A batch job is signaled by sending a request +to the batch server that manages the batch job. The \fIqsig\fP utility +is a user-accessible batch client that requests the +signaling of a batch job. +.LP +The \fIqsig\fP utility shall signal those batch jobs for which a batch +\fIjob_identifier\fP is presented to the utility. The +\fIqsig\fP utility shall not signal any batch jobs whose batch \fIjob_identifier\fPs +are not presented to the utility. +.LP +The \fIqsig\fP utility shall signal batch jobs in the order in which +the corresponding batch \fIjob_identifier\fPs are +presented to the utility. If the \fIqsig\fP utility fails to process +a batch \fIjob_identifier\fP successfully, the utility shall +proceed to process the remaining batch \fIjob_identifier\fPs, if any. +.LP +The \fIqsig\fP utility shall signal batch jobs by sending a \fISignal +Job Request\fP to the batch server that manages the +batch job. +.LP +For each successfully processed batch \fIjob_identifier\fP, the \fIqsig\fP +utility shall have received a completion reply to +each \fISignal Job Request\fP sent to a batch server at the time the +utility exits. +.SH OPTIONS +.LP +The \fIqsig\fP utility shall conform to the Base Definitions volume +of IEEE\ Std\ 1003.1-2001, Section 12.2, Utility Syntax Guidelines. +.LP +The following option shall be supported by the implementation: +.TP 7 +\fB-s\ \fP \fIsignal\fP +Define the signal to be sent to the batch job. +.LP +The \fIqsig\fP utility shall accept a \fIsignal\fP option-argument +that is either a symbolic signal name or an unsigned +integer signal number (see the POSIX.1-1990 standard, Section 3.3.1.1). +The \fIqsig\fP utility shall accept signal names for which +the SIG prefix has been omitted. +.LP +If the \fIsignal\fP option-argument is a signal name, the \fIqsig\fP +utility shall send that name. +.LP +If the \fIsignal\fP option-argument is a number, the \fIqsig\fP utility +shall send the signal value represented by the +number. +.LP +If the \fB-s\fP option is not presented to the \fIqsig\fP utility, +the utility shall send the signal SIGTERM to each signaled +batch job. +.sp +.SH OPERANDS +.LP +The \fIqsig\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 +\fIqsig\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 \fIqsig\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 \fIqsig\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 \fIqsig\fP utility waits to output the +diagnostic message while attempting to locate the batch 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 \fIqsig\fP utility allows users to signal batch jobs. +.LP +A user may be unable to signal a batch job with the \fIkill\fP utility +of the operating +system for a number of reasons. First, the process ID of the batch +job may be unknown to the user. Second, the processes of the +batch job may be on a remote node. However, by virtue of communication +between batch nodes, the \fIqsig\fP utility can arrange for +the signaling of a process. +.LP +Because a batch job that is not running cannot be signaled, and because +the signal may not terminate the batch job, the +\fIqsig\fP utility is not a substitute for the \fIqdel\fP utility. +.LP +The options of the \fIqsig\fP utility allow the user to specify the +signal that is to be sent to the batch job. +.LP +The \fB-s\fP option allows users to specify a signal by name or by +number, and thus override the default signal. The +POSIX.1-1990 standard defines signals by both name and number. +.LP +The \fIqsig\fP utility is a new utility, \fIvis-a-vis\fP existing +practice; it has been defined in this volume of +IEEE\ Std\ 1003.1-2001 in response to user-perceived shortcomings +in existing practice. +.SH FUTURE DIRECTIONS +.LP +None. +.SH SEE ALSO +.LP +\fIBatch Environment Services\fP, \fIkill\fP(), \fIqdel\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.
