A batch job that has been deleted is no longer +subject to management by batch services. +.P +The +.IR qdel +utility is a user-accessible client of batch services that requests the +deletion of one or more batch jobs. +.P +The +.IR qdel +utility shall request a batch server to delete those batch jobs for +which a batch +.IR job_identifier +is presented to the utility. +.P +The +.IR qdel +utility shall delete batch jobs in the order in which their batch +.IR job_identifier s +are presented to the utility. +.P +If the +.IR qdel +utility fails to process any batch +.IR job_identifier +successfully, the utility shall proceed to process the remaining batch +.IR job_identifier s, +if any. +.P +The +.IR qdel +utility shall delete each batch job by sending a +.IR "Delete Job Request" +to the batch server that manages the batch job. +.P +The +.IR qdel +utility shall not exit until the batch job corresponding to each +successfully processed batch +.IR job_identifier +has been deleted. +.SH OPTIONS +None. +.SH OPERANDS +The +.IR qdel +utility shall accept one or more operands that conform to the syntax +for a batch +.IR job_identifier +(see +.IR "Section 3.3.1" ", " "Batch Job Identifier"). +.SH STDIN +Not used. +.SH "INPUT FILES" +None. +.SH "ENVIRONMENT VARIABLES" +The following environment variables shall affect the execution of +.IR qdel : +.IP "\fILANG\fP" 10 +Provide a default value for the internationalization variables that are +unset or null. (See the Base Definitions volume of POSIX.1\(hy2008, +.IR "Section 8.2" ", " "Internationalization Variables" +the precedence of internationalization variables used to determine the +values of locale categories.) +.IP "\fILC_ALL\fP" 10 +If set to a non-empty string value, override the values of all the +other internationalization variables. +.IP "\fILC_CTYPE\fP" 10 +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). +.IP "\fILC_MESSAGES\fP" 10 +.br +Determine the locale that should be used to affect the format and +contents of diagnostic messages written to standard error. +.IP "\fILOGNAME\fP" 10 +Determine the login name of the user. +.SH "ASYNCHRONOUS EVENTS" +Default. +.SH STDOUT +An implementation of the +.IR qdel +utility may write informative messages to standard output. +.SH STDERR +The standard error shall be used only for diagnostic messages. +.SH "OUTPUT FILES" +None. +.SH "EXTENDED DESCRIPTION" +None. +.SH "EXIT STATUS" +The following exit values shall be returned: +.IP "\00" 6 +Successful completion. +.IP >0 6 +An error occurred. +.SH "CONSEQUENCES OF ERRORS" +In addition to the default behavior, the +.IR qdel +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 +.IR job_identifier +does not exist on the server. Whether or not the +.IR qdel +utility waits to output the diagnostic message while attempting to +locate the job on other servers is implementation-defined. +.LP +.IR "The following sections are informative." +.SH "APPLICATION USAGE" +None. +.SH EXAMPLES +None. +.SH RATIONALE +The +.IR qdel +utility allows users and administrators to delete jobs. +.P +The +.IR qdel +utility provides functionality that is not otherwise available. For +example, the +.IR kill +utility of the operating system does not suffice. First, to use the +.IR kill +utility, the user might have to log in on a remote node, because the +.IR kill +utility does not operate across the network. Second, unlike +.IR qdel , +.IR kill +cannot remove jobs from queues. Lastly, the arguments of the +.IR qdel +utility are job identifiers rather than process identifiers, and so +this utility can be passed the output of the +.IR qselect +utility, thus providing users with a means of deleting a list of jobs. +.P +Because a set of jobs can be selected using the +.IR qselect +utility, the +.IR qdel +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. +.P +Historically, the +.IR qdel +utility has been a component of NQS, the existing practice on which it +is based. However, the +.IR qdel +utility defined in this volume of POSIX.1\(hy2008 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 +.IR qsig +utility. +.P +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" +The +.IR qdel +utility may be removed in a future version. +.SH "SEE ALSO" +.IR "Chapter 3" ", " "Batch Environment Services", +.IR "\fIkill\fR\^", +.IR "\fIqselect\fR\^", +.IR "\fIqsig\fR\^" +.P +The Base Definitions volume of POSIX.1\(hy2008, +.IR "Chapter 8" ", " "Environment Variables" +.SH COPYRIGHT +Portions of this text are reprinted and reproduced in electronic form +from IEEE Std 1003.1, 2013 Edition, Standard for Information Technology +-- Portable Operating System Interface (POSIX), The Open Group Base +Specifications Issue 7, Copyright (C) 2013 by the Institute of +Electrical and Electronics Engineers, Inc and The Open Group. +(This is POSIX.1-2008 with the 2013 Technical Corrigendum 1 applied.)
