_(plus some little shell scripts)_
quick install for random boxes:
```
# with curl:
cd && curl -L https://github.com/notwa/rc/archive/master.tar.gz | tar zx && mv rc-master rc && rc/install
# with wget:
cd && wget -O - https://github.com/notwa/rc/archive/master.tar.gz | tar zx && mv rc-master rc && rc/install
```
the following shells are taken into consideration, ordered from most to least compatible:
* zsh
* bash
* dash
* ash (busybox)

## shell functions
### [archive](/sh/archive#L4)
create an archive file in one of a few formats.
borrowed from [prezto.](https://github.com/sorin-ionescu/prezto)
### [argc](/sh/argc#L4)
validate the number of arguments in a function.
```sh
# usage: myfunc() { argc $# -(eq|le|ge) [0-9] "$0" || return; }
myfunc() {
# use one of the following:
argc $# -eq N "$0" || return
argc $# -le N "$0" || return
argc $# -ge N "$0" || return
# where N is an integer between 0 and 9.
}
```
### [arith](/sh/arith#L7)
perform arithmetic using the shell and display the result.
see also [`hex`](#hex) and [`bin`](#bin).
this example requires zsh:
```
% db=6
% noglob arith 10**(db/20.)
1.9952623149688795
```
### [aur](/sh/aur#L5)
download, edit, make, and install packages from the
[AUR.](https://aur.archlinux.org/)
it's a little broken.
```
$ aur -eyoI cmdpack-uips applyppf
```
### [autosync](/sh/autosync#L6)
combine `inotifywait` and `rsync`.
this is sometimes nicer than `ssh`-ing into a server and running `vim` remotely.
### [bak](/sh/bak#L4)
backup files by creating copies and appending ".bak" to their names.
this calls itself recursively to avoid clobbering existing backups.
```
$ touch -d '2001-12-25 16:30:00' butts
$ bak butts
$ touch butts
$ bak butts
$ ls -l
total 0
-rw-r--r-- 1 notwa None 0 Aug 1 08:02 butts
-rw-r--r-- 1 notwa None 0 Aug 1 08:02 butts.bak
-rw-r--r-- 1 notwa None 0 Dec 25 2001 butts.bak.bak
```
### [baknow](/sh/baknow#L4)
backup files by appending their timestamps given by [`now`.](#now)
```
$ touch -d '2001-12-25 16:30:00' butts
$ baknow butts
$ baknow butts
cp: overwrite 'butts.2001-12-26_01800000.bak'? n
$ ls -l
total 0
-rw-r--r-- 1 notwa None 0 Dec 25 2001 butts
-rw-r--r-- 1 notwa None 0 Dec 25 2001 butts.2001-12-26_01800000.bak
```
### [baks](/sh/baks#L5)
backup files by copying each and appending *the current* date-time,
irrespective of when the files were modified or created.
```
$ touch -d '2001-12-25 16:30:00' butts
$ baks butts
$ baks butts
$ ls -l
total 0
-rw-r--r-- 1 notwa None 0 Dec 25 2001 butts
-rw-r--r-- 1 notwa None 0 Dec 25 2001 butts.21-08-01_14-54-07.bak
-rw-r--r-- 1 notwa None 0 Dec 25 2001 butts.21-08-01_14-54-09.bak
```
### [bin](/sh/bin#L7)
perform arithmetic using the shell and display the result as
an unsigned 8-bit integer in binary.
see also [`arith`](#arith) and [`hex`](#hex).
```
$ bin 123
01111011
```
### [busiest](/sh/busiest#L4)

144181 src
48840 work
21042 play
```
### [colors](/sh/colors#L4)

excluding boilerplate, this script is a mere 76 characters long!
![terminal colors](https://eaguru.guru/t/terminal-colors.png)
### [setup_clang_ubuntu (sh/compile)](/sh/compile#L4)
print (but don't execute) the commands necessary to install
a fairly recent version of clang on ubuntu-based distros.
```sh
$ setup_clang_ubuntu bionic
wget -O - http://apt.llvm.org/llvm-snapshot.gpg.key | apt-key add -
echo -n "deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic main
# deb-src http://apt.llvm.org/bionic/ llvm-toolchain-bionic main
# 12
deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic-12 main
# deb-src http://apt.llvm.org/bionic/ llvm-toolchain-bionic-12 main
" > /etc/apt/sources.list.d/llvm-toolchain-bionic.list
apt-get update
apt-get install clang-12
apt-get install lld-12

```
### [compile](/sh/compile#L47)
compile single-file C and C++ programs, messily.
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 ~/sh/arrays
# (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
```
### [confirm](/sh/confirm#L4)
display a simple yes-or-no prompt and return 0-or-1 respectively.
```
$ confirm && echo yay || echo nay
Continue? [y/N] y
yay
$ confirm && echo yay || echo nay
Continue? [y/N] n
nay
```
a real world example:
```
$ g1 && confirm && git commit -a --amend --no-edit
daf84e3 document a ton of stuff
Continue? [y/N] y
[master 92bdf76] document a ton of stuff

### [decently](/sh/decently#L6)
given a list of directories, update the last-modified timestamp
of each argument to that of the most recent file that it contains.
note that *files* are found recursively, but only the

has its timestamp updated. symlinks are followed.
`.git` subdirectories are skipped over.
the timestamps of subdirectories are ignored.
### [dfu](/sh/dfu#L4)

0000FE88
```
**NOTE:** there also exists a hex(1) program provided by
the *basez* package that i don't use.
### [ify](/sh/ify#L4)
pipe one command through another, so you can still pass arguments to the former.
this is mainly useful for aliases. 99% of the time you'll use this with `less`.

