obligatory personal dotfiles repository
(plus some little shell scripts)
there's probably a lot of subtle things gone uncredited, but oh well.
commands defined RC files
such as .bashrc .zshrc and -shrc
TODO
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 anything,
but probably depends on GNU awk.
arith + hex
(zsh) does arithmetic using the shell.
$ arith 10**(6/20.)
1.9952623149688795
$ hex 0x221EA8-0x212020
0000FE88
aur
(bash) downloads, edits, makes, and installs packages from the AUR.
a little broken.
$ aur -eyoI cmdpack-uips applyppf
cdbusiest + 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
colors
(bash) print out all the foreground and background terminal color combinations. a 76-character script!
compandy
(zsh) a dumb thing to generate compand arguments for ffmpeg audio filters.
confirm
(bash/zsh) displays a simple yes/no prompt and returns 0 or 1 respectively.
days
(bash) compute days since a date.
$ days 'January 1 1970'
16979

$ dfu

e
(zsh) wraps around $EDITOR to run as root if necessary. needs some work.
$ e /etc/sudoers
[sudo] password for notwa:
gitall
(zsh) asks you to update most of the git repos it finds. i don't really use this.
is_empty
(bash) returns 0 if the directory given by $1 is empty.
isup
(zsh) returns 0 if a website returns a 2xx HTTP code.
$ isup google.com && echo yay || echo nay
yay

nay
logs
(bash/zsh) just wraps around journalctl. i don't remember how it works exactly.
lol-twitter
(zsh) checks if usernames (from stdin) are available on twitter.
seems to return a 403 code these days, but you could probably fix that.
lsarchive + unarchive
(zsh) guess what these do. written by Sorin Ionescu. includes autocomplete files.
lsz
(zsh) a needlessly fancy alternative to ls.
based on lsf or something, which might be a gist somewhere.
you can find similar, more mature projects on github.
minutemaid
(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
mkgist
(bash) makes a (mostly) empty gist and pulls it so you never have to visit the site. i think this is broken.
monitor
(zsh) literally just watch as a shell script. kinda nice though.
mw + mw-cyg
(zsh) manages a ton of environment variables for cross-compiling programs. you'll want to tweak this if you use it yourself.
now
(bash) returns the local date-time in a sortable format. will take a date or a file as an argument too.
$ now
2016-06-27_19551873
$ now ./now
2016-03-12_25288645
$ now '@1234567890'

$ pacbm | head -n -1 | tail -2
