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.
