bashbug
GNU bashbug, version 5.2.21-release
Usage: /usr/bin/bashbug [--help] [--version] [bug-report-email-address]
Bashbug is used to send mail to the Bash maintainers
for when Bash doesn't behave like you'd like, or expect.
Bashbug will start up your editor (as defined by the shell's
EDITOR environment variable) with a preformatted bug report
template for you to fill in. The report will be mailed to the
bug-bash mailing list by default. See the manual for details.
If you invoke bashbug by accident, just quit your editor without
saving any changes to the template, and no bug report will be sent.bc

If the tune is specified on the command line then each argument contains a command group. If it's read from a file then
each line contains a command group. Each specified file contains a different tune.
A command group is zero or more commands separated from one another by whitespace. A number sign [#] at the beginning or
after whitespace begins a comment.
Each command is a letter immediately followed by its parameter(s). In the following descriptions, <angle brackets> are
used to show that a parameter is required and [square brackets] are used to show that it's optional. While a command
doesn't contain any spaces, some of the descriptions include them for clarity. When there is a choice, {curly brackets}
combined with vertical bar [|] separators are used. These commands are recognized:
a-g the seven standard note letters
k change the key
m a MIDI note number
p change the note period
r a rest
t change the tempo
A note command begins with any of the seven standard note letters (a, b, c, d, e, f, g). Its general syntax is:
<letter> [octave] [accidental] [duration]
The m<number>[duration] command specifies a note by its MIDI number. The number must be within the range 1 through 127.
MIDI stands for Musical Instrument Digital Interface. It specifies that Middle-C is note 60, that a higher number
represents a higher pitch, and that adjacent numbers represent notes that differ in pitch by 1 semitone.
The r[duration] command specifies a rest - the musical way of saying "no note".
Octaves are numbered according to International Pitch Notation, so the scale starting with Middle-C is octave 4. Octaves
0 through 9 may be specified, although notes above g9 can't be played (this is a MIDI limitation). If the octave of the
first note of the tune isn't specified then octave 4 is assumed. If it isn't specified for any other note then the
technique used in braille music is used. Normally, the octave of the previous note is assumed. If, however, the note in
an adjacent octave is three semitones or less away from the previous one then the new octave is assumed.
If the accidental (sharp, flat, or natural) isn't specified then the one defined by the current key is assumed. It may
be specified as a plus sign [+] for sharp, a minus sign [-] for flat, or an equal sign [=] for natural. More than one
sharp or flat (+ or -) may be specified.
If the duration of a ntoe isn't specified then the duration of the previous note is assumed. If the duration of the
first note isn't specified then the length of one beat at the default tempo is assumed. A duration may be specified in
two ways:
@<number>: It may be explicitly set by prefixing the number of milliseconds with an at sign [@].
[*<multiplier>] [/<divisor>]: It may be calculated by applying a multiplier and/or a divisor, in that order, to the
length of one beat at the current tempo. The multiplier is a number prefixed with an asterisk [*] and must be within the
range 1 through 16. The divisor is a number prefixed with a slash [/] and must be within the range 1 through 128. Both
default to 1.
Both ways of specifying the duration allow any number of dots [.] to be appended. These dots modify the duration of the
note in the same way that adding dots to a note does in print (and braille) music. For example: At a tempo of 120 (beats
per minute), a whole note (4 beats) has a duration of 2 seconds. So:
#dots seconds beats
0 2 4
1 3 6

The k command changes the key. The initial key is C Major, i.e. it has no accidentals. This command has two forms:
k<root>[mode]: The root note must be one of the seven standard note letters (a, b, c, d, e, f, g). The mode may also be
specified. Any Unambiguous abbreviation of its name may be used. The recognized mode names are: major, minor, ionian,
dorian, phrygian, lydian, mixolydian, aeolian, locrian.
k[count]<accidental>: The key may also be implied by specifying how many accidentals (sharps or flats) it has. The count
must be a number within the range 1 through 12 (the number of semitones within a scale). The accidental must be either a
plus sign [+] for sharp or a minus sign [-] for flat. If the count is specified then there must be one accidental
indicator. If it isn't specified then more than one accidental indicator may be specified.
The p<number> command changes the note period - the amount of time within its duration that a note is on. It's a
percentage, and must be within the range 1 through 100. The initial note period is 80 percent.
The t<number> command changes the tempo (speed). It's the number of beats per minute, and must be within the range 40
through 255. The initial tempo is 120 beats per minute.broadwayd

busybox
BusyBox v1.36.1 (Ubuntu 1:1.36.1-6ubuntu3) multi-call binary.
BusyBox is copyrighted by many authors between 1998-2015.

Usage: busybox [function [arguments]...]
or: busybox --list[-full]

or: function [arguments]...
BusyBox is a multi-call binary that combines many common Unix
utilities into a single executable. The shell in this build
is configured to run built-in utilities without $PATH search.
You don't need to install a link to busybox for each utility.
To run external program, use full path (/sbin/ip instead of ip).
