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.


NAME
       uustat — uucp status enquiry and job control


SYNOPSIS
       uustat [-q|-k jobid|-r jobid]

       uustat [-s system] [-u user]


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.


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.


OPERANDS
       None.


STDIN
       Not used.


INPUT FILES
       None.


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.


ASYNCHRONOUS EVENTS
       Default.


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.


STDERR
       The standard error shall be used only for diagnostic messages.


OUTPUT FILES
       None.


EXTENDED DESCRIPTION
       None.


EXIT STATUS
       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.


CONSEQUENCES OF ERRORS
       Default.

       The following sections are informative.


APPLICATION USAGE
       This utility is part of the UUCP Utilities option and need not be supported by all implementations.


EXAMPLES
       None.


RATIONALE
       None.


FUTURE DIRECTIONS
       None.
