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.1‐2008, 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.1‐2008, 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.1‐2008, 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.