as it stands, this mostly just handles some environment variables.
try this: `maybesudo_ -u "$USER" printenv`
### [minutemaid](/sh/minutemaid#L4)
check if the current minute is divisible by a given number,
and optionally execute a command if it is. if a command is given,
either execute the command and return its exit value,
or execute nothing and return 0. if a command is omitted,
either return 0 on the minute, or return 1.
note that a "minute" is relative to the seconds since the epoch,
not the minute of the hour. this ensures that commands will run
roughly every N minutes, regardless of the minute hand on the clock.
note that `minutemaid 1` will always return 0,
and `minutemaid 1 command` will always execute the command,
since every integral interval is evenly divisible by 1.
`minutemaid 0`, and any negative interval, is an error.
```
# crontab usage:
* * * * * minutemaid 9 ~/work/do_my_bidding # runs every nine minutes
# loop usage:
until minutemaid 9; do sleep 5; done
echo the wait is finally over; date
# improper usage:

program provided by the *note* package that i don't use.
### [now](/sh/now#L4)
print a date-time (UTC) in a sortable format.

#define __UINT_LEAST16_TYPE__ short unsigned int
#define __ORDER_BIG_ENDIAN__ 4321

./sh
```
### [rot13](/sh/rot13#L6)

handling already-commented and already-quoted text.
this allows `shcom` to be used with vim's visual selections
to update existing code examples.
as a simple example, `echo hey | shcom` produces, verbatim:
```
hey
```

**NOTE:** don't use `stfu` for handling sensitive data or commands!
use it for 7zip.
note that the tail commands in the example below are from `stfu` itself;
they are echoed to reveal the temp paths for any further investigation.
```
$ touch butts
$ STFU_TAIL=5
$ stfu 7z a butts.7z butts
$ stfu 7z a butts.7z asses
command failed with exit status 1:
7z a butts.7z asses
$ tail -n 5 /tmp/stfu.CoJ0vmJsqA/out_1627942118
Scan WARNINGS for files and folders:
asses : The system cannot find the file specified.
----------------

WARNING: The system cannot find the file specified.
asses
```
### [sum](/sh/sum#L4)
compute the summation of its arguments without forking processes.
this relies on the shell's built-in arithmetic operators.
```
$ sum 1 2 3
6
```
**TODO:** consider renaming because sum(1) already exists.
### [sv](/sh/sv#L4)
collect the lastmost value of every key.
the field separator can be given as its sole argument,
it defaults to a single space otherwise.
```
$ echo "alpha=first\nbeta=second\nalpha=third" | sv =
alpha=third
beta=second
```
this next example uses `sv` to only print the lastmost line
matching a pattern in each file. in other words, it uses
the filename printed by grep as the key in its key-value pairs.
```
$ cd ~/play/hash && grep -r 'ing$' . | sv :
./dic_win32.txt:WriteProfileString
./cracklib-small.txt:zoning
./english-words.txt:zooming
./usernames-125k.txt:flats_gaming
./cain.txt:zoografting
./pokemon.txt:Fletchling
./pokemon8.txt:Fletchling
```
**TODO:** rename because busybox(1) sv already exists.
### [trash](/sh/trash#L4)
output a given number of bytes from `/dev/random`.
```
$ trash 10 | xxp
3A A5 4F C7 6D 89 E7 D7 F7 0C
```
**TODO:** consider renaming because trash(1) already exists.
### [trunc](/sh/trunc#L4)

### [xxp](/sh/xxp#L4)
act like `xxd -p`, but nicely formatted.
**TODO:** support `-r` (reverse) argument.
