## obligatory personal dotfiles repository
|
|
||||||
|
|
||||||
_(plus some little shell scripts)_
|
|
||||||
|
|
||||||
quick install for random boxes:
|
|
||||||
|
|
||||||
```
|
|
||||||
cd && curl -L https://github.com/notwa/rc/archive/master.tar.gz | tar zx && mv rc-master rc && rc/install
|
|
||||||
```
|
|
||||||
|
|
||||||
## stuff defined in RC files
|
|
||||||
|
|
||||||
such as [.bashrc](/home/bashrc) and [.zshrc](/home/zshrc)
|
|
||||||
but mostly [-shrc](/home/-shrc) and [.streamcrap](/home/streamcrap)
|
|
||||||
|
|
||||||
### reload
|
|
||||||
|
|
||||||
exec's the current shell.
|
|
||||||
if it's `zsh`, it'll also recompile `.zshrc` so everything actually reloads.
|
|
||||||
|
|
||||||
### ADDPATH
|
|
||||||
|
|
||||||
adds a directory to `$PATH` if it isn't already there.
|
|
||||||
|

||||||
### ify
|
|
||||||
|
|
||||||
pipes a command through another command, so you can pass arguments at the end as usual.
|
|
||||||
|
|
||||||
this is mainly useful for aliases. 99% of the time you'll use this with `less`.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ alias ll="ify less ls -ACX --group-directories-first --color=force"
|
|
||||||
$ ll /etc
|
|
||||||
```
|
|
||||||
|
|
||||||
### has
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
```
|
|
||||||
export CC="$(has clang || has clang-3.8 || has gcc)"
|
|
||||||
```
|
|
||||||
|
|
||||||
### revend
|
|
||||||
|
|
||||||
reverses the 4-byte endianness of a file. this is an in-place operation!
|
|
||||||
|
|
||||||
### nocom
|
|
||||||
|
|
||||||
strips lines that begin with a `#` character.
|
|
||||||
|
|
||||||
### jrep

|
||||||

|
|
||||||

e.g. this readme file.
|
|
||||||
|
|
||||||
### double

|
||||||
|
|
||||||

|
|
||||||
|
|

### join2

|
||||||
|
|
||||||
joins every other line.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ echo "hey\nyou\nout there\nwe bringing it live" | join2
|
|
||||||
hey you
|
|
||||||
out there we bringing it live
|
|
||||||
```
|
|
||||||
|
|
||||||
### katagana
|
|
||||||
|
|
||||||
converts katakana to hiragana.
|
|
||||||
useful for translating [debug text from ancient games.](https://tcrf.net/)
|
|
||||||
|
|
||||||
### picky + unused
|
|
||||||
|
|
||||||
attempts to find any non-standard packages that were installed
|
|
||||||
with pacman so that you can make note to install them, later,
|
|
||||||
on a fresh installation.
|
|
||||||
|
|
||||||
`unused` will print unused packages instead.
|
|
||||||
|
|
||||||
### makepkgf + rakef
|
|
||||||
|
|
||||||
make the freakin' package!
|
|
||||||
|
|
||||||
### trash

