“Seek not to walk the path of the masters; seek what they sought.”
|
||||||
|
– Matsuo Basho
|
||||||
|
|
||||||
|
The Bonsai core utilities are the result of the careful examination of the
|
||||||
|
current state of POSIX and Unix utilies. The Unix Philosophy, “do one thing and
|
||||||
|
do it well” is its core but these tools do not cling to the names of the past.
|
||||||
|
|
||||||
|
The era of the original Unix tools has been long and fruitful, but they have
|
||||||
|
their flaws. The new, non-POSIX era of this project started with frustration
|
||||||
|
with the way certain tools work and how other projects that extend POSIX don’t
|
||||||
|
make anything better.
|
||||||
|
|
||||||
|
This project will not follow in the footsteps of GNU; extensions of POSIX will
|
||||||
|
not be found here. GNU extensions are a gateway to the misuse of the shell. The
|
||||||
|
Bonsai core utilities will intentionally discourage use of the shell for
|
||||||
|
purposes beyond its scope.
|
||||||
|
|
||||||
|
See docs/ for more on the specific utilities currently implemented.

.TH intcmp 1

|
||||||
|
.SH NAME
|
||||||
|
|
||||||
|
intcmp \(en compare integers
|
||||||
|
|
||||||
|
.SH SYNOPSIS
|
||||||
|
|
||||||
|
intcmp
|
||||||
|
.RB ( -eghl )
|
||||||
|
.RB [ integer ]
|
||||||
|
.RB [ integer... ]
|
||||||
|
|
||||||
|
.SH DESCRIPTION
|
||||||
|
|
||||||
|
Intcmp compares integers.
|
||||||
|
|
||||||
|
.SH USAGE
|
||||||
|
|
||||||
|
The -e option permits given integers to be equal to each other. If combined
|
||||||
|
with -g or -l, only adjacent integers in the argument sequence can be equal.
|
||||||
|
.PP
|
||||||
|
The -g option permits a given integer to be greater than the following integer.
|
||||||
|
.PP
|
||||||
|
The -l option permits a given integer to be less than the following integer.
|
||||||
|
.PP
|
||||||
|
It may help to think of the -e, -g, and -l options as equivalent to the
|
||||||
|
infix algebraic “=”, “>”, and “<” operators respectively, with each option
|
||||||
|
putting its symbol between every given integer. For example,
|
||||||
|
.R intcmp -l 1 2 3
|
||||||
|
is equivalent to evaluating "1 < 2 < 3".
|
||||||
|
|
||||||
|
.SH DIAGNOSTICS
|
||||||
|
|
||||||
|
Intcmp exits 0 for a valid expression and 1 for an invalid expression.
|
||||||
|
.PP
|
||||||
|
Intcmp prints a debug message and exits with the appropriate sysexits(3) error
|
||||||
|
code in the event of an error.
|
||||||
|
|
||||||
|
.SH BUGS
|
||||||
|
|
||||||
|
There are multiple ways to express compound comparisons; “less than or equal
|
||||||
|
to” can be -le or -el, for example.
|
||||||
|
.PP
|
||||||
|
The inequality comparison is -gl or -lg for “less than or greater than”; this
|
||||||
|
is elegant but unintuitive.
|
||||||
|
.PP
|
||||||
|
-egl, "equal to or less than or greater than", exits 0 no matter what for valid
|
||||||
|
program usage and may be abused to function as an integer validator.
|
||||||
|
Use str(1) instead.
|
||||||
|
|
||||||
|
.SH RATIONALE
|
||||||
|
|
||||||
|
The traditional tool for integer comparisons in POSIX and other Unix shells has
|
||||||
|
been test(1). This tool also handles string comparisons and file scrutiny.
|
||||||
|
These parts of its functionality have been broken out into multiple utilities.
|
||||||
|
|
||||||
|
Strcmp’s functionality may be performed on a POSIX-compliant system with
|
||||||
|
test(1p).

