Пролог (Prolog)
This manual page is part of the POSIX Programmer's Manual. The
Linux implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
Имя (Name)
uustat — uucp status enquiry and job control
Синопсис (Synopsis)
uustat [-q|-k jobid|-r jobid]
uustat [-s system] [-u user]
Описание (Description)
The uustat utility shall display the status of, or cancel,
previously specified uucp requests, or provide general status on
uucp connections to other systems.
When no options are given, uustat shall write to standard output
the status of all uucp requests issued by the current user.
Typical implementations of this utility require a communications
line configured to use the Base Definitions volume of
POSIX.1‐2017, Chapter 11, General Terminal Interface, but other
communications means may be used. On systems where there are no
available communications means (either temporarily or
permanently), this utility shall write an error message
describing the problem and exit with a non-zero exit status.
Параметры (Options)
The uustat utility shall conform to the Base Definitions volume
of POSIX.1‐2017, Section 12.2, Utility Syntax Guidelines.
The following options shall be supported:
-q Write the jobs queued for each machine.
-k jobid Kill the uucp request whose job identification is
jobid. The application shall ensure that the killed
uucp request belongs to the person invoking uustat
unless that user has appropriate privileges.
-r jobid Rejuvenate jobid. The files associated with jobid are
touched so that their modification time is set to the
current time. This prevents the cleanup program from
deleting the job until the jobs modification time
reaches the limit imposed by the program.
-s system Write the status of all uucp requests for remote system
system.
-u user Write the status of all uucp requests issued by user.
Операнды (Operands)

Переменные окружения (Environment variables)
The following environment variables shall affect the execution of
uustat:
LANG Provide a default value for the internationalization
variables that are unset or null. (See the Base
Definitions volume of POSIX.1‐2017, Section 8.2,
Internationalization Variables for the precedence of
internationalization variables used to determine the
values of locale categories.)
LC_ALL If set to a non-empty string value, override the values
of all the other internationalization variables.
LC_CTYPE Determine the locale for the interpretation of
sequences of bytes of text data as characters (for
example, single-byte as opposed to multi-byte
characters in arguments).
LC_MESSAGES
Determine the locale that should be used to affect the
format and contents of diagnostic messages written to
standard error, and informative messages written to
standard output.
NLSPATH Determine the location of message catalogs for the
processing of LC_MESSAGES.
Асинхронные события (Asynchronous events)
Default.
Стандартный вывод (Stdout)
The standard output shall consist of information about each job
selected, in an unspecified format. The information shall include
at least the job ID, the user ID or name, and the remote system
name.
Стандартный вывод сообщений (Stderr)
The standard error shall be used only for diagnostic messages.
Выходные файлы (Output files)
None.
Расширенное описание (Extended description)
None.
Статус выхода (Exit)
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred.