|
|
||||||
|
|
||||||
### wipe
|
|
||||||
|
|
||||||
(zsh) clears the screen and scrollback and prints an ugly horizontal line,
|
|
||||||
so you know with absolute certainty that you're looking
|
|
||||||
at the top of your history, and that your terminal's scrollback
|
|
||||||
didn't cap out and eat text.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ wipe; ./configure && make
|
|
||||||
[insert a bajillion lines you'd never be able to find the top of unless
|
|
||||||
you piped it to a file or less or wiped scrollback beforehand]
|
|
||||||
```
|
|
||||||
|
|
||||||
### yt
|
|
||||||
|
|
||||||
watches a youtube video through mpv with a bunch of audio filtering crap.
|
|
||||||
|
|
||||||
can be given a full URL or just a video ID.
|
|
||||||
remaining arguments are passed to mpv.
|
|
||||||
|
|
||||||
there exist several other variants for specific use cases.
|
|
||||||
|
|
||||||
### twitch
|
|
||||||
|
|
||||||
watches twitch streams through mpv with a bunch of audio filtering crap.
|
|
||||||
|
|
||||||
give it a username.
|
|
||||||
remaining arguments are passed to mpv.
|
|
||||||
|
|
||||||
## shell scripts
|
|
||||||
|
|
||||||
most (but not all) stuff that's written for bash will work in zsh too.
|
|
||||||
if it just says `(sh)` then it'll probably work on any shell,
|
|
||||||
but might depend on GNU awk.
|

||||||

|
|
||||||
|
|
||||||
### [arith](/sh/arith) + [hex](/sh/hex)
|
|
||||||
|
|
||||||
(zsh) does arithmetic using the shell.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ noglob arith 10**(6/20.)
|
|
||||||
1.9952623149688795
|
|
||||||
$ hex 0x221EA8-0x212020
|
|
||||||
0000FE88
|
|
||||||
```
|
|
||||||
|
|
||||||
### [aur](/sh/aur)
|
|
||||||
|
|
||||||
(bash) downloads, edits, makes, and installs packages from the [AUR.](//aur.archlinux.org)
|
|
||||||
|
|
||||||
it's a little broken.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ aur -eyoI cmdpack-uips applyppf
|
|
||||||
```
|
|
||||||
|
|
||||||
### [autosync](/sh/autosync)
|
|
||||||
|
|
||||||
(zsh) combines inotifywait and rsync.
|
|
||||||
|
|
||||||
sometimes nicer than ssh-ing into a server and running vim remotely.
|
|
||||||
|
|
||||||
### [cdbusiest](/sh/cdbusiest) + [dbusiest](/sh/dbusiest)
|
|
||||||
|
|
||||||
(zsh) cd to the directory with the most files in it (recursive).
|
|
||||||
dbusiest just outputs file counts without changing the directory.
|
|
||||||
|
|
||||||
useful for finding the biggest stinkers when archiving.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ cd
|
|
||||||
$ cdbusiest
|
|
||||||
197195 src
|
|
||||||
$ pwd
|
|
||||||
/home/notwa/src
|

|
|
||||||
a 76-character script!
|
|
||||||
|
|
||||||
### [compandy](/sh/compandy)
|
|
||||||
|
|
||||||
(zsh) a dumb thing to generate compand arguments for ffmpeg audio filters.
|
|
||||||
|
|
||||||
kinda pointless now that acompressor is wildly supported.
|
|
||||||
|
|
||||||
### [compile](/sh/compile)
|
|
||||||
|
|
||||||
(zsh) a huge mess for compiling single-file C and C++ programs.
|
|
||||||
|
|
||||||
supports gcc and clang on \*nix,
|
|
||||||
and mingw64 gcc, msvc clang, and regular msvc on Windows.
|
|
||||||
tested on x86\_64 and on ARMv7 as well.
|
|
||||||
does not support MacOS, maybe someday…
|
|
||||||
|
|
||||||
defaults to gnu11 and gnu++1z as C and C++ standards respectively.
|
|
||||||
defaults to clang, gcc, and msvc in that order.
|
|
||||||
|
|
||||||
`compile` attempts to guess the most sane switches for any program,
|
|
||||||
so that compilation may reduce to:
|
|
||||||
|
|
||||||
```sh
|
|
||||||
# debug build
|
|
||||||
compile rd.c
|
|
||||||
compile debug rd.c
|
|
||||||
# debug build with warning/error flags defined in .-shrc
|
|
||||||
# (requires .zshrc for global alias expansion)
|
|
||||||
compile WHOA rd.c
|
|
||||||
# likewise for C++
|
|
||||||
compile WHOA WELP rd.cc
|
|
||||||
compile WHOA WELP rd.cpp
|
|
||||||
# "derelease" build (release build with debug information)
|
|
||||||
compile derelease WHOA rd.c
|
|
||||||
# release build (with symbols stripped)
|
|
||||||
compile release WHOA rd.c
|
|
||||||
# hardened build (only useful on *nix)
|
|
||||||
compile hardened WHOA rd.c
|
|
||||||
# specifying compiler
|
|
||||||
compile gcc WHOA rd.c
|
|
||||||
compile msvc WHOA rd.c
|
|
||||||
compile release clang WHOA rd.c
|
|
||||||
# compile and execute (FIXME: writing to /tmp is a security concern)
|
|
||||||
compile derelease rd.c && /tmp/rd
|
|
||||||
```
|
|
||||||
|
|
||||||
also contains a helper function that dumps the commands required to
|
|
||||||
install a recent version of clang on an ubuntu machine.
|
|
||||||
|
|
||||||
### [confirm](/sh/confirm)
|
|
||||||
|
|
||||||
(bash/zsh) displays a simple yes/no prompt and returns 0 or 1 respectively.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ confirm && echo yay || echo nay
|
|
||||||
Continue? [y/N] y
|
|
||||||
yay
|
|
||||||
$ confirm && echo yay || echo nay
|
|
||||||
Continue? [y/N] n
|
|
||||||
nay
|
|
||||||
```

17229
|

```
|
|

||||||
```
|
|
||||||
$ dfu
|
|
||||||
Filesystem Used Max Left Misc
|
|
||||||
/dev 0.00 0.45 0.45 0.00
|
|

||||||
### [disf](/sh/disf)
|
|
||||||
|
|
||||||
disassembles a single function from an unstripped executable.
|
|
||||||
not robust.
|
|
||||||
|
|
||||||
### [e](/sh/e)
|
|
||||||
|
|
||||||
(zsh) wraps around $EDITOR to run as root if necessary.
|
|
||||||
this still needs some work to detect root-owned directories.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ e /etc/sudoers
|
|
||||||
[sudo] password for notwa:

|
|
||||||
|
|
||||||
(zsh) returns 0 if the current minute is divisible by a number.

||||||
note that a minute is relative to the seconds since the epoch,
|
|
||||||
not the minute of the hour.
|
|
||||||
|
|
||||||
```
|
|
||||||
# crontab usage:
|
|
||||||
* * * * * minutemaid 9 cd repo && git pull # runs every nine minutes

|
|
||||||
```
|
|
||||||
$ now
