces `-H` for `sudo(8)` calls so that `$HOME` is never
preserved; I hate having `root`-owned files in my home directory.
* `tree()` colorizes GNU `tree(1)` output if possible (without having
* `vim()` defines three functions to always use `vim(1)` as my `ex(1)`,
`vi(1)` and `view(1)` implementation if it's available.
* `x()` is a one-key shortcut for `exec startx`.
There are a few other little tricks defined for other shells providing
non-POSIX features, as compatibility allows:
* `keep()` stores ad-hoc shell functions and variables (Bash, Korn Shell 93,
* `prompt()` sets up my interactive prompt (Bash, Korn Shell, Z shell).
* `pushd()` adds a default destination of `$HOME` to the `pushd` builtin
* `vared()` allows interactively editing a variable with Readline, emulating
a Zsh function I like by the same name (Bash).
* `ver()` prints the current shell's version information (Bash, Korn Shell,
Yash, Z shell).
I find the `bash-completion` package a bit too heavy for my tastes, and turn it
off using a stub file installed in `~/.config/bash_completion`. The majority of
the time I just want to complete paths anyway, and this makes for a quicker
startup without a lot of junk functions in my Bash namespace.
I do make some exceptions with completions defined in `.bash_completion.d`
files, for things I really do get tired of typing repeatedly:
* Bash builtins: commands, help topics, shell options, variables, etc.
* `find(1)`'s more portable options
* `ftp(1)` hostnames from `~/.netrc`
* `git(1)` subcommands, remotes, branches, tags, and addable files
* `gpg(1)` long options
* `make(1)` targets read from a `Makefile`
* `man(1)` page titles
* `mysql(1)` databases from `~/.mysql/*.cnf`
* `pass(1)` entries
* `ssh(1)` hostnames from `~/.ssh/config`
For commands that pretty much always want to operate on text, such as text file
or stream editors, I exclude special file types and extensions I know are
binary. I don't actually read the file, so this is more of a heuristic thing,
and sometimes it will get things wrong.
I also add completions for my own scripts and functions where useful. The
completions are dynamically loaded if Bash is version 4.0 or greater.
Otherwise, they're all loaded on startup.
#### Korn shell
These are experimental; they are mostly used to tinker with MirBSD `mksh`, AT&T
`ksh93`, and OpenBSD `pdksh`. All shells in this family default to a yellow
prompt if detected.
Just enough configuration to coax it into reading `~/.profile` and `~/.shrc`.
These are experimental; I do not like Zsh much at the moment. The files started
as a joke (`exec bash`). `zsh` shells default to having a prompt coloured cyan.
The configuration for GnuPG is intended to follow [RiseUp's OpenPGP best
The configuration file is rebuilt using `m4(1)` and `make(1)` because it
requires hard-coding a path to the SKS keyserver certificate authority, and
neither tilde nor `$HOME` expansion works for this.
My mail is kept in individual Maildirs under `~/Mail`, with `inbox` being where
most unfiltered mail is sent. I use
[MSMTP](http://msmtp.sourceforge.net/); the configurations for these are not
included here. I sign whenever I have some indication that the recipient might
be using a PGP implementation, and I encrypt whenever I have a public key
available for them. The GnuPG and S/MIME interfacing is done with
[GPGme](https://www.gnupg.org/related_software/gpgme/), rather than defining
commands for each crypto operation. I wrote [an article about this
setup](https://sanctum.geek.nz/arabesque/linux-crypto-email/) if it sounds
You'll need [Abook](http://abook.sourceforge.net/) installed if you want to use
the `query_command` I have defined, and [msmtp](http://msmtp.sourceforge.net/)
for the `sendmail` command.
I've butchered the URxvt Perl extensions `selection-to-clipboard` and
`selection` into a single `select` extension in `~/.urxvt/ext`, which is the
only extension I define in `~/.Xresources`.
The included `.Xresources` file assumes that `urxvt` can use 256 colors and
Perl extensions. If you're missing functionality, try changing
`perl-ext-common` to `default`.
My choice of font is [Ubuntu Mono](http://font.ubuntu.com/), but the file
should allow falling back to the more common [Deja Vu Sans
Mono](http://dejavu-fonts.org/wiki/Main_Page). I've found
[Terminus](http://terminus-font.sourceforge.net/) works well too, but bitmap
fonts are not really my cup of tea. The Lohit Kannada font bit is purely to
make ಠ\_ಠ work correctly. ( ͡° ͜ʖ ͡°) seems to work out of the box.
These are just generally vi-friendly settings, not much out of the ordinary.
Note that the configuration presently uses a hard-coded 256-color colorscheme,
and uses non-login shells, with an attempt to control the environment to stop
shells thinking they have access to an X display.
The configuration file is created with `m4(1)` to allow specifying a color
theme. This is just because I use a different color for my work session. The
default is a dark grey.
The configuration for Bash includes a `tmux` function designed to make `attach`
into the default command if no arguments are given and sessions do already
exist. The default command is normally `new-session`.
My `~/.inputrc` file binds Alt+M to attach to or create a `tmux` session, and
Tmux in turn binds the same key combination to detach.
The majority of the `.vimrc` file is just setting options, with a few mappings.
I try not to deviate too much from the Vim defaults behaviour in terms of
interactive behavior and keybindings.
The configuration is extensively commented, mostly because I was reading
through it one day and realised I'd forgotten what half of it did. Plugins are
loaded using @tpope's [pathogen.vim](https://github.com/tpope/vim-pathogen).
Where practical, I make short scripts into POSIX (but not Bourne) `sh(1)`,
`awk(1)`, or `sed(1)` scripts in `~/.local/bin`. I try to use shell functions
only when I actually need to, which tends to be when I need to tinker with the
namespace of the user's current shell.

* `zs(6df)` prepends "z" case-appropriately to every occurrence of "s" in the
text on its standard input.
The `install-bin` and `install-games` targets install manuals for each script
they install. There's also an `install-dotfiles-man` target that uses
`pandoc(1)` to reformat this document as a manual page for section 7
(`dotfiles(7df)`) if you want that. I haven't made that install by default,
because `pandoc(1)` is a bit heavy.
If you want to use the manuals, you may need to add `~/.local/share/man` to
your `~/.manpath` or `/etc/manpath` configuration, depending on your system.
You can check that both sets of shell scripts are syntactically correct with
`make check-bash`, `make check-sh`, or `make check` for everything including
the scripts in `bin` and `games`. There's no proper test suite for the actual
If you have [ShellCheck](https://www.shellcheck.net/) and/or
[Perl::Critic](http://perlcritic.com/), there's a `lint` target for the shell
script files and Perl files respectively. The files don't need to pass that
check to be installed.
Note for previous visitors
Most of this repository's five-year history was rewritten shortly after I moved
it from GitHub to cgit, taking advantage of the upheaval to reduce its size and
remove useless binary blobs and third-party stuff that I never should have
versioned anyway. If you've checked this out before, you'll probably need to do
it again, and per-commit links are likely to be broken. Sorry about that.