|
||||||
|
.SH NAME
|
||||||
|
|
||||||
|
npc \(en show non-printing characters
|

|

npc
|
||||||
|
.RB ( -eht )
|
||||||
|
|
||||||
|
.SH DESCRIPTION
|
||||||
|
|
||||||
|
Npc reads from standard input and writes to standard output, replacing non-
|
||||||
|
printing characters with printable equivalents. Control characters print as a
|
||||||
|
carat ('^') followed by the character '@' through '_' corresponding to the
|
||||||
|
character replaced (e.g. control-X becomes "^X"). The delete character (0x7F)
|
||||||
|
becomes "^?". Characters with the high bit set (>127) are printed as "M-"
|
||||||
|
followed by the graphical representation for the same character without the
|
||||||
|
high bit set.
|
||||||
|
.PP
|
||||||
|
The
|
||||||
|
.B -e
|
||||||
|
option prints a currency sign ('$') before each line ending.
|
||||||
|
.PP
|
||||||
|
The
|
||||||
|
.B -t
|
||||||
|
option prints tab characters as "^I" rather than a literal horizontal tab.
|
||||||
|
|
||||||
|
.SH DIAGNOSTICS
|
||||||
|
|
||||||
|
Npc prints a debug message and exits with the appropriate sysexits(3) error
|
||||||
|
code in the event of an error, otherwise it exits successfully.
|
||||||
|
|
||||||
|
.SH BUGS
|
||||||
|
|
||||||
|
Npc operates in single-byte chunks regardless of intended encoding.
|
||||||
|
|
||||||
|
.SH RATIONALE
|
||||||
|
|
||||||
|
POSIX currently lacks a way to display non-printing characters in the terminal
|
||||||
|
using a standard tool. A popular extension to cat(1p), the -v option, is the
|
||||||
|
bandage solution GNU and other software suites use.
|
||||||
|
|
||||||
|
This functionality should be a separate tool because its usefulness extends
|
||||||
|
beyond that of cat(1p).

|
||||||
|
.SH NAME
|
||||||
|
|
||||||
|
str \(en test the character types of string arguments
|
||||||
|
|
||||||
|
.SH SYNOPSIS
|
||||||
|

||||||
|
str
|
||||||
|
.RB [ type ]
|
||||||
|
.RB [ string... ]
|
||||||
|
|
||||||
|
.SH DESCRIPTION
|
||||||
|
|
||||||
|
Str tests each character in an arbitrary quantity of string arguments against
|
||||||
|
the function of the same name within ctype(3).
|
||||||
|
|
||||||
|
.SH DIAGNOSTICS
|
||||||
|
|
||||||
|
Str exits successfully if all tests pass and unsuccessfully if a test failed.
|
||||||
|
.PP
|
||||||
|
Str will exit unsuccessfully if a string is empty, as none of its contents
|
||||||
|
passed the test.
|
||||||
|
.PP
|
||||||
|
Str will print a message to standard error and exit unsuccessfully if used
|
||||||
|
improperly.
|
||||||
|
|
||||||
|
.SH DEPRECATED FEATURES
|
||||||
|
|
||||||
|
Str used to have an "isvalue" type as an extension to ctype(3). This was
|
||||||
|
removed in favor of using strcmp(1) to compare strings against the empty string
|
||||||
|
('').
|
||||||
|
|
||||||
|
.SH BUGS
|
||||||
|
|
||||||
|
There's no way of knowing which argument failed the test without re-testing
|
||||||
|
arguments individually.
|
||||||
|
.PP
|
||||||
|
If a character in a string isn't valid ASCII str will exit unsuccessfully.

|
||||||
|
Strcmp exits successfully if the strings are identical. Otherwise, strcmp exits
|
||||||
|
with the value 1 if an earlier string has a greater byte value than a later
|
||||||
|
string (e.g.
|
||||||
|
.R strcmp b a
|
||||||
|
)
|
||||||
|
and 255 if an earlier string has a lesser byte value (e.g.
|
||||||
|
.R strcmp a b
|
||||||
|
).
|
||||||
|
|
||||||
|
.SH DIAGNOSTICS
|
||||||
|
|
||||||
|
Strcmp will print an error message and exit unsuccessfully with a status
|
||||||
|
described in sysexits(3) if used incorrectly (given less than two operands).
|
||||||
|
|
||||||
|
.SH UNICODE
|
||||||
|
|
||||||
|
Strcmp will exit unsuccessfully if the given strings are not identical;
|
||||||
|
Unicode strings may need to be normalized if the intent is to check visual
|
||||||
|
similarity and not byte similarity.
|
||||||
|
|
||||||
|
.SH RATIONALE
|
||||||
|
|
||||||
|
The traditional tool for string comparisons in POSIX and other Unix shells has
|
||||||
|
been test(1). This tool also handles integer comparisons and file scrutiny.
|
||||||
|
These parts of its functionality have been broken out into multiple utilities.
|
||||||
|
|
||||||
|
Strcmp’s functionality may be performed on a POSIX-compliant system with
|
||||||
|
test(1p).
