A batch job that has been deleted is +no longer subject to management by batch services. +.LP +The \fIqdel\fP utility is a user-accessible client of batch services +that requests the deletion of one or more batch jobs. +.LP +The \fIqdel\fP utility shall request a batch server to delete those +batch jobs for which a batch \fIjob_identifier\fP is +presented to the utility. +.LP +The \fIqdel\fP utility shall delete batch jobs in the order in which +their batch \fIjob_identifier\fPs are presented to the +utility. +.LP +If the \fIqdel\fP utility fails to process any batch \fIjob_identifier\fP +successfully, the utility shall proceed to process +the remaining batch \fIjob_identifier\fPs, if any. +.LP +The \fIqdel\fP utility shall delete each batch job by sending a \fIDelete +Job Request\fP to the batch server that manages the +batch job. +.LP +The \fIqdel\fP utility shall not exit until the batch job corresponding +to each successfully processed batch +\fIjob_identifier\fP has been deleted. +.SH OPTIONS +.LP +None. +.SH OPERANDS +.LP +The \fIqdel\fP utility shall accept one or more operands that conform +to the syntax for a batch \fIjob_identifier\fP (see \fIBatch Job Identifier\fP +). +.SH STDIN +.LP +Not used. +.SH INPUT FILES +.LP +None. +.SH ENVIRONMENT VARIABLES +.LP +The following environment variables shall affect the execution of +\fIqdel\fP: +.TP 7 +\fILANG\fP +Provide a default value for the internationalization variables that +are unset or null. (See the Base Definitions volume of +IEEE\ Std\ 1003.1-2001, Section 8.2, Internationalization Variables +for +the precedence of internationalization variables used to determine +the values of locale categories.) +.TP 7 +\fILC_ALL\fP +If set to a non-empty string value, override the values of all the +other internationalization variables. +.TP 7 +\fILC_CTYPE\fP +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). +.TP 7 +\fILC_MESSAGES\fP +Determine the locale that should be used to affect the format and +contents of diagnostic messages written to standard +error. +.TP 7 +\fILOGNAME\fP +Determine the login name of the user. +.sp +.SH ASYNCHRONOUS EVENTS +.LP +Default. +.SH STDOUT +.LP +An implementation of the \fIqdel\fP utility may write informative +messages to standard output. +.SH STDERR +.LP +The standard error shall be used only for diagnostic messages. +.SH OUTPUT FILES +.LP +None. +.SH EXTENDED DESCRIPTION +.LP +None. +.SH EXIT STATUS +.LP +The following exit values shall be returned: +.TP 7 +\ 0 +Successful completion. +.TP 7 +>0 +An error occurred. +.sp +.SH CONSEQUENCES OF ERRORS +.LP +In addition to the default behavior, the \fIqdel\fP utility shall +not be required to write a diagnostic message to standard +error when the error reply received from a batch server indicates +that the batch \fIjob_identifier\fP does not exist on the +server. Whether or not the \fIqdel\fP utility waits to output the +diagnostic message while attempting to locate the job on other +servers is implementation-defined. +.LP +\fIThe following sections are informative.\fP +.SH APPLICATION USAGE +.LP +None. +.SH EXAMPLES +.LP +None. +.SH RATIONALE +.LP +The \fIqdel\fP utility allows users and administrators to delete jobs. +.LP +The \fIqdel\fP utility provides functionality that is not otherwise +available. For example, the \fIkill\fP utility of the operating system +does not suffice. First, to use the \fIkill\fP utility, the user might +have to log in on a remote node, because the \fIkill\fP utility does +not operate across the network. Second, unlike \fIqdel\fP, \fIkill\fP +cannot remove jobs from queues. Lastly, the arguments of the \fIqdel\fP +utility are job +identifiers rather than process identifiers, and so this utility can +be passed the output of the \fIqselect\fP utility, thus providing +users with a means of deleting a list of jobs. +.LP +Because a set of jobs can be selected using the \fIqselect\fP utility, +the \fIqdel\fP +utility has not been complicated with options that provide for selection +of jobs. Instead, the batch jobs to be deleted are +identified individually by their job identifiers. +.LP +Historically, the \fIqdel\fP utility has been a component of NQS, +the existing practice on which it is based. However, the +\fIqdel\fP utility defined in this volume of IEEE\ Std\ 1003.1-2001 +does not provide an option for specifying a signal +number to send to the batch job prior to the killing of the process; +that capability has been subsumed by the \fIqsig\fP utility. +.LP +A discussion was held about the delays of networking and the possibility +that the batch server may never respond, due to a down +router, down batch server, or other network mishap. The DESCRIPTION +records this under the words "fails to process any job +identifier". In the broad sense, the network problem is also an error, +which causes the failure to process the batch job +identifier. +.SH FUTURE DIRECTIONS +.LP +None. +.SH SEE ALSO +.LP +\fIBatch Environment Services\fP , \fIkill\fP() , \fIqselect\fP , +\fIqsig\fP +.SH COPYRIGHT +Portions of this text are reprinted and reproduced in electronic form +from IEEE Std 1003.1, 2003 Edition, Standard for Information Technology +-- Portable Operating System Interface (POSIX), The Open Group Base +Specifications Issue 6, Copyright (C) 2001-2003 by the Institute of +Electrical and Electronics Engineers, Inc and The Open Group.
