|
|
|
|
### [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)

```
|
|
% db=6
|
|
% noglob arith 10**(db/20.)

|
|
$ 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)
|
|
|

|
|
irrespective of when the files were modified or created.
|
|
|
|
```
|
|

|
|
$ baks butts
|
|
$ baks butts
|
|

|
|
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
|
|
```
|
|
|
|
### [burl](/sh/burl#L4)
|
|
|
|

|
|
inspired by [hackshell.sh.](https://thc.org/hs)
|

|
|
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 -
|

|
|
# deb-src http://apt.llvm.org/bionic/ llvm-toolchain-bionic-12 main
|

|
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)
|
|
|

$ 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

this is mainly useful for aliases. 99% of the time you'll use this with `less`.

### [maybesudo](/sh/maybesudo#L4)
|

|
|
|
|
### [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:
|
|
while minutemaid 1; do sleep 1; done
|
|
echo this will never happen

|
|
|
|
### [rs](/sh/rs#L4)

|
|
currently only works on Windows (gdigrab).

### [shcom](/sh/shcom#L4)

comment out text from stdin and wrap it in a markdown blockquote
|
|
for docstrings. this contains some extra logic for
|
|
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
|
|
```

invoke a command, silencing stdout and stderr *unless* the command fails.
|
|
|
|
**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
|

|
|
|
|
### [sum](/sh/sum#L4)
|
|
|
|

|
|
6

$ 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
