.TH STR 1
|
||||
|
||||
.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.
